Here are answers to some common questions about receiving Internal Medicine care with Dr. Horton:
- What is the difference between an Internal Medicine doctor and a Family Medicine doctor?
- Internal Medicine physicians, or Internists, specialize in adult healthcare (typically age 18 and older). They have extensive training in diagnosing and managing complex adult illnesses and chronic conditions. Family Medicine physicians, in contrast, provide care for patients of all ages, including children.
- I have multiple chronic conditions, like heart disease and diabetes. Is an Internist a good choice for me?
- Yes. Managing multiple chronic conditions is a core strength of Internal Medicine. Dr. Horton is an expert in understanding how different adult diseases interact and can coordinate all aspects of care, including medications and specialist visits, to create a cohesive health plan.
- How do you coordinate care with my other doctors, like my cardiologist or surgeon?
- Dr. Horton serves as the central point for your health information, coordinating care with your cardiologist and surgeon. We manage referrals, review specialist reports, and ensure all treatments and medications work together safely and effectively.
- Can you help me manage my medications?
- Yes, medication management is a critical part of internal medicine, especially for patients with multiple conditions. Dr. Horton will review all of your prescriptions (even those from specialists) to check for interactions, ensure proper dosing, and simplify your regimen whenever possible.

- I have a set of confusing symptoms that other doctors haven't been able to diagnose. Can an Internist help?
- Yes, an internist like Dr. Horton can be very helpful.
