Gastric Bypass Surgery

gastric-bypassGastric bypass surgery is the most frequently performed weight loss surgery in South Florida and the rest of the United States. You may also hear the gastric bypass referred to as the Roux-en-Y gastric bypass. The procedure reduces the amount of food that can be eaten at one time in a process called restriction and also incorporates malabsorption to reduce the number of calories absorbed into the body from your food.

Because of this two-fold approach, gastric bypass averages a slightly better weight loss than both gastric band and gastric sleeve after one year.

The Roux-en-Y Gastric Bypass Surgery

During the Roux-en-Y gastric bypass procedure, a small portion of the stomach is used to create a secondary food pouch that is about the size of an egg. Food passes through this portion of the stomach, greatly reducing stomach capacity. The middle portion of the small intestine is then connected to that smaller pouch.

Bypassing certain portions of the small intestine reduces the absorption of calories and nutrients by the body, further enhancing weight loss efforts.

Unlike the gastric sleeve weight loss surgery, the larger portion of the stomach is not removed during the gastric bypass procedure. By directing the small intestine to the smaller portion of the stomach, patients benefit from reduced stomach capacity without requiring the removal of the remainder of the organ.

Benefits of Gastric Bypass

Gastric bypass surgery has proven highly successful for long-term weight loss in people who are compliant with post-surgical guidelines. It is usually available as a minimally invasive procedure, which reduces bleeding and discomfort and shortens recovery time. Following gastric bypass surgery, there is no requirement for post-operative adjustments as needed following gastric band surgery.

Patients lose an average of 61 percent of their excess weight with gastric bypass surgery, and are often able to maintain most of their weight loss as far as 10 years following surgery.

Gastric bypass surgery is associated with dramatic improvement or total resolution of several obesity related diseases, including:

  • Gastroesophageal Reflux Disease (GERD)
  • Heart disease
  • Hypertension (High Blood Pressure)
  • Severe sleep apnea
  • Type-2 diabetes
  • Stroke
