Health anxiety, also known as hypochondria, is a condition where individuals excessively worry about having a serious illness. People with health anxiety often misinterpret normal bodily sensations as signs of disease, leading to constant fear and distress. This can result in frequent doctor visits and unnecessary medical tests, despite reassurance from healthcare professionals. The condition can significantly impact daily life, causing difficulties in work, relationships, and overall well-being. Treatment options include cognitive-behavioral therapy (CBT) and medication, which can help individuals manage their anxiety and reduce their preoccupation with health concerns.
