A gastric bypass is an operation performed on obese people to greatly decrease the size of the stomach, resulting in less food being consumed and fewer calories absorbed. Gastric bypass surgery is a last resort option after diets, exercise, and other therapies have failed, and is a fairly drastic procedure. However it can result in extremely successful and sustained weight loss.
This article on gastric bypass surgery is written by Jackie Griffiths, a freelance journalist who writes health, medical, biological, and pharmaceutical articles for national and international journals, newsletters and web sites.
One person in a hundred will die from obesity surgery so it is not something to go into lightly; on the other hand if these individuals stayed obese they are at greater risk from dying from obesity-related conditions such as heart disease, diabetes, and cancer. A recent study showed that obese people who have obesity surgery are 40% less likely to die over the next seven to ten years than those who do not have the surgery.
However you do it, it’s vital to get your weight down as soon as possible if you are obese.
What is a gastric bypass?
Sometimes known as ‘stomach stapling,’ the gastric bypass operation is recommended to be undertaken for medical reasons rather than cosmetic. During the procedure a small pouch is created at the top of your stomach by sealing off the rest, leaving only a small portion of the stomach open and able to receive food. This is then attached to the small intestine, bypassing the rest of the stomach and a part of your bowel, meaning that not only do you eat much smaller portions and feel full sooner, but you absorb few calories from the food you do eat. On average people tend to lose 60-70% of their excess weight within two years.
