How can you determine that bariatric surgery is medically necessary?

Would have you tried: If your BMI is in the obese or morbidly obese range, and you have tried multiple lifestyle modifications including diet and exercise then bariatric surgery would be the next option. This should be considered, if you have comorbid conditions including diabetes, hypertension, and/or coronary artery disease. Surgery should always be a last option.

By your BMI: Bariatric surgery is considered medically necessary when your BMI is greater than 40 (about 100 lbs overweight) or your BMI is greater than 35 (about 60lbs overweight) with 2 comorbidities (other medical problems). These are the indications for bariatric surgery as per the american society of metabolic and bariatric surgeons.

Very complex but ...: in general the NIH guidelines are anyone with a BMI >35 with other related medical problems to obesity, or anyone with a BMI > 40 regardless. Insurance companies may have different qualifications as well. It's a decision you should make with your surgeon, primary care doctor, and family. Many of my patients say the surgery saved their life, and it can be a powerful way to regain your health.
