Internal medicine is a branch of medicine that deals with the prevention and treatment of diseases of internal organs, such as the heart, blood vessels, lungs, digestive organs, etc.
An internist is a doctor whose narrow specialty is internal medicine. Its biggest role is to help the patient regain his general health, and to prevent additional complications that could occur if the disease is not treated.
The essence of every diagnostic procedure is to discover the place, cause and size of the imbalance, and the therapeutic approach is to return the system to a balanced or, more precisely, to a harmonized state.
