Mayo Clinic's approach


A team of medical experts, including endocrinologists, surgeons, dietitians and psychologists, helps identify candidates who could most benefit from gastric bypass and works intensively with you before and after your procedure to help achieve a long-lasting result. In some cases, follow-up care can be conducted by your hometown doctor, working closely with the Mayo team.

Bariatric expertise

The Mayo Clinic team has a combined experience of more than 75 years of caring for people undergoing bariatric surgery.

Minimally invasive approach

Mayo Clinic uses minimally invasive techniques for gastric bypass whenever possible. This approach offers smaller incisions, less pain, shorter hospital stays and faster recovery than traditional open surgery.

Comprehensive, holistic care

In addition to your gastric bypass, you may receive treatment from other Mayo Clinic specialists, including nutrition therapy, behavior modification and pharmacotherapy. For out-of-state patients, Mayo Clinic offers efficient, condensed scheduling. Mayo Clinic will work with providers in your area to meet your needs.
