In medical terminology, "osis" is a suffix that generally means a condition, disease, process, or increase. It is commonly used to denote a state, usually abnormal, involving a body part or function.
Here's a breakdown:
-
Condition or State: This is the most general meaning. It simply indicates that something is happening or present.
-
Disease: In some cases, "osis" directly implies a disease state.
-
Process: It can describe a process that's occurring, often pathological.
-
Increase: Sometimes, "osis" denotes an increase in something, such as the number of cells.
Examples of terms using the "osis" suffix:
- Dermatosis: Any disease of the skin.
- Neurosis: A mental disorder that causes a sense of distress.

- Psychosis: A mental disorder characterized by a disconnect from reality.

Important Considerations:
While "osis" often implies an abnormality, it's crucial to understand the specific term's meaning within its context. Some "osis" conditions are expected or normal, such as leukocytosis during an infection.
