Internal medicine is a specialization in the medical field which deals with non-surgical conditions in adults. More specifically, it deals with the prevention, diagnosis, and treatment of a wide variety of adult conditions. Internist is the term used to refer to doctors who specialize in internal medicine. Internists are trained specifically to deal with diseases that affect multiple body systems. It should be noted that while a lot of people use internists as their primary physician, internists are not the same as general practitioners, family physicians, or family practitioners.
One common misconception is that internal medicine is meant to treat conditions involving the internal organs. However, the fact is that this specialization also deals with external conditions. Indeed, internal medicine does not focus on one part or system of the body. Instead, it takes into consideration the entire human body. As such, internists are highly sought after, especially if the condition cannot be limited to a single system.
Perhaps the most critical aspect of an internist’s job is to diagnose the patient’s illness. An internist has a wide variety of tools at his disposal in order to make an accurate diagnosis. These tools include laboratory tests and patient interviews.
Under internal medicine, we will find many subspecialties. These include cardiology, endocrinology, gastroenterology, hematology, infectious diseases, oncology, nephrology, pulmonology, and geriatic medicine, among others.
In order to become an internist, one has to undergo basic medical school first. Once the basic courses have been finished, the doctor has to undergo specialty training for internal medicine. The specifics regarding the period of study and courses required will differ from one country to another.
