Bariatric surgery reduces overall mortality by 25–50% in the long term and is the most effective treatment for morbid obesity.
If you have severe obesity (BMI >40, or >35 with health issues), bariatric surgery is the most effective medical intervention available. It doesn't just help you lose weight; it significantly reduces your risk of dying from obesity-related causes like heart disease and diabetes. Consult a specialist to see if you qualify.
