- Bariatric surgery is actually a weight-loss surgery that helps you lose weight by making changes in your digestive system. It includes a variety of procedures on people who are obese.
- This surgery involves the use of the gastric band to reduce the size of the stomach or involves removal of a portion of the stomach by sleeve gastrectomy or biliopancreatic diversion with duodenal switch.
- The size of the stomach can also be reduced by resecting and re-routing the small intestine to a small stomach pouch and this process is known as gastric bypass surgery.
- These weight loss surgeries are generally done after you have tried some other ways to lose weight such as following a healthy, balanced diet and doing regular exercise.
- Sleeve gastrectomy is a surgical weight-loss procedure usually performed using an instrument laparoscope.
- In this procedure a large portion of the stomach is removed and with the result, the stomach is reduced to 15 % of its original size.
- This surgical procedure changes the shape of the stomach to sleeve or tube-like structure.
- Originally, Sleeve gastrectomy was performed as a modification to the duodenal switch, a bariatric procedure. Then, later on, it was performed as first part of the surgical procedure on very obese patients in which the risk of performing gastric bypass surgery alone was too large.
- Today, sleeve gastrectomy is the fastest-growing weight loss surgical procedure. This procedure involves a longitudinal resection of the stomach starting from the antrum at the point 5–6 cm from the pylorus and finishing at the fundus close to the cardia.

Dietary adjustments after bariatric surgery-
After bariatric surgery, you have to make some dietary adjustments. As this weight loss surgery makes your stomach smaller by closing off most of your stomach with staples, you need to take small meals now. Your body will not absorb all the calories from the food which you eat. You should not drink fluids while eating. You can drink water or other fluids at least 30 minutes before or after eating. Usually, it doesn’t take a long time for most people to make adjustments to their dietary habits.
