What term refers to a condition that occurs as a result of another medical condition?

The term that best describes a condition that occurs as a result of another medical condition is "complication." A complication refers to an additional problem that develops during the course of a disease or condition, which can complicate diagnosis, treatment, or the overall prognosis.

For instance, if a patient has diabetes, they may develop complications such as neuropathy, which is a condition that stems from the primary disease. This demonstrates how complications arise not independently, but as outcomes influenced by the original medical issue.

While "manifestation" typically refers to the observable signs or symptoms of a disease, it does not necessarily indicate a secondary condition arising from the primary one. "Consequence" is a broader term that could refer to any outcome, not specifically a medical condition linked to another. "Syndrome" is a collection of signs and symptoms that occur together and characterize a particular abnormality or condition, but it does not specifically denote a condition caused by another pre-existing condition. Thus, "complication" is the most precise term in this context.
