As with any major surgery, gastric bypass and other weight-loss surgeries pose potential health risks, both in the short term and long term.
Risks associated with the surgical procedure are similar to any abdominal surgery and can include:. In the weeks leading up to your surgery, you may be required to start a physical activity program and to stop any tobacco use. Right before your procedure, you may have restrictions on eating and drinking and which medications you can take.
Now is a good time to plan ahead for your recovery after surgery. For instance, arrange for help at home if you think you'll need it. Gastric bypass surgery is done in the hospital. Depending on your recovery, your hospital stay is typically one to two days but may last longer. You will be given general anesthesia before your surgery begins. Anesthesia is medicine that keeps you asleep and comfortable during surgery.
The specifics of your gastric bypass depend on your individual situation and the doctor's practices. Some surgeries are done with traditional large open incisions in your abdomen.
However, most are performed laparoscopically, which involves inserting instruments through multiple small incisions in the abdomen.
After making the incisions with the open or laparoscopic technique, the surgeon cuts across the top of your stomach, sealing it off from the rest of your stomach. The resulting pouch is about the size of a walnut and can hold only about an ounce of food.
Normally, your stomach can hold about 3 pints of food. Then, the surgeon cuts the small intestine and sews part of it directly onto the pouch. Food then goes into this small pouch of stomach and then directly into the small intestine sewn to it. Food bypasses most of your stomach and the first section of your small intestine, and instead enters directly into the middle part of your small intestine. Surgery usually takes a few hours.
After surgery, you awaken in a recovery room, where medical staff monitors you for any complications. Immediately after gastric bypass surgery, you may have liquids but no solid food as your stomach and intestines begin to heal. You'll then follow a special diet plan that changes slowly from liquids to pureed foods. After that, you can eat soft foods, then move on to firmer foods as your body is able to tolerate them.
You may have many restrictions or limits on how much and what you can eat and drink. Your doctor will recommend you take vitamin and mineral supplements after surgery, including a multivitamin with iron, calcium and vitamin B You'll also have frequent medical checkups to monitor your health in the first several months after weight-loss surgery.
You may need laboratory testing, bloodwork and various exams. You may experience changes as your body reacts to the rapid weight loss in the first three to six months after gastric bypass, including:. In Roux-en-Y gastric bypass, the surgeon creates a small pouch at the top of the stomach. The pouch is the only part of the stomach that receives food. This greatly limits the amount that you can comfortably eat and drink at one time. Specialties Learn about the medical and surgical specialties and sub-specialties we provide.

In , Molina described the gastric segmentation procedure, in which a Dacron vascular graft was placed around the upper stomach. This balloon was connected to a small reservoir that is placed under the skin of the abdomen through which the diameter of the band can be adjusted.
Inflation of the balloon functionally tightens the band and thereby increases weight loss, while deflation of the balloon loosens the band and reduces weight loss. These bands can be inserted laparoscopically, thereby reducing the complications and discomfort of an open procedure. None have yet been shown clearly to be superior to the other.
Since these procedures do not involve an intestinal bypass, laparoscopic adjustable gastric banding LAGB is a procedure which induces weight loss solely through the restriction of food intake. For optimal results, strict patient compliance and frequent follow-up for band adjustments are required. The mortality risk with the LAGB is about 0. The LAGB is safe and has a low rate of life-threatening complications.
An improvement in weight-related comorbidities has been observed, including Type II diabetes mellitus, dyslipidemia, sleep apnea, gastroesophageal reflux, hypertension, and asthma. However, compared to the gastric bypass, the impact on co-morbidities appears to be somewhat less favorable.
While some studies have documented weight loss equal to RYGBP with fewer complications, other groups have had disappointing outcomes. Some studies document a substantial number of patients who have required re-operation for long-term complications of the adjustable band such as for port problems, erosions and slippage, or inadequate weight loss.
