Illness Anxiety Disorder is a mental health condition where a person is excessively worried about having a serious illness, even when there is little or no medical evidence to support this fear. Individuals with this disorder often misinterpret normal bodily sensations as signs of severe health issues, leading to constant anxiety and distress. They may frequently visit doctors or seek medical tests, hoping to find reassurance. This condition can significantly impact daily life, causing individuals to avoid certain activities or situations they believe could harm their health. Treatment often includes therapy, such as Cognitive Behavioral Therapy, which helps individuals manage their anxiety and develop healthier thought patterns.
