A hypochondriac, or hypochondriasis, is a person who is excessively worried about having a serious illness, often interpreting normal bodily sensations as signs of disease. This condition can lead to significant anxiety and distress, prompting individuals to frequently seek medical reassurance or undergo unnecessary tests. While the fears may be unfounded, the emotional impact is very real for those affected. Treatment often involves therapy and, in some cases, medication to help manage anxiety.
