Internal Medicine: 6 Sub-Specialties Everyone Should Know

Dedication Health

Internal medicine is a term that’s often thrown around, but few know what it really means, what the field covers, and who’s involved in it. However, understanding the basics of it can totally change your life if you’re impacted by certain conditions. On this page, we’ll break down what internal medicine is and explore a few of its sub-specialties.

What is Internal Medicine?

To put it simply, internal medicine refers to the study, prevention, diagnosis, and treatment of diseases which impact adults on the inside. To become an internal medicine specialist, also called an internist, a physician must undergo a minimum of 1-3 years of additional schooling. Some internists become general internists or generalists. This means they look at all they body’s internal systems. Others focus on one particular area of the body. We’ll break down a few of these sub-specialties in just a moment.

Suffice it to say, internists are the experts. They’re the ones doctors call when they’re stumped, a patient isn’t responding to treatment, or someone has a case that’s too advanced for them to handle. So, if you’re really sick or are having trouble getting a diagnosis, you’ll want to seek out the help of an internal medicine specialist too.

There are numerous sub-specialties and various medical organizations and authorities will break down the subspecialties a bit differently. That said, the six listed below are fairly universal.
