Here are answers to some common questions about receiving Internal Medicine care with Dr. Mieras:

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 receive 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. Mieras 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. Mieras serves as the central coordinator for your care, managing referrals to specialists like your cardiologist or surgeon. We review all reports and ensure that all treatments and medications work together safely and effectively. We'll also make sure everything is properly documented and communicated.
I have a set of confusing symptoms that other doctors haven't been able to diagnose. Can an Internist help?
Yes, an internist can be very helpful. Internists are highly trained in diagnosing complex medical conditions, often considered "medical detectives." Dr. Mieras is skilled at evaluating vague or unusual symptoms to arrive at an accurate diagnosis.
Can you help me manage my medications?
Yes. Medication management is a critical part of internal medicine, especially for patients with multiple conditions. Dr. Mieras will review all of your prescriptions (even those from specialists) to check for interactions, ensure proper dosing, and simplify your regimen whenever possible.
Do you only treat sick patients, or do you also focus on preventive care?
Dr. Mieras' practice emphasizes preventive care as a major focus. A significant portion of our work involves adult wellness and disease prevention, including annual physicals, managing risk factors, and providing recommended screenings.
What kind of adult immunizations do you provide?
Dr. Mieras provides common adult vaccines, including the annual flu shot, tetanus boosters (Tdap), shingles (Shingrix), and pneumonia (Prevnar/Pneumovax) vaccines. She will review your immunization history and recommend vaccinations based on your age, health status, and CDC guidelines.
Should I see an Internist for a common illness like a sinus infection?
Yes, Dr. Mieras is fully equipped to diagnose and treat common illnesses like sinus infections. As your primary care provider, she can address a wide range of adult health concerns, including acute infections.
