As part of the bariatric surgery process, you are required to see a nutritionist and a psychologist prior to surgery. To maintain consistency, with rare exceptions, we require you to seek assistance from the following individuals only. As independent professionals with NO financial ties to University Bariatrics and extensive backgrounds in bariatric surgery, their unique inputs and perspectives provide an extremely valuable service to our program.
