Obesity surgery, also known as bariatric surgery, is a medical intervention that aims to promote weight loss by altering the digestive system’s anatomy and physiology. It is typically considered for individuals with severe obesity (usually with a body mass index, or BMI, of 40 or higher) or those with a BMI of 35 or higher who have significant obesity-related health conditions.
There are different types of bariatric surgeries, each with its own mechanisms and effects on weight loss and metabolic changes.
