Gastric Bypass Surgery

Gastric bypass surgery uses a combination of restriction and malabsorption to achieve results. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a large portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food; bypassing a portion of the small intestine means the patient's body absorbs fewer calories.

Gastric bypass surgery can be performed laproscopically or robotically. Both methods are minimally invasive and result in less pain and a shorter recovery time for the patient. The patient also experiences less blood loss and less scarring than the patient who undergoes traditional open gastric bypass surgery.

Gastric Bypass Surgery Health Benefits According to Clinical Trials

  • Gastric bypass surgery patients typically lost 61.6% of their excess weight.
  • Gastric bypass surgery resolved type 2 diabetes in 83.8% of patients often within days.
  • Gastric bypass surgery resolved high blood pressure in 75.4% of patients.
  • Gastric bypass surgery lowered high cholesterol in 95% of patients.

Quality of Life

One meta-analysis stated that for bariatric surgery patients who experienced significant weight loss:

  • Overall quality of life improved greatly.
  • Improved physical functioning and appearance were experienced.
  • Improved social and economic opportunities were experienced.

Gastric Bypass Surgery Recovery

One study found that gastric bypass patients were able to:

  • Leave the hospital after two days.
  • Return to work after 21 days.

Potential Concerns Associated with Gastric Bypass Surgery

  • A condition known as dumping syndrome can occur from eating high-fat and high-sugar foods. While it isn't considered a health risk, the results can be very unpleasant and may include vomiting, nausea, weakness, sweating, faintness, and diarrhea.
  • Patients must supplement their diet with a daily multivitamin and calcium. Some patients must take vitamin B12 and/or iron.
  • The stomach, duodenum, and parts of the small intestine cannot be seen easily using x-ray or endoscopy if there are problems after surgery such as ulcers, bleeding, or malignancy.
