A question that usually exists in people's minds is what bariatric surgery is and how it causes weight loss. Bariatric surgery has many different methods, but the working basis of these methods is almost the same and their focus is on consuming less food and, as a result, reducing the body's calorie intake. When the body receives less than the required amount of calories, you start losing weight.
By shrinking the stomach or changing the passage of food, bariatric surgeries reduce the amount of food intake. In simple words, people after bariatric surgery have less appetite and eat less because of the shrinking of the stomach.
The important thing is that there are people who are candidates for bariatric surgery who are almost sure that methods such as exercise and diet will not help them lose weight.
