The gastric bypass, or Roux-en-Y Gastric Bypass, is the oldest and most commonly performed bariatric surgery procedure. It consists of cutting and stapling the stomach to create a smaller pouch while also re-routing the intestines. The gastric bypass weight loss surgery helps patients lose weight by restricting the amount of food a patient can consume, and by creating a malabsorptive effect. We also believe this procedure will recalibrate the body's metabolic set point. The gastric bypass is a reversible procedure and can be revised to another procedure if needed.
Roux-en-Y Gastric Bypass
During the operation, the surgeon will divide the stomach into two parts—the small gastric pouch at the top and the larger disconnected section at the bottom. The small intestine is then divided a few feet from the stomach and brought up to meet the small gastric pouch.
The new, smaller stomach is now about the size of an egg. As a result, patients will feel full faster, thereby eating less. Also, when food bypasses the stomach, this causes fewer calories and nutrients to be absorbed, creating a malabsorptive effect. Additionally, we believe that by diverting food away from the upper part of the intestines (duodenum) will recalibrate the body's metabolism through hormonal mechanisms.
The gastric bypass weight loss surgery takes about 1 hour to perform, and patients can expect to stay at the hospital for 24 to 48 hours after surgery. Depending on the type of work performed, patients will be able to return to work within 2 to 4 weeks from surgery.
Before considering the gastric bypass, it is important to be familiar with the potential risks of bariatric procedures. Risks vary based on the health of the patient.
- Minor wound or skin infection
- Excess / loose skin
- Vomiting or nausea
- Acid reflux (heartburn)
- Changes in bowel habits like constipation, diarrhea, bloating, cramping, or gas
- Gastric ulcer or anastomotic stricture
- Development of gallstones or gallbladder disease
- Nutritional deficiencies as a result of food bypassing the stomach
- Dumping syndrome when high sugar foods move too fast from the stomach to the small intestine
- Internal Bleeding
- Intestinal obstruction
- Blood clots in the legs or lungs
- Internal hernia
- Perforation of stomach/intestine or leakage
A portion of the stomach is removed, intestines are rearranged, and the gallbladder is removed.Duodenal Switch
