Internal Medicine, also known as Internal Diseases, is a medical specialty focused on the diagnosis and treatment of diseases and disorders affecting the internal organs and systems of the body such as the cardiovascular system, respiratory system, digestive system, endocrine system, and immune system.
Doctors of internal medicine, also known as internists, are trained to provide care for adult patients and may specialize in a specific field of internal medicine such as cardiology (heart diseases), pulmonology (lung diseases), or gastroenterology (digestive diseases). They are often the primary healthcare providers for patients with chronic conditions such as diabetes, hypertension, and heart disease and are specialized in managing and coordinating the care of these patients.
