What does the suffix "-emia" refer to?

The suffix "-emia" is derived from the Greek word "haima," which means blood. It specifically refers to a condition related to the blood, often indicating the presence of a particular substance in the blood or a state concerning the blood. For example, "anemia" refers to a condition characterized by a deficiency of red blood cells or hemoglobin in the blood. Because of its connection to blood-related conditions, this suffix is commonly used in medical terminology to describe various disorders that involve the blood.
