Gastric stapling surgery is a type of weight loss surgery that limits the amount of food a person can eat.
Gastric bypass surgery involves bypassing a part of the small intestine that absorbs nutrients. For this reason, these surgeries are referred to as malabsorptive procedures.
After surgery, you must learn to eat differently: Eat smaller portions; eat slowly and chew your food well, advises the National Institute of Diabetes and Digestive and Kidney Diseases. It's also important to have periodic checkups afterward to ensure that you are getting enough of the vitamins and minerals you need to prevent malnutrition.
