Bariatric Surgery Center
Severe obesity is a complex condition with many causes, including genetics. Diet, exercise and medication often are not enough to enable people with severe obesity to lose weight and keep it off. If you struggle with this, weight-loss surgery (also known as bariatric surgery) may offer a road to a healthier, longer life.
The UCSF Bariatric Surgery Center is committed to delivering the highest quality care with compassion and respect. We offer a complete range of surgical weight-loss options, including gastric bypass and sleeve gastrectomy, and with more than 99 percent of our patients, we're able to use a minimally invasive (laparoscopic) approach. This reduces postoperative pain and complications, shortens hospital stays and allows patients to get back to normal activities sooner.
Our experienced team of bariatric surgeons, gastroenterologists, psychiatrists, nurses, physician assistants and dietitians is equipped to handle the most challenging and complicated cases, including repairs of unsuccessful bariatric operations done at other hospitals. We're also one of the few centers that perform bariatric surgery on obese patients with end-stage kidney or liver disease who have been denied an organ transplant because of their weight.
To keep the weight off, patients must commit to lifelong dietary, exercise and lifestyle changes after surgery. To help you succeed, we offer follow-up services, such as support groups, nutritional counseling and continuing education.
To find out whether you may be a candidate for bariatric surgery, please visit Eligibility for Weight Loss Surgery. We also hold monthly information sessions, which are free and open to the public. To be invited, send a request to [email protected].

- Most people lose 50 to 70 percent of their excess weight in the year following their surgery.
- Patients lose about 75 to 125 pounds on average.
- In 80 to 90 percent of patients, obesity-related problems, such as diabetes, sleep apnea, high blood pressure, arthritis and high cholesterol, improve or disappear.
- Long-term complications occur in only 1 to 3 percent of patients.
