Do you qualify for weight loss surgery at Penn Medicine?

Bariatric surgery can be life-changing, but it may not be appropriate for everyone. Our bariatric medicine team ensures you meet the requirements for optimal results. Your success is our priority.

Candidates for bariatric surgery have to meet established criteria based on standards set by the National Institute of Health (NIH). Most insurance providers base their approvals on these criteria.

The standards include:

Body mass index (BMI)

A BMI greater than 40, or greater than 35 with medical complications related to obesity including:

Drug use, alcohol use, and psychiatric conditions

People with active alcohol use disorder, drug addictions, or major psychiatric disorders may not qualify for weight loss surgery. Some insurance providers require negative nicotine, alcohol, and drug tests to approve surgery.

Bariatric surgery may not be appropriate for people with certain health conditions, including:

  • Advanced lung disease
  • Cancer requiring active treatment
  • Heart failure

You also need to be healthy enough to have general anesthesia during surgery. Our team will help determine the best solution for you based on your current state of health.

Bariatric surgery screenings and pre-operative eligibility tests

If you meet the criteria for weight loss surgery, you’ll begin a series of evaluations and tests with our bariatric medicine team. These help us determine whether surgery is an appropriate treatment for you.
