What does the suffix "-edema" indicate in medical terms?

The suffix "-edema" is derived from Greek, where it means "swelling." In medical terminology, it specifically refers to an abnormal accumulation of fluid in the interstitial spaces of tissues, which leads to swelling in certain areas of the body. Conditions such as peripheral edema, pulmonary edema, or lymphedema illustrate the application of this suffix, as they describe fluid buildup in different regions, resulting in observable swelling. Understanding this terminology helps health professionals accurately describe patient conditions and facilitate effective treatment plans. Thus, recognizing "-edema" as indicating swelling is essential in the medical field.
