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
All patients but the very young get a chest X-ray and an electrocardiogram. Women may have a ultrasound to look for abnormalities of the ovaries or uterus. A ultrasound to look for gallstones. Other tests, such as pulmonary function testing, echocardiogram, sleep studies, GI evaluation or cardiology 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.

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.


Insurance Issues

Is this surgery benefited by insurance policies?
Usually it depends upon the policy of the insurance companies. Some patients do not get the re imbursement for the procedure. However every attempt would be made from our side to benefit your claim.


Surgery

How is weight loss surgery different than liposuction?
Weight Loss Surgery is major surgery involving the gastrointestinal tract. The stomach and intestines are modified so that less food can be consumed or absorbed, which leads to a substantial loss of weight that can be maintained for years. Liposuction is a form of cosmetic surgery in which areas of the body are reshaped or resculpted by removing excess amounts of fat in those areas. The purpose of liposuction is not to produce weight loss

Why should I consider WLS?
Because it works! Surgical treatment for obesity is the ONLY treatment that reliably produces significant and sustained weight loss. People with clinically severe obesity are at great risk for developing many associated medical conditions. Research has shown that surgical treatment results in significant weight loss and improvement in most problems associated with obesity. Surgical treatment for clinically severe obesity has been endorsed by the National Institutes of Health & the World Health Organization

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.

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 sleeve, and 3-5 days for an laparoscopic gastric bypass.

Will the doctor leave a drain in after surgery?
Most patients do not require a tube but some patient may need it 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.

How soon will I be able to walk?

Almost immediately after surgery,you are required 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.

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.


Life After Surgery

What do I need to do to be successful after surgery?
The basic rules are simple and easy to follow:
Immediately after surgery, we shall  provide you with special dietary guidelines. You will need to follow these guidelines closely.
When able to eat solids, eat 2-3 meals per day, no more
Avoid sauces, gravies, butter, margarine, mayonnaise and junk foods.
Never eat between meals. Do not drink flavored beverages, even diet soda, between meals.
Drink 2-3 quarts or more of water each day. Water must be consumed slowly, 1-2 mouthfuls at a time, due to the restrictive effect of the operation.
Exercise aerobically every day for at least 20 minutes (one-mile brisk walk, bike riding, stair climbing, etc.). Weight/resistance exercise can be added 3-4 days per week, as instructed by your doctor.
   
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 & half 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.

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.

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.

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.

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 medicines 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.

Is blood transfusion required?
Infrequently: If needed, it is usually given after surgery to promote healing.

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.
   
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 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.


Diet

How long will I be off of solid foods after surgery?
We recommend a period of two 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. We shall 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.

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 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.
Duping doesn’t occur after Gastric Sleeve.

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.

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 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?

A daily multivitamin for the rest of your life is required after Gastric Bypass surgery.
After Gastric Sleeve no supplements are required.

Is it important to take calcium, iron, trace elements ?

Some patients require these supplements, but your need for these can be determined by our team.

Do I meet with a nutritionist before and after surgery?

Our team has a dietician with us who looks after all our patients and takes care of the preoperative and postoperative diet.

Will I get a copy of suggested eating patterns and food choices after surgery?
We 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.


General

What is the youngest age for which weight loss surgery is recommended?
Generally accepted guidelines from 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. 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.
   
Can Weight Loss Surgery prolong my life?

There is good evidence from scientific research that if you have Type 2 diabetes (or other serious obesity-related health conditions), are at least 100 lbs. over ideal body weight, and are able to comply with lifestyle changes (daily exercise and low-fat diet), then weight loss surgery may significantly prolong your life.

Can weight loss surgery help other physical conditions?

According to current research, weight loss surgery can improve or resolve associated health conditions.
