One of my interests is the origin and evolution (etymology) of medical terminology. Because of this, in October 2012 we started on the Clinical Anatomy Associates website a blog called "Medical Terminology Daily". Originally, I thought we could do one article per day… oh how wrong I was!!, but we kept the name and, since then, over one thousand articles have been published.
The first article in the blog was the medical term “Bariatric”. Today we will analyze this term again and the medical derivations that arise from one of these root terms.
The term "bariatric" is a compound word with two Greek roots: βάρος, meaning "weight" or "pressure", and γιατρός meaning "doctor, physician, or healer". The adjectival suffix [-ic] that closes the word means "pertaining to". The term bariatric then means "pertaining to weight-related medicine".
Let’s look at some of the many uses of the root “iatr-“in medical terminology. Remember, you only add an “o” as in “iatr-o” (the combining form of a word) when you are combining a root term with another root or a suffix.
