Y gastric bypass

Gastric bypass weight loss surgery is a mixed gastric bypass surgery, utilizing both a decrease in stomach size and a partial bypass of the small intestine to limit calorie intake. Gastric bypass is also commonly referred to as "roux-en-y" weight loss surgery.

Patients who have had this procedure feel full much faster, and stay that way for much longer, than is typical. This is because a pouch is created to isolate only a small section of the stomach for the processing of food. In addition, a section of the small intestine is bypassed to reduce the amount of food, and
therefore calories, that can be used by the body.

If you undergo this procedure, you must make radical changes in your food intake and lifestyle in order for the procedure to have the maximum effect. Meals following surgery must be limited to approximately one ounce each; drinking fluids with meals can fill the pouch, too, so you should be mindful that doing so may prevent the intake of solid food. But, because the stomach has the ability to stretch to accommodate food, you can consume larger portions than that over time.
