Gastric Bypass vs Gastric Band
Gastric Bypass vs Gastric Band
The term bariatric surgery encompasses many forms of surgery available to assist with weight loss in obese patients. It should be noted that bariatric surgery is recommended only for those who are morbidly obese and suffer from health consequences caused by the obesity. Bariatric surgery is a serious undertaking and requires commitment to be successful. In addition, bariatric surgeries of any kind carry with them the risk of complications and death. This article will explain two forms of bariatric surgery: gastric bypass and gastric band.

People who qualify for either procedure have a body mass index (BMI) of over 40, or have a BMI of 35 and have one or more severe co-morbid conditions: high blood pressure, diabetes, spinal or joint problems, venous thromboembolic disease, obstructive sleep apnea, and other related issues.

Gastric Bypass Surgery

Gastric bypass is the blanket term used for the permanent surgical re-arrangement of the stomach and small intestine. Basically, the stomach is divided into two areas: an upper (small) pouch, about 10% of the size of the entire stomach, and the remaining portion of the stomach. The small intestine is then reattached. The purpose of this procedure is to reduce the amount of food required before the patient feels full, which limits the number of calories consumed each day. Weight is lost fairly quickly, and most patients will lose an average of 65 to 80% of excess weight in the first three and a half years following surgery.

Risks and complications of gastric bypass surgery include (but are not limited to):

  • adverse reaction to anaesthesia which causes death;
  • complications of abdominal surgery such as bowel obstruction, venous thromboembolism, infection, hemorrhage and hernia;
  • complications of gastric bypass such as dumping syndrome, anastomotic ulcer, anastomatic stricture, and anastomatic leakage; and
  • nutritional deficiencies.
