The doctor will ask about your symptoms and health history. A physical exam will be done. If the exam shows no disease, the doctor may order other tests. If no illness is found, the doctor may suspect illness anxiety disorder. Diagnosis is based on fear of illness that lasts:

• At least 6 months
• Despite negative tests
• And is not due to other mental health problems
