Internal Medicine encompasses a broad spectrum of diseases, and internists are often referred to as “doctors for adults” because they are equipped to handle complex medical cases, often serving as primary care physicians for adult patients. They have a deep understanding of how different organ systems in the body interact and influence each other.

Internists commonly deal with chronic diseases such as diabetes, hypertension, heart disease, lung diseases, gastrointestinal disorders, kidney diseases, and more. They are skilled in performing comprehensive physical examinations, interpreting diagnostic tests, and developing treatment plans that may include medication, lifestyle modifications, and referrals to other specialists when necessary.
