Gastric Bypass is the most common form of weight loss surgery in the United States because it results in reliable weight loss with acceptable risks and minimal side effects. In gastric bypass surgery, the surgeon staples off a large section of the stomach, leaving a tiny pouch.
Patients simply can't eat as much as they did before surgery, because this small pouch can only accommodate a few ounces of food at a time, and they subsequently lose weight. In addition, a major portion of the stomach and a small portion of the intestine are bypassed to reduce moderately the absorption of calories and nutrients.
The amount of weight loss with gastric bypass depends on many factors. Most lose 60 to 70% of their excess body weight within 12 to 18 months of surgery. Recent large published series have shown weight loss maintenance beyond 10 years.
Because combined operations (restrictive and malabsorbtive) result in greater weight loss than restrictive operations, they may also be more effective in improving the health problems associated with severe obesity, such as hypertension (high blood pressure), sleep apnea, type 2 diabetes, and osteoarthritis.

Stomach contents move too quickly through the small intestine, causing symptoms such as nausea, bloating, abdominal pain, weakness, sweating, faintness, and sometimes diarrhea after eating.
