Internal medicine is a medical specialty that focuses on the prevention, diagnosis, and treatment of a wide range of adult diseases and medical conditions. They are highly trained in the management of complex and chronic illnesses that affect various organ systems in the body.

Internal medicine doctors, or internists, provide comprehensive medical care for adults, often serving as primary care physicians. They are skilled in performing physical examinations, ordering and interpreting diagnostic tests, and developing treatment plans for conditions such as diabetes, hypertension, heart disease, respiratory disorders, gastrointestinal issues, and more. Internists are trained to address not only the physical health of their patients but also to consider their emotional and psychological well-being, making them well-rounded healthcare providers.
