Cosmetic weight loss surgery or bariatric surgery is gaining popularity due to increasing knowledge of using cosmetic surgery as a technique for targetted or quick weight loss.

Patients may opt for a cosmetic weight loss surgery out of reshaping their body shape or simply to improve their health and escape from severe obesity.

There are basically three types of cosmetic weight loss surgery :-

There are the restrictive surgical procedures like the lap band surgery to make the stomach smaller and thus limiting food consumption.

Then there are the malabsorptive surgeries to shorten the intestine that comes in contact with food so that the body absorbs less calories from the food consumed.

Finally, there are surgeries that combine both restrictive and malasorptive surgeries.

Restrictive surgeries encourage the patient to lose weight in two ways. Firstly the surgeries reduce the amount of food consumed. The stomach is shrunk by creating a small pouch at the top of where food enters and therefore less food is consumed by the patients. Restrictive weight loss surgery also make patients feel full longer because the lower outlet of the pouch is made smaller so that food empties slowly.
