The gastric bypass was first developed in the 1960's. It is still one of the most commonly performed weight loss surgery in the USA. The gastric bypass has both a restrictive (small stomach pouch), and a malabsorptive component (part of the small intestine is bypassed causing less food absorption). This results in rapid weight loss and improvement of weight related illnesses. Half of the total weight loss occurs in the first six months after surgery, and like the sleeve gastrectomy, average weight loss is 10 to 12 pounds per month. With aggressive dieting and exercise one can expect further weight loss and some times can achieve an ideal body weight.

The mechanism by which gastric bypass works is complex. A small stomach pouch fills with a small amount of food, satisfying hunger. In addition, the part of the stomach which affects appetite is bypassed leading to a decrease in appetite and food cravings. After surgery, patients experience marked changes in their behavior. Most have a reduction in hunger, tend to enjoy healthier foods and lose a lot of the improper food cravings.

Because the gastric bypass involves cutting, re-routing and bypassing intestines and stomach, the bypass has more risks than the sleeve gastrectomy and the Lap Band. Some of the risks like micronutrients and multivitamin deficiency are life long. Another side effect of the gastric bypass is the dumping syndrome. Heart palpitations, flushing, abdominal pain and diarrhea describe this syndrome. These symptoms occur after eating foods high in sugar. Bypass patients are adviced to avoid foods that are high in sugar. Some patients remain sensitive to sweets for the rest of their lives. Most lose the sensitivity to sweets over time.

Despite the potential risks and side effects, the gastric bypass still is one of the most effective weight loss procedure. When done laparoscopically, in experienced centers with experienced surgeons, gastric bypass patients can achieve excellent weight loss, and resolution of obesity related diseases.
