Patient Eligibility

To be considered for bariatric surgery, you must meet the medical criteria for morbid obesity:

  • Weigh more than 100 lbs. over your ideal body weight, OR
  • Have a Body Mass Index (BMI) of over 40, OR
  • Have a BMI  over 35 AND are experiencing severe negative health effects such as high blood pressure or diabetes, related to being severely overweight

Patients may not weigh more than 450 pounds, which is the maximum UCSF X-ray equipment can accommodate. A nutritionist is available to help should you lose the excess weight to meet this requirement.

Other Requirements

  • Have an initial consultation with a surgeon. (Medical evaluations may be coordinated through the patient's primary care doctor.)
  • Have a psychological evaluation with a certified mental health professional.
  • Have documented participation in a supervised weight-loss program.

This information will be reviewed by our multidisciplinary team of surgeons, gastroenterologists and nurses. If you judged a candidate for the surgery, you will meet with a bariatric surgeon to discuss the procedure. After the preoperative evaluation and tests are completed, a follow-up appointment is set up so a surgery date may be scheduled. The entire process takes approximately six to eight months.
