Obesity or heavy weight is a common problem all over the world. More than 38 per cent of the global population is overweight or obese due to a poor lifestyle of the people or sometimes genetic problems. The high prevalence of the problem does not make it any less harmful. Obesity makes your body prone to various chronic diseases, occasionally life-threatening as well.

Thus, advancements in the healthcare industry have introduced bariatric surgery. It is a group of surgical procedures designed to help people lose weight by altering their digestive system. The surgery is performed by highly trained, expert surgeons at the specialist Bariatric Surgery Hospital in India, Park Hospital, to help people avoid various medical conditions associated with heavy weight and improve the overall quality of life of the patients.

Here's an overview of the different types of bariatric surgery and their pros and cons, according to Park Hospital, the best bariatric surgeon in India.


Gastric Bypass Surgery (Roux-en-Y Gastric Bypass)

Gastric bypass surgery, also called Roux-en-Y gastric bypass, is a kind of bariatric surgery that separates the stomach into two parts, including the stomach pouch.
