Why is bariatric surgery done

Bariatric surgery is weight loss surgery. This surgery is done to reduce obesity. People who have a BMI of 35 to 40 can have bariatric surgery. The person's BMI should be between 19 and 25. If you are gaining weight and your BMI goes above 30, then you can reduce obesity with the help of a doctor. But they don't need surgery. However, if the BMI is between 35 and 40 and the person is healthy, the doctor may recommend bariatric surgery. In many cases, bariatric surgery is recommended for patients with a BMI less than 35 because such people are previously suffering from any disease like high BP, diabetes, any heart related disease etc
