Illness Anxiety Disorder (Hypochondria, Hypochondriasis)
What is illness anxiety disorder?
People with illness anxiety disorder -- also called hypochondria or hypochondriasis -- have an unrealistic fear that they have a serious medical condition or fear that they’re at high risk of becoming ill. They may misinterpret typical body functions as signs of illness.
Even after medical tests show no problems, people with hypochondriasis are still preoccupied with the idea that think they’re seriously sick. Their persistent health worries can interfere with their relationships, careers and life.
You may be more familiar with the term hypochondria or health anxiety. Healthcare providers now use the term illness anxiety disorder. People with illness anxiety disorder can’t control how they feel. Their fears are very real to them.
How common is illness anxiety disorder?
Illness anxiety disorder (hypochondria) is extremely rare. It affects about 0.1% of Americans. It typically appears during early adulthood. Illness anxiety disorder can affect all ages and genders.
What are the types of illness anxiety disorder?
Someone with illness anxiety disorder generally fits into one of these categories:
- Care-seeking: You spend a lot of time in a healthcare setting. You seek advice from multiple specialists and request medical tests.
- Care-avoidant: You avoid doctors and medical care. You might not trust doctors or you think they don’t take your symptoms seriously. This can create more fear and anxiety.
What is the difference between illness anxiety disorder and somatic symptom disorder?
Someone with somatic symptom disorder may obsess and worry about their health — just like someone with illness anxiety disorder. A person with somatic symptom disorder has true physical symptoms. But medical tests can’t pinpoint a cause for the physical symptom.
Symptoms and Causes
What causes illness anxiety disorder?
Healthcare experts don’t know why some people develop illness anxiety disorder. You may be more prone to illness anxiety disorder if you have a family history of:
- Childhood trauma, such as child abuse or neglect.
- Extreme stress.
- Health anxieties or other anxiety disorders in your family.
- Childhood illness or serious illness in your family during childhood.
- Mental health issues, such as anxiety or depression.
- Trauma, such as rape or physical or emotional abuse.
What are the symptoms of illness anxiety disorder?
People with illness anxiety disorder have ongoing but unrealistic fear about being seriously ill. The specific illness(es) that they worry about often changes.
Some people with illness anxiety disorder may actually have a diagnosed physical illness. But because of illness anxiety disorder, they may feel their condition is more severe than it is.
Symptoms of illness anxiety disorder include:
- Avoiding people or places due to worry about catching an illness.
- Constantly researching diseases and symptoms.
- Exaggerating symptoms and their severity (for instance, a cough becomes a sign of lung cancer).
- High level of anxiety about personal health.
- Obsession with normal body functions, such as heart rate.
- Oversharing your symptoms and health status with others.
- Repeatedly checking for signs of illness, such as taking your blood pressure or temperature.
- Seeking reassurance from loved ones about your symptoms or health.
- Uneasiness with healthy body functions like gas or sweating.
Diagnosis and Tests
How is illness anxiety disorder diagnosed?
To diagnose illness anxiety disorder, healthcare providers refer to the criteria listed in the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM), 5th edition. Your provider may make a diagnosis or they may refer you to a behavioral health specialist, such as a psychologist or psychiatrist.
A persistent fear about having a serious illness or developing one is the top symptom of illness anxiety disorder. Your provider may diagnose illness anxiety disorder if you have health anxiety (or other illness anxiety disorder symptoms) for six months or longer even after tests show that you’re not sick.
