What an endocrinologist does

Endocrinologists specialize in hormone-related conditions — diabetes, thyroid disease, and metabolic disorders. They were prescribing GLP-1 medications for type 2 diabetes years before the drugs became known for weight loss, so they tend to have deep experience with dosing, side effects, and how these medications interact with other conditions.

Asking about GLP‑1 treatment at Jessica Castellanos-Diaz

Call (407) 932-6190 and ask these questions before booking:

  • ✓Do you currently prescribe GLP‑1 medications (semaglutide or tirzepatide) for weight loss?
  • ✓Do you work with my insurance, or is the program cash-pay — and what does a month cost all-in?
  • ✓Is the medication a brand-name product, or compounded by a compounding pharmacy?
  • ✓What follow-up is included for dose changes and side effects?

About compounded medications: A compounded drug is prepared by a state-licensed compounding pharmacy. Compounded drugs are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, and they are not the same as FDA-approved generic drugs. Ask any practice which it dispenses and which pharmacy prepares it.
