During surgery, childbirth, etc. at a hospital, doctors update the patient's family with information about the patient's health. In this kind of situation, the doctors refer to the patient's health as their "condition".
There are a few specialized terms that doctors use to describe a patient's condition:
- A patient in "critical condition" is in danger of dying.
- A patient in "stable condition" is no longer in as much danger.
- A patient in "good" condition is OK and just needs to rest.
If someone is in the hospital and you don't know if they're OK, you can ask:
What's his condition?
Another place where a person's "condition" is discussed is on the news.
