Vejthani Hospital provides state-of-the-art Gastric Bypass Surgery using modern bariatric methods and internationally recognised treatment techniques. The 1994established and JCIaccredited hospital is located in Bangkok, Thailand, and has 263 beds, enabling it to provide more comprehensive bariatric treatment for both local and international patients.

The Gastric Bypass procedure encourages weight loss by limiting stomach size and altering how food moves through the digestive tract. This surgery is recommended to be performed for patients with serious obesity cases when previous weight loss methods have been unsuccessful. Before surgery, the bariatric professional assesses the patient's weight and medical history. The process includes proper diet and supplementation, along with regular check-ups.
