About This Clinician

Brian First is an Internal Medicine physician in San Diego whose NPPES record also lists an obesity-medicine or bariatric-medicine taxonomy as a secondary specialty. Primary-care and family-medicine clinicians who carry this secondary designation are among those most likely to actively manage GLP-1 prescribing, though this registry entry does not confirm current prescribing practices — call ahead to confirm.

Locally, this is 1 of 1407 Internal Medicine practices in San Diego carrying this exact taxonomy in our directory.

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 Brian First's specific protocol, services, or pricing. Confirm what a visit involves directly with the practice — 858-292-0108.
