Illness anxiety disorder (IAD) is a preoccupation that physical symptoms are signs of a serious illness, even when there is no medical evidence to support the presence of an illness.
Causes
People with IAD are overly focused on, and always thinking about, their physical health. They have an unrealistic fear of having or developing a serious disease. This disorder occurs equally in men and women.
The way people with IAD think about their physical symptoms can make them more likely to have this condition. As they focus on and worry about physical sensations, a cycle of symptoms and worry begins, which can be hard to stop.
It is important to realize that people with IAD do not purposely create these symptoms. They aren't able to control the symptoms.
People who have a history of physical or sexual abuse are more likely to have IAD. But this doesn't mean that everyone with IAD has a history of abuse.
Exams and Tests
The provider will perform a physical exam. Tests may be ordered to look for illness. A mental health evaluation may be done to look for other related disorders.
Treatment
It is important to have a supportive relationship with a provider. There should be only one primary care provider. This helps avoid having too many tests and procedures.
Finding a mental health provider who has experience treating this disorder with talk therapy can be helpful. Cognitive behavioral therapy (CBT), a kind of talk therapy, can help you deal with your symptoms. During therapy, you will learn:
- To recognize what seems to make the symptoms worse
- To develop methods of coping with the symptoms
- To keep yourself more active, even if you still have symptoms
Antidepressants can help reduce the worry and physical symptoms of this disorder if talk therapy has not been effective or only partially effective.
Outlook (Prognosis)
The disorder is usually long-term (chronic), unless psychological factors or mood and anxiety disorders are treated.
Possible Complications
Complications of IAD may include:
- Complications from invasive medical testing to look for the cause of symptoms
- Dependence on pain relievers or sedatives
- Depression, anxiety, or panic disorder
- Lost time from work due to frequent appointments with providers
When to Contact a Medical Professional
Contact your provider if you or your child has symptoms of IAD.
