According to the American Society for Metabolic and Bariatric Surgery and the National Institutes of Health, Roux-en-Y gastric bypass is the current gold standard procedure for weight-loss surgery. It is one of the most frequently performed weight-loss procedures in the United States. This surgery combines restrictive and malabsorptive aspects to offer the greatest weight loss and disease resolution potential of any of the common bariatric procedures.
How it works:
Gastric bypass surgery is a minimally invasive procedure in which the surgeon makes five or six small ½- to 1-inch incisions in the abdomen. Medical devices called trocars are fitted into the incisions to guide the surgeon’s tools into the abdomen. The surgeon can see the abdominal cavity with the help of a laparoscopic camera, which projects the image of the abdomen onto screens mounted above the operating table.
In the first part of the surgery, restriction is accomplished by cutting away approximately 80 percent of the stomach. The procedure reduces the stomach to about the size of a golf ball. After the procedure, the stomach can receive only a small amount of food. The portion of the stomach that is cut away remains in the abdomen; however, it will no longer accept food. The new, smaller stomach reduces the amount of food that a patient can eat at any given sitting, and in turn, restricts the number of calories he or she can consume.
The second part of the procedure is the bypassing of the duodenum, also known as the small intestine. In bypassing part of the small intestine, fewer calories are absorbed by the sensitive intestinal walls. This process is known as malabsorption.
With recent discoveries in research, the above changes in anatomy also produce a significant change in the levels of hormones created by the stomach and intestines, called gut hormones. These changes cause a decrease in hunger while increasing metabolic rate and sensitivity to insulin. This results in losing fat and improving diabetes.
