What to expect at an Internal Medicine visit

Internal-medicine practices manage adult and often complex chronic conditions. A GLP-1-related visit commonly involves:

  • •A review of chronic conditions, medications, and cardiovascular/metabolic risk.
  • •Baseline labs (A1c, metabolic panel, lipids) to guide treatment.
  • •A discussion of GLP-1 options for diabetes and/or weight management.
  • •A plan for follow-up monitoring and dose adjustment.

This is general guidance for internal medicine practices, not a description of Oana Klein's specific protocol, services, or pricing. Confirm what a visit involves directly with the practice — 415-448-1500.
