General Medicine, also known as Internal Medicine, is a medical specialty focused on the diagnosis, treatment, and prevention of diseases in adults. It encompasses a broad range of conditions affecting the internal organs, such as the heart, lungs, liver, kidneys, and gastrointestinal system, as well as systemic illnesses like diabetes, hypertension, and autoimmune disorders.

The field emphasizes clinical reasoning, patient-centered care, and preventive medicine. General Medicine practitioners must possess a deep understanding of pathophysiology and diagnostic methods, and they are often at the forefront of managing undifferentiated symptoms such as fatigue, fever, or weight loss.
