The basic rules are simple and easy to follow:
- Immediately after surgery, your doctor will provide you with special dietary guidelines. You will need to follow these guidelines closely. Many surgeons begin patients with liquid diets, moving to semi-solid foods and later, sometimes weeks or months later, solid foods can be tolerated without risk to the surgical procedure performed. Allowing time for proper healing of your new stomach pouch is necessary and important.
- When able to eat solids, eat 2-3 meals per day, no more. Protein in the form of lean meats (chicken, turkey, fish) and other low-fat sources should be eaten first. These should comprise at least half the volume of the meal eaten. Foods should be cooked without fat and seasoned to taste. 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.
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.
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.
If you are a woman you will have an increased chance of becoming pregnant. It is difficult to maintain a healthy pregnancy during the rapid weight loss phase (first year after surgery for bypass patients). If you are planning to have a gastric bypass, we recommend that you postpone pregnancy plans for at least one year after surgery or until your weight is stable.
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.
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.
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.

8. 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.
It's normal not to have an appetite for the first few months 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.
During the first few months after surgery we recommend patients crush their medications or take them in a liquid form. Medications that cannot be crushed are long acting medications usually designated by "XR" or "CR" after the name of the medication. These will be converted to the shorter released medication which can be crushed. There are some psychiatric medications (such as cymbalta) that cannot be crushed and are too big to take in the immediate post operative period. Before surgery, please check with your PCP and mental health provider, and/or your pharmacist, to see which medications can and cannot be crushed.
Patients can return to normal sexual intimacy when wound healing and discomfort permit. Many patients experience a drop in desire for about 6 weeks.
Both men and women generally respond well to this surgery. In general, men lose weight slightly faster than women do.
We require patients to stop smoking and be tobacco free for at least two months prior to their surgery. Smoking after weight loss surgery can be particularly dangerous, especially after gastric bypass as it can cause ulcers to form that are painful and difficult to treat. Occasionally these ulcers can perforate, requiring emergency surgery.
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.
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, such as recurrent yeast infections that are not well treated with medications. Ask your surgeon about your need for a skin removal procedure.
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.
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 bad type of hunger.
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.
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.
A hernia is a weakness in the muscle wall through which an organ (usually small bowel) can advance. When we were doing weight loss surgery primarily opne (through a large incision), approximately 20% of patients developed a hernia. Now that we do virtually all procedures laparoscopically, the hernia rate is less than 1%.
Infrequently: If needed, it is usually given immediately after surgery.
Undesired blood clotting in veins, especially of the calf and pelvis. It is not completely preventable, but preventive measures will be taken, including:
- Early ambulation
- Blood thinners (heparin shots given to you before the operation and three times a day while you are in the hospital)
- Pulsatile boots
Many patients experience some hair loss or thinning after surgery. This usually occurs between the third 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. An oral supplement, biotin, has been shown to help some patients.
Most patients experience natural hair regrowth after the initial period of loss.
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, especially when the procedure is performed laparoscopically.
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.
