What exactly does an Internist (Internal Medicine Specialist) do?

An Internist is a medical doctor who specializes in diagnosing, treating, and preventing complex diseases primarily in adults. They are experts in managing conditions affecting multiple organ systems (Evaluation of Undifferentiated Symptoms, Polypharmacy & Medication Optimization), handling challenging diagnostic puzzles, and coordinating care for patients with multiple chronic illnesses. They often serve as consultants to other physicians.

Why is reviewing multiple medications (polypharmacy) important?

As people age or develop multiple health conditions, they often take many medications. Polypharmacy increases the risk of side effects, drug interactions, falls, confusion, and non-adherence. A careful review helps ensure each medication is truly necessary, effective, and safe, potentially leading to deprescribing (stopping unnecessary drugs) and simplifying the regimen.
