In layman terms, what is bariatric and metabolic surgery and how does it help reduce chances of obesity-related death?

Bariatric surgery helps patients achieve weight loss by reducing the size of the stomach. Talking about those who are morbidly obese, with a Body Mass Index (BMI) of between 35 to 40, by losing weight they can achieve better blood-sugar levels, and this helps decrease the chances of death due to┬ádiabetes or other weight-related medical conditions like hypertension, fatty liver disease, and others. Patients with sleep apnea breathe better after surgery. And, of course, weight loss means it’s easier on their knees and joints. In patients who need bariatric surgery, only about 30% are diabetic, but almost all are obese.
