A weight loss surgery is recommended only if medical management of excess
weight is
not possible or the patient is
not responding to it. Also, just
weight is
not a parameter—person’s height, waist, body surface area, BMI etc are all considered.
First the doctor will assess him, take detailed medical history, rule out causes of weight gain with appropriate tests (diabetes, hypothyroidism, adrenal gland problem, anemia, liver and kidney problems), assess his diet, physical activity level etc.
