The department of Internal Medicine deals with the prevention, diagnosis and non-surgical treatment of various diseases. It serves as the first point of contact whenever a patient visits the hospital. A general physician conducts a physical examination of the patient and then recommends the necessary tests and diagnostic procedures. The results of these tests, the general physical examination and symptoms are then correlated to arrive at a final diagnosis. Depending on the final diagnosis, the patient is given the necessary treatment, usually medication by the general physician or is referred to a specialty department for further treatment.
