What to expect at a Bariatric Surgery visit

Bariatric-surgery practices evaluate patients for surgical and, in many cases, medical weight-management paths. An initial consult often includes:

  • •An eligibility assessment (typically BMI-based) and a review of prior weight-loss efforts.
  • •A discussion of surgical options alongside non-surgical routes, which can include GLP-1 pharmacotherapy before or after surgery.
  • •A multidisciplinary work-up (nutrition, sometimes behavioral health) as part of surgical planning.
  • •A coverage and cost review, since surgical and medication benefits are handled differently by most plans.

This is general guidance for bariatric surgery practices, not a description of Sergey Lyass MD A Professional Corporation's specific protocol, services, or pricing. Confirm what a visit involves directly with the practice — 310-623-1786.
