Internal Medicine
Internal medicine physicians, or internists, specialize in the comprehensive diagnosis, treatment, and prevention of adult diseases. They manage a broad spectrum of conditions affecting internal organs including the heart, lungs, kidneys, gastrointestinal tract, and endocrine system.
Internists provide holistic care for chronic illnesses such as hypertension, diabetes, respiratory diseases, infectious diseases, and autoimmune disorders. They perform detailed clinical assessments, coordinate diagnostic investigations, and develop individualized medical treatment plans.
They often act as primary coordinators for complex cases, referring patients to subspecialists when needed, and emphasize preventive care and patient education to maintain long-term health and manage comorbidities effectively.
