Obesity results from the excessive accumulation of fat that exceeds the body’s skeletal and physical standards. According to the National Institutes of Health (NIH), an increase in 20 percent or more above your ideal body weight is the point at which excess weight becomes a health risk. Today 97 million Americans, more than one-third of the adult population, are overweight or obese. An estimated 5 to 10 million of those are considered morbidly obese.
Obesity becomes “morbid” when it reaches the point of significantly increasing the risk of one or more obesity-related health conditions or serious diseases (also known as co-morbidities) that result either in significant physical disability or even death. As you read about morbid obesity you may also see the term “clinically severe obesity” used. Both are descriptions of the same condition and can be used interchangeably. Morbid obesity is typically defined as being 100 lbs. or more over ideal body weight or having a Body Mass Index of 40 or higher. According to the National Institutes of Health Consensus Report, morbid obesity is a serious disease and must be treated as such. It is a chronic disease, meaning that its symptoms build slowly over an extended period of time.
The reasons for obesity are multiple and complex. Despite conventional wisdom, it is not simply a result of overeating. Research has shown that in many cases a significant, underlying cause of morbid obesity is genetic. Studies have demonstrated that once the problem is established, efforts such as dieting and exercise programs have a limited ability to provide effective long-term relief.
Science continues to search for answers. But until the disease is better understood, the control of excess weight is something patients must work at for their entire lives. That is why it is very important to understand that all current medical interventions, including weight loss surgery, should not be considered medical cures. Rather they are attempts to reduce the effects of excessive weight and alleviate the serious physical, emotional and social consequences of the disease.
The underlying causes of severe obesity are not known. There are many factors that contribute to the development of obesity including genetic, hereditary, environmental, metabolic and eating disorders. There are also certain medical conditions that may result in obesity like intake
of steroids and hypothyroidism.
Numerous scientific studies have established that your genes play an important role in your tendency to gain excess weight.
The Pima Paradox
The Pima Indians are known in scientific circles as one of the heaviest groups of people in the world. In fact, National Institutes of Health researchers have been studying them for more than 35 years. Some adults weigh more than 500 pounds, and many obese teenagers are suffering from diabetes, the disease most frequently associated with obesity.
But here’s a really interesting fact – a group of Pima Indians living in Sierra Madre, Mexico, does not have a problem with obesity and its related diseases. Why not?
The leading theory states that after many generations of living in the desert, often confronting famine, the most successful Pima were those with genes that helped them store as much fat as possible during times when food was available. Now those fat-storing genes work against them.
Though both populations consume a similar number of calories each day, the Mexican Pima still live much like their ancestors did. They put in 23 hours of physical labor each week and eat a traditional diet that’s very low in fat. The Arizona Pima live like most other modern Americans, eating a diet consisting of around 40 percent fat and engaging in physical activity for only two hours a week.
The Pima apparently have a genetic predisposition to gain weight. And the environment in which they live – the environment in which most of us live – makes it nearly impossible for the Arizona Pima to maintain a normal, healthy body weight.
Environmental and genetic factors are obviously closely intertwined. If you have a genetic predisposition toward obesity, then the modern American lifestyle and environment may make controlling weight more difficult.
Fast food, long days sitting at a desk, and suburban neighborhoods that require cars all magnify hereditary factors such as metabolism and efficient fat storage.
For those suffering from morbid obesity, anything less than a total change in environment usually results in failure to reach and maintain a healthy body weight.
We used to think of weight gain or loss as only a function of calories ingested and then burned. Take in more calories than you burn, gain weight; burn more calories than you ingest, lose weight. But now we know the equation isn’t that simple.
Obesity researchers now talk about a theory called the “set point,” a sort of thermostat in the brain that makes people resistant to either weight gain or loss. If you try to override the set point by drastically cutting your calorie intake, your brain responds by lowering metabolism and slowing activity. You then gain back any weight you lost.
Eating Disorders & Medical Conditions
Weight loss surgery is not a cure for eating disorders. And there are medical conditions, such as hypothyroidism, that can also cause weight gain. That’s why it’s important that you work with your doctor to make sure you do not have a condition that should be treated with medication and counseling.
Morbid obesity brings with it an increased risk for a shorter life expectancy. For individuals whose weight exceeds twice their ideal body weight (that’s about 2-6% of the U.S. population), the risk of an early death is doubled compared to non-obese individuals. The risk of death from diabetes or heart attack is five to seven times greater. Even beyond the issue of obesity-related health conditions, weight gain alone can lead to a condition known as “end-stage” obesity where, for the most part, no treatment options are available. Yet an early death is not the only potential consequence. Social, psychological and economic effects of morbid obesity, however unfair, are real and can be especially devastating.
Obesity-related health conditions are health conditions that, whether alone or in combination, can significantly reduce your life expectancy. A partial list of some of the more common conditions follows. Your doctor can provide you with a more detailed and complete list:
Type 2 Diabetes. Obese individuals develop a resistance to insulin, which regulates blood sugar levels. Over time, the resulting high blood sugar can cause serious damage to the body.
High blood pressure/Heart disease. Excess body weight strains the ability of the heart to function properly. The resulting hypertension (high blood pressure) can result in strokes, as well as inflict significant heart and kidney damage.
Osteoarthritis of weight-bearing joints. The additional weight placed on joints, particularly knees and hips, results in rapid wear and tear, along with pain caused by inflammation. Similarly, bones and muscles of the back are constantly strained, resulting in disk problems, pain and decreased mobility.
Sleep apnea/Respiratory problems. Fat deposits in the tongue and neck can cause intermittent obstruction of the air passage. Because the obstruction is increased when sleeping on your back, you may find yourself waking frequently to reposition yourself. The resulting loss of sleep often results in daytime drowsiness and headaches.
Gastroesophageal reflux/Heartburn. Acid belongs in the stomach and seldom causes any problem when it stays there. When acid escapes into the esophagus through a weak or overloaded valve at the top of the stomach, the result is called gastroesophageal reflux, and “heartburn” and acid indigestion are common symptoms. Approximately 10-15% of patients with even mild sporadic symptoms of heartburn will develop a condition called Barrett’s esophagus, which is a pre-malignant change in the lining membrane of the esophagus, a cause of esophageal cancer. For more information on Heartburn, its causes and possible cures, visit www.heartburnhelp.com.
Depression. Seriously overweight persons face constant challenges to their emotions: repeated failure with dieting, disapproval from family and friends, sneers and remarks from strangers. They often experience discrimination at work, cannot fit comfortably in theatre seats, or ride in a bus or plane.
Infertility. The inability or diminished ability to produce offspring.
Urinary stress incontinence. A large, heavy abdomen and relaxation of the pelvic muscles, especially associated with the effects of childbirth, may cause the valve on the urinary bladder to be weakened, leading to leakage of urine with coughing, sneezing, or laughing.
Menstrual irregularities. Morbidly obese individuals often experience disruptions of the menstrual cycle, including interruption of the menstrual cycle, abnormal menstrual flow and increased pain associated with the menstrual cycle.
Answering this question may give you the courage you need to take the first step. Below are tools you can use to determine if you are morbidly obese and potentially a candidate for weight loss surgery.
There are several medically accepted criteria for defining morbid obesity. You are likely morbidly obese if you are:

Our Frequently Asked Questions section refers to United States-based generally standard and accepted practices. As always, please check with your healthcare provider to determine their practices, guidelines and what they recommend for you.
Preparation for Surgery
What are the routine tests before surgery?
Certain basic tests are done prior to surgery: a Complete Blood Count (CBC), Urinalysis, and a Chemistry Panel, which gives a readout of about 20 blood chemistry values. Often a Glucose Tolerance Test is done to evaluate for diabetes, which is very common in overweight persons. All patients but the very young get a chest X-ray and an electrocardiogram. Women may have a vaginal ultrasound to look for abnormalities of the ovaries or uterus. Many surgeons ask for a gallbladder ultrasound to look for gallstones. Other tests, such as pulmonary function testing, echocardiogram, sleep studies, GI evaluation, cardiology evaluation, or psychiatric evaluation, may be requested when indicated.
What is the purpose of all these tests?
An accurate assessment of your health is needed before surgery. The best way to avoid complications is to never have them in the first place. It is important to know if your thyroid function is adequate since hypothyroidism can lead to sudden death post-operatively. If you are diabetic, special steps must be taken to control your blood sugar. Because surgery increases cardiac stress, your heart will be thoroughly evaluated. These tests will determine if you have liver malfunction, breathing difficulties, excess fluid in the tissues, abnormalities of the salts or minerals in body fluids, or abnormal blood fat levels.
Why do I have to have a GI Evaluation?
Patients who have significant gastrointestinal symptoms such as upper abdominal pain, heartburn, belching sour fluid, etc., may have underlying problems such as a hiatal hernia, gastroesophageal reflux or peptic ulcer. For example, many patients have symptoms of reflux. Up to 15% of these patients may show early changes in the lining of the esophagus, which could predispose them to cancer of the esophagus. It is important to identify these changes so a suitable surveillance or treatment program can be planned.
Why do I have to have a Sleep Study?
The sleep study detects a tendency for abnormal stopping of breathing, usually associated with airway blockage when the muscles relax during sleep. This condition is associated with a high mortality rate. After surgery, you will be sedated and will receive narcotics for pain, which further depress normal breathing and reflexes. Airway blockage becomes more dangerous at this time. It is important to have a clear picture of what to expect and how to handle it.
Why do I have to have a Psychiatric Evaluation?
The most common reason a psychiatric evaluation is ordered is that your insurance company may require it. Most psychiatrists will evaluate your understanding and knowledge of the risks and complications associated with weight loss surgery and your ability to follow the basic recovery plan.
What impact do my medical problems have on the decision for surgery, and how do the medical problems affect risk?
Medical problems, such as serious heart or lung problems, can increase the risk of any surgery. On the other hand, if they are problems that are related to the patient’s weight, they also increase the need for surgery. Severe medical problems may not dissuade the surgeon from recommending gastric bypass surgery if it is otherwise appropriate, but those conditions will make a patient’s risk higher than average.
If I want to undergo a gastric bypass, how long do I have to wait?
New evaluation appointments are usually booked 4-8 months in advance. Once a patient is seen, if the surgeon and patient agree it is appropriate, the operation can usually be scheduled within 8 weeks. Why so long? There is more need for weight loss surgery than there are qualified bariatric surgeons.
What can I do before the appointment to speed up the process of getting ready for surgery?
Why does it take so long to get insurance approval?
After your telephone interview consultation is completed, it usually takes your doctor 1-2 days to send a letter to your insurance carrier to start the approval process. The time it takes to get an answer can vary from about 3-4 weeks or longer if you are not persistent in your follow-up. Most treatment centers have insurance analysts who will follow up regularly on approval requests. It may be helpful for you to call the claims service of your insurance company about a week after your letter is submitted and ask about the status of your request.
How can they deny insurance payment for a life-threatening disease?
Payment may be denied because there may be a specific exclusion in your policy for obesity surgery or “treatment of obesity.” Such an exclusion can often be appealed when the surgical treatment is recommended by your surgeon or referring physician as the best therapy to relieve life-threatening obesity-related health conditions, which usually are covered.
Insurance payment may also be denied for lack of “medical necessity.” A therapy is deemed to be medically necessary when it is needed to treat a serious or life-threatening condition. In the case of morbid obesity, alternative treatments – such as dieting, exercise, behavior modification, and some medications – are considered to be available. Medical necessity denials usually hinge on the insurance company’s request for some form of documentation, such as 1 to 5 years of physician-supervised dieting or a psychiatric evaluation, illustrating that you have tried unsuccessfully to lose weight by other methods.
What can I do to help the process?
Gather all the information (diet records, medical records, medical tests) your insurance company may require. This reduces the likelihood of a denial for failure to provide “necessary” information. Letters from your personal physician and consultants attesting to the “medical necessity” of treatment are particularly valuable. When several physicians report the same findings, it may confirm a medical necessity for surgery.
When the letter is submitted, call your carrier regularly to ask about the status of your request. Your employer or human relations/personnel office may also be able to help you work through unreasonable delays.
Does Laparoscopic Surgery decrease the risk?
No. Laparoscopic operations carry the same risk as the procedure performed as an open operation. The benefits of laparoscopy are typically less discomfort, shorter hospital stay, earlier return to work and reduced scarring.
Will I have a lot of pain?
Every attempt is made to control pain after surgery to make it possible for you to move about quickly and become active. This helps avoid problems and speeds recovery. Often several drugs are used together to help manage your post-surgery pain. While you are still in the hospital, a Patient Controlled Analgesia (PCA), which allows you to give yourself a dose of pain medicine on demand, may be used by your physician. Various methods of pain control, depending on your type of surgical procedure, are available. Ask your surgeon about other pain management options.
How long do I have to stay in the hospital?
As long as it takes to be self-sufficient. Although it can vary, the hospital stay (including the day of surgery) can be 1-2 days for a laparoscopic band, 2-3 days for a laparoscopic gastric bypass, and 5-7 days for an open gastric bypass.
Will the doctor leave a drain in after surgery?
Most patients will have a small tube to allow drainage of any accumulated fluids from the abdomen. This is a safety measure, and it is usually removed a few days after the surgery. Generally, it produces no more than minor discomfort.
If I have surgery, what can I expect when I wake up in the recovery room?
Some doctors will provide a Patient Controlled Analgesia (PCA) or a self-administered pain management system, to help control pain. Others prefer to use an infusion pump that provides a local anesthetic in the surgical site to control pain without the side effects of narcotics. As with any major surgery, you are in danger of death from a blood clot or other surgical side effects. Statistically, the risk of death during these procedures is less than 1 percent. Your doctors will have assessed you for risks and prepared accordingly.
All abdominal operations carry the risks of bleeding, infection in the incision, thrombophlebitis of legs (blood clots), lung problems (pneumonia, pulmonary embolisms), strokes or heart attacks, anesthetic complications, and blockage or obstruction of the intestine. These risks are greater in morbidly obese patients.
How soon will I be able to walk?
Almost immediately after surgery doctors will require you to get up and move about. Patients are asked to walk or stand at the bedside on the night of surgery, take several walks the next day and thereafter. On leaving the hospital, you may be able to care for all your personal needs, but will need help with shopping, lifting and with transportation.
How soon can I drive?
For your own safety, you should not drive until you have stopped taking narcotic medications and can move quickly and alertly to stop your car, especially in an emergency. Usually this takes 7-14 days after surgery.
The Hospital Stay
What is done to minimize the risk of deep vein thrombosis/pulmonary embolism or DVT/PE?
Because a DVT originates on the operating table, therapy begins before a patient goes to the operating room. Generally, patients are treated with sequential leg compression stockings and given a blood thinner prior to surgery. Both of these therapies continue throughout your hospitalization. The third major preventive measure involves getting the patient moving and out of bed as soon as possible after the operation to restore normal blood flow in the legs.
What should I bring with me to the hospital?
Basic toiletries (comb, toothbrush, etc.) and clothing may be provided by the hospital, but most people prefer to bring their own. Choose clothes for your stay that are easy to put on and take off. Because of your incision, your clothes may become stained by blood or other body fluids. Other ideas:
What’s so important about exercise?
When you have a weight loss surgery procedure, you lose weight because the amount of food energy (calories) you are able to eat is much less than your body needs to operate. It has to make up the difference by burning reserves or unused tissues. Your body will tend to burn any unused muscle before it begins to burn the fat it has saved up. If you do not exercise daily, your body will consume your unused muscle, and you will lose muscle mass and strength. Daily aerobic exercise for 20 minutes will communicate to your body that you want to use your muscles and force it to burn the fat instead.
What is the right amount of exercise after weight loss surgery?
Many patients are hesitant about exercising after surgery, but exercise is an essential component of success after surgery. Exercise actually begins on the afternoon of surgery – the patient must be out of bed and walking. The goal is to walk further on the next day, and progressively further every day after that, including the first few weeks at home. Patients are often released from medical restrictions and encouraged to begin exercising about two weeks after surgery, limited only by the level of wound discomfort. The type of exercise is dictated by the patient’s overall condition. Some patients who have severe knee problems can’t walk well, but may be able to swim or bicycle. Many patients begin with low stress forms of exercise and are encouraged to progress to more vigorous activity when they are able.
Can I get pregnant after weight loss surgery?
It is strongly recommended that women wait at least one year after the surgery before a pregnancy. Approximately one year post-operatively, your body will be fairly stable (from a weight and nutrition standpoint) and you should be able to carry a normally nourished fetus. You should consult your surgeon as you plan for pregnancy.
What if I have had a previous weight loss surgical procedure and I’m now having problems?
Contact your original surgeon – he or she is most familiar with your medical history and can make recommendations based on knowledge of your surgical procedure and body.
What happens to the lower part of the stomach that is bypassed?
In some surgical procedures, the stomach is left in place with intact blood supply. In some cases it may shrink a bit and its lining (the mucosa) may atrophy, but for the most part it remains unchanged. The lower stomach still contributes to the function of the intestines even though it does not receive or process food – it makes intrinsic factor, necessary to absorb Vitamin B12 and contributes to hormone balance and motility of the intestines in ways that are not entirely known. In the BPD procedures, some portion of the stomach is completely removed.
How big will my stomach pouch really be in the long run?
This can vary by surgical procedure and surgeon. In the Roux-en-Y gastric bypass, the stomach pouch is created at one ounce or less in size (15-20cc). In the first few months it is rather stiff due to natural surgical inflammation. About 6-12 months after surgery, the stomach pouch can expand and will become more expandable as swelling subsides. Many patients end up with a meal capacity of 3-7 ounces.
What will the staples do inside my abdomen? Is it okay in the future to have an MRI test? Will I set off metal detectors in airports?
The staples used on the stomach and the intestines are very tiny in comparison to the staples you will have in your skin or staples you use in the office. Each staple is a tiny piece of stainless steel or titanium so small it is hard to see other than as a tiny bright spot. Because the metals used (titanium or stainless steel) are inert in the body, most people are not allergic to staples and they usually do not cause any problems in the long run. The staple materials are also non-magnetic, which means that they will not be affected by MRI. The staples will not set off airport metal detectors.
What if I’m not hungry after surgery?
It’s normal not to have an appetite for the first month or two after weight loss surgery. If you are able to consume liquids reasonably well, there is a level of confidence that your appetite will increase with time.
Is there any difficulty in taking medications?
Most pills or capsules are small enough to pass through the new stomach pouch. Initially, your doctor may suggest that medications be taken in liquid form or crushed.
Will I be able to take oral contraception after surgery?
Most patients have no difficulty in swallowing these pills.
Is sexual activity restricted?
Patients can return to normal sexual intimacy when wound healing and discomfort permit. Many patients experience a drop in desire for about 6 weeks.
Is there a difference in the outcome of surgery between men and women?
Both men and women generally respond well to this surgery. In general, men lose weight slightly faster than women do.
Will I be asked to stop smoking?
Patients are encouraged to stop smoking at least one month before surgery.
If I continue to smoke, what happens?
Smoking increases the risk of lung problems after surgery, can reduce the rate of healing, increases the rates of infection, and interferes with blood supply to the healing tissues.
How can I know that I won’t just keep losing weight until I waste away to nothing?
Patients may begin to wonder about this early after the surgery when they are losing 20-40 pounds per month, or maybe when they’ve lost more than 100 pounds and they’re still losing weight. Two things happen to allow weight to stabilize. First, a patient’s ongoing metabolic needs (calories burned) decrease as the body sheds excess pounds. Second, there is a natural progressive increase in calorie and nutrient intake over the months following weight loss surgery. The stomach pouch and attached small intestine learn to work together better, and there is some expansion in pouch size over a period of months. The bottom line is that, in the absence of a surgical complication, patients are very unlikely to lose weight to the point of malnutrition.
What can I do to prevent lots of excess hanging skin?
Many people heavy enough to meet the surgical criteria for weight loss surgery have stretched their skin beyond the point from which it can “snap back.” Some patients will choose to have plastic surgery to remove loose or excess skin after they have lost their excess weight. Insurance generally does not pay for this type of surgery (often seen as elective surgery). However, some do pay for certain types of surgery to remove excess skin when complications arise from these excess skin folds. Ask your surgeon about your need for a skin removal procedure.
Will exercise help with excess hanging skin?
Exercise is good in so many other ways that a regular exercise program is recommended. Unfortunately, most patients may still be left with large flaps of loose skin.
Will I be miserably hungry after weight loss surgery since I’m not eating much?
Most patients say no. In fact, for the first 4-6 weeks patients have almost no appetite. Over the next several months the appetite returns, but it tends not to be a ravenous “eat everything in the cupboard” type of hunger.
What if I am really hungry?
This is usually caused by the types of food you may be consuming, especially starches (rice, pasta, potatoes). Be absolutely sure not to drink liquid with food since liquid washes food out of the pouch.
Will I have to change my medications?
Your doctor will determine whether medications for blood pressure, diabetes, etc., can be stopped when the conditions for which they are taken improve or resolve after weight loss surgery. For meds that need to be continued, the vast majority can be swallowed, absorbed and work the same as before weight loss surgery. Usually no change in dose is required. Two classes of medications that should be used only in consultation with your surgeon are diuretics (fluid pills) and NSAIDs (most over-the-counter pain medicines). NSAIDs (ibuprofen, naproxen, etc.) may create ulcers in the small pouch or the attached bowel. Most diuretic medicines make the kidneys lose potassium. With the dramatically reduced intake experienced by most weight loss surgery patients, they are not able to take in enough potassium from food to compensate. When potassium levels get too low, it can lead to fatal heart problems.
What is a hernia and what is the probability of an abdominal hernia after surgery?
A hernia is a weakness in the muscle wall through which an organ (usually small bowel) can advance. Approximately 20% of patients develop a hernia. Most of these patients require a repair of the herniated tissue. The use of a reinforcing mesh to support the repair is common.
Is blood transfusion required?
Infrequently: If needed, it is usually given after surgery to promote healing.
What is phlebitis and is it preventable?
Undesired blood clotting in veins, especially of the calf and pelvis. It is not completely preventable, but preventive measures will be taken, including:
Will I lose hair after surgery? How can I prevent it?
Many patients experience some hair loss or thinning after surgery. This usually occurs between the fourth and the eighth month after surgery. Consistent intake of protein at mealtime is the most important prevention method. Also recommended are a daily zinc supplement and a good daily volume of fluid intake.
Does hair growth recover?
Most patients experience natural hair regrowth after the initial period of loss.
What are adhesions and do they form after this surgery?
Adhesions are scar tissues formed inside the abdomen after surgery or injury. Adhesions can form with any surgery in the abdomen. For most patients, these are not extensive enough to cause problems.
What is the “Candida Syndrome?”
Some patients have a type of yeast present on the surface of their skin, intestine or vagina at the time of surgery. This leads to overgrowth in certain circumstances. A whitish coating may occur on the tongue or throat. This syndrome is associated with a frothy mucous, nausea, difficulty swallowing, sore throat, loss of taste and appetite, and occasionally abdominal bloating and diarrhea.
What causes it to appear?
It is promoted by the use of most antibiotics and some other medications, by stress, by reduced immune response, and by diabetes.
Can it be cured?
There are several effective medications now available for treating the overgrowth of Candida.
What is sleep apnea (SA)?
It is the interruption of the normal sleep pattern associated with repeated delays in breathing. Sleep apnea often shows rapid improvement after surgery. In most patients, there is a complete resolution of symptoms by six months following surgery.
How long will I be off of solid foods after surgery?
Most surgeons recommend a period of four weeks or more without solid foods after surgery. A liquid diet, followed by semi-solid foods or pureed foods, may be recommended for a period of time until adequate healing has occurred. Your surgeon will provide you with specific dietary guidelines for the best post-surgical outcome.
What are the best choices of protein?
Eggs, low-fat cheese, low-fat cottage cheese, tofu, fish, other seafood, chicken (dark meat), turkey (dark meat).
Why drink so much water?
When you are losing weight, there are many waste products to eliminate, mostly in the urine. Some of these substances tend to form crystals, which can cause kidney stones. A high water intake protects you and helps your body to rid itself of waste products efficiently, promoting better weight loss. Water also fills your stomach and helps to prolong and intensify your sense of satisfaction with food. If you feel a desire to eat between meals, it may be because you did not drink enough water in the hour before.
What is Dumping Syndrome?
Eating sugars or other foods containing many small particles when you have an empty stomach can cause dumping syndrome in patients who have had a gastric bypass or BPD where the stomach pylorus is removed. Your body handles these small particles by diluting them with water, which reduces blood volume and causes a shock-like state. Sugar may also induce insulin shock due to the altered physiology of your intestinal tract. The result is a very unpleasant feeling: you break out in a cold clammy sweat, turn pale, feel “butterflies” in your stomach, and have a pounding pulse. Cramps and diarrhea may follow. This state can last for 30-60 minutes and can be quite uncomfortable – you may have to lie down until it goes away. This syndrome can be avoided by not eating the foods that cause it, especially on an empty stomach. A small amount of sweets, such as fruit, can sometimes be well tolerated at the end of a meal.
Is there a problem with consuming milk products?
Milk contains lactose (milk sugar), which is not well digested. This sugar passes through undigested until bacteria in the lower bowel act on it, producing irritating byproducts as well as gas. Depending on individual tolerance, some persons find even the smallest amount of milk can cause cramps, gas and diarrhea.
Why can’t I snack between meals?
Snacking, nibbling or grazing on foods, usually high-calorie and high-fat foods, can add hundreds of calories a day to your intake, defeating the restrictive effect of your operation. Snacking will slow down your weight loss and can lead to regain of weight.
Why can’t I eat red meat after surgery?
You can, but you will need to be very careful, and we recommend that you avoid it for the first several months. Red meats contain a high level of meat fibers (gristle) which hold the piece of meat together, preventing you from separating it into small parts when you chew. The gristle can plug the outlet of your stomach pouch and prevent anything from passing through, a condition that is very uncomfortable.
How can I be sure I am eating enough protein?
40 to 65 grams a day are generally sufficient. Check with your surgeon to determine the right amount for your type of surgery.
Is there any restriction of salt intake?
No, your salt intake will be unchanged unless otherwise instructed by your primary care physician.
Will I be able to eat “spicy” foods or seasoned foods?
Most patients are able to enjoy spices after the initial 6 months following surgery.
Will I be allowed to drink alcohol?
You will find that even small amounts of alcohol will affect you quickly. It is suggested that you drink no alcohol for the first year. Thereafter, with your physician’s approval, you may have a glass of wine or a small cocktail.
Will I need supplemental vitamins?
B12 injections are sometimes suggested once a month for the first year and every six months thereafter. B12 may also be taken orally or sublingually (under the tongue) by many patients.
What vitamins will I need to take after surgery?
Most surgeons recommend a daily multivitamin for the rest of your life.
Is it important to take calcium, iron, trace elements or female hormone replacements?
Some patients require these supplements, but your need for these can be determined by your surgeon.
Do I meet with a nutritionist before and after surgery?
Most surgeons require patients to consult with a nutritionist before surgery. Counseling after surgery is available on an individual basis as needed or required by your physician.
Will I get a copy of suggested eating patterns and food choices after surgery?
Surgeons provide patients with materials that clearly outline their expectations regarding diet and compliance to guidelines for the best outcome based on your surgical procedure. After surgery, health and weight loss are highly dependent on patient compliance with these guidelines. You must do your part by restricting high-calorie foods, by avoiding sugar, snacks and fats, and by strictly following the guidelines set by your surgeon.
What is the youngest age for which weight loss surgery is recommended?
Generally accepted guidelines from the American Society for Bariatric Surgery and the National Institutes of Health indicate surgery only for those 18 years of age and older. Surgery has been performed on patients 16 and younger. There is a real concern that young patients may not have reached full developmental or emotional maturity to make this type of decision. It is important that young weight loss surgery patients have a full understanding of the lifelong commitment to the altered eating and lifestyle changes necessary for success.
What is the oldest patient for whom weight loss surgery is recommended?
Patients over 65 require very strong indications for surgery and must also meet stringent Medicare criteria. The risk of surgery in this age group is increased, and the benefits, in terms of reduced risk of mortality, are reduced.
