Hypochondria is a health anxiety disorder. It is often chronic. A person with hypochondria is often very anxious about their health. A hypochondriac fears that a real or imagined minor physical symptom is a sign of serious illness. Even when several doctors assure them otherwise, a hypochondriac is convinced that they have a serious disease. Psychiatric counseling and medications can relieve some, if not all, of the anxiety and suffering. Left untreated, hypochondria can be debilitating and affect daily function.

It is often difficult to identify a specific cause for hypochondria.
