Factitious disorder, previously called Munchausen syndrome, is a serious mental health condition in which people deceive others by pretending to be sick. They do this by faking symptoms, getting sick on purpose or hurting themselves. Factitious disorder also can happen when family members or caregivers falsely present others, such as children, as being ill, hurt or having a hard time functioning.
Factitious disorder symptoms can range from mild to severe. People may make up symptoms or even tamper with medical tests to convince others that they need treatment, such as high-risk surgery.
Factitious disorder isn't the same as making up medical issues for a benefit or reward, such as getting out of work or winning a lawsuit. Although people with factitious disorder know they are causing their symptoms or illnesses, they may not know why they do what they do or see themselves as having mental health issues.
Factitious disorder is a rare condition that can be hard to diagnose and treat. Help from medical and mental health professionals is critical to prevent serious injury and even death when people with factitious disorder hurt themselves.
Factitious disorder symptoms involve people trying to look ill, making themselves ill or hurting themselves. They also may fake symptoms, make symptoms seem worse than they are or pretend they can't do certain things because of their symptoms so they can deceive others. People with the condition work hard to hide their lies. It may be hard to know that their symptoms are part of a serious mental health condition. People with this condition continue with the lies, even without any benefit or reward, or when faced with evidence that doesn't support their claims.
Factitious disorder symptoms may include:
Factitious disorder imposed on another, previously called Munchausen syndrome by proxy, is when someone falsely claims that another person has physical or mental symptoms of illness or causes injury or disease in another person to deceive others.
People with this condition present another person as sick, hurt or having a hard time functioning, claiming they need medical help. Usually this involves a parent harming a child. This form of abuse can put a child in danger of being hurt or getting medical care that isn't needed.
Because people with factitious disorder become experts at faking symptoms and diseases or hurting themselves, it may be hard for healthcare professionals and loved ones to know whether symptoms and illnesses are real.
People with factitious disorder make up symptoms or cause illnesses in several ways. For example, they may:
People with factitious disorder may know the risk of injury or even death when they hurt themselves or seek treatment that's not needed. But they have a hard time managing their behaviors. They also aren't likely to seek help. Even when they see proof that they're causing their illness, such as a video, they often deny it and refuse mental health help.
If you think that a loved one may be exaggerating or faking health problems, it may help to try to talk to that person about your concerns. Try not to be angry or to judge or confront the person. Also try to reinforce and urge healthier, more productive activities rather than focus on beliefs and behaviors that aren't healthy. Offer support and care. If possible, help find treatment for the person.
If your loved one causes self-harm or attempts suicide, contact a suicide hotline. In the U.S., call or text 988 to reach the 988 Suicide & Crisis Lifeline, available 24 hours a day, seven days a week. Or use the Lifeline Chat. Services are free and confidential. The Suicide & Crisis Lifeline in the U.S. has a Spanish language phone line at 1-888-628-9454 (toll-free).
If you suspect that a child is being harmed or abused by a caregiver as part of factitious disorder, you can contact the Childhelp National Child Abuse Hotline at 1-800-422-4453 (toll-free). This hotline is available 24 hours a day, seven days a week. There also may be local and state child protective services agencies in your area.
The cause of factitious disorder isn't known. But a mix of mental health issues and stressful life experiences may cause the condition.
Several factors may raise the risk of developing factitious disorder, including:
Factitious disorder is thought to be rare, but it isn't known how many people have the condition. Some people use fake names. Some visit many hospitals and healthcare professionals. And some are never identified. This makes it hard to get a reliable estimate.
People with factitious disorder are willing to risk their lives to be seen as sick. They often have other mental health conditions as well. As a result, they face many possible complications, including:
Because the cause of factitious disorder isn't known, there's no way to prevent it. Recognizing and treating factitious disorder may help avoid potentially dangerous tests and treatments that aren't needed.
Diagnosing factitious disorder is often very hard. People with factitious disorder are experts at faking many diseases and conditions. And while these people often look like they have real and even life-threatening medical conditions, they may have brought those conditions on themselves.
The use of many healthcare professionals and hospitals, the use of fake names, and privacy and confidentiality laws may make it hard or even impossible to gather information about previous medical experiences.
Diagnosis is based on objectively identifying symptoms that are made up, rather than the person's intent or motivation for doing so. A healthcare professional may suspect that people have factitious disorder when:
To help figure out if a person has factitious disorder, healthcare professionals:
Treatment of factitious disorder is often hard, and there are no standard therapies. Because people with factitious disorder want to be in the sick role, they often aren't willing to seek or accept treatment for the condition. But if approached in a way that doesn't judge, people with factitious disorder may agree to have a mental health professional assess and treat them.
Directly accusing people of having factitious disorder usually makes them angry and defensive. This can cause them to suddenly end a relationship with a healthcare professional or hospital and seek treatment elsewhere. So healthcare professionals may try to create an "out" that spares people the humiliation of admitting to faking symptoms and instead offer information and help.
For example, healthcare professionals may reassure people that not having an explanation for medical symptoms is stressful and suggest that the stress may be responsible for some physical complaints. Or the healthcare professional may ask people with factitious order to agree that if the next medical treatment doesn't work, they'll explore together the idea of a possible mental health reason for the illness. The healthcare professional also may suggest that the focus of treatment be on making them better able to function and making their quality of life better rather than treating symptoms.
Either way, the healthcare professionals try to steer people with factitious disorder toward care with a mental health professional. And both healthcare professionals and loved ones can reinforce healthy, productive behaviors and not give too much attention to symptoms.
Treatment often focuses on managing the condition and making people better able to function, rather than trying to cure it. Treatment generally includes:
Treatment may not be accepted or may not help, especially for people with severe factitious disorder. In these cases, the goal may be to stop further invasive or risky treatments. When factitious disorder is imposed on others, healthcare professionals assess for abuse and need to report the abuse to authorities.
Along with professional treatment, these tips may help people who have factitious disorder:
People with factitious disorder are likely to first get care for this condition when healthcare professionals raise concerns that mental health issues may play a part in an illness. If people have symptoms of factitious disorder, healthcare professionals may get permission to contact family members in advance to talk about their loved one's health history.
Here's some information to help you get ready for that talk.
To get prepared, make a list of:
For factitious disorder, some questions to ask the healthcare professional include:
The doctor or other healthcare professional will likely ask you several questions, including:
