Greasy
Greasy
Greasy (/ˈɡriːzi/ or /ˈɡriːsɪ/) is an adjective used in medical terminology to describe a surface that is slippery or shiny, often due to the presence of an oily or fatty substance.
Etymology
The term "greasy" originates from the Old English word "gresig," which means "fatty" or "oily." It has been used in the English language since the 14th century.
Medical Usage
In medical context, "greasy" is often used to describe the appearance or texture of certain skin conditions. For example, skin affected by seborrheic dermatitis may appear greasy due to excessive production of sebum, an oily substance produced by the skin's sebaceous glands. Similarly, a greasy appearance can be a characteristic of other skin conditions such as rosacea and acne.
The term can also be used to describe the consistency of certain bodily fluids or discharges. For example, a greasy stool could indicate a malabsorption disorder such as celiac disease or pancreatic insufficiency.
