How to Identify Factitious Disorder (Munchausen Syndrome)

Identify common behaviors. Someone with factitious disorder may tamper with blood or urine samples, inflict wounds on oneself, or otherwise deceive medical teams with illness.^[6] Individuals may have an extended medical history with inconsistent details throughout.

• The most common physical complaints include belly pain, nausea/vomiting, difficulty breathing, and blacking out.^[7]

Discern whether the person actively tries to get ill.^[8] A person may try to purposefully infect a wound, go to crowded places in order to pick up a cold or virus, or increase risk of getting an infection. Other behaviors may include purposefully eating or drinking from containers that a sick person has used.

• The point of these behaviors is to get sick so the person can receive treatment and medical attention.

Note complaints of difficult to measure symptoms. The individual may complain of persistent problems that are difficult to measure, such as chronic diarrhea or stomach ache. Upon testing or medical examination, no symptoms are found to be present. ^[9]

• Other symptoms difficult to measure may include chest pains or difficulty breathing, and feeling faint or dizzy.

Note events when symptoms are present. The individual may report symptoms only when in the presence of other people. The symptoms may not appear when the person is alone or when nobody is around. The symptoms may also only appear when the person is being observed, either in a medical setting or by family or friends.^[10]

• Ask the person when the symptoms are present. Do the symptoms worsen when near family or friends? Does treatment appear to go well until a family member is present? Also, is the person hesitant to include family in treatment?

Examine eagerness to undergo exams and medical tests.^[11] Those with factitious disorder may appear overly eager to receive medical tests, procedures, or operations. They may request certain tests or insist on being tested for specific disorders or diseases.

• They may appear happy or gleeful when a medical doctor recommends testing or treatment. Note that people without factitious disorder may feel relief at finally getting help, but this is because they want to get better, not because they enjoy the role of being sick.

Observe comfort level in a medical setting. Someone with factitious disorder may have an extensive knowledge of medical treatment, disorders, medical terminology, and descriptions of illness.^[12] The person may appear at ease in a medical setting and even comfortable receiving medical care.

Observe seeking help from multiple sources.^[13] Someone may receive negative tests from one medical facility and choose to go to another facility or several others in order to get a positive response. Or, a person may go to several medical centers in order to have a diagnosis confirmed several times over. Generally, the pattern of behavior seeks to affirm the presence of an illness.

Detect hesitance for medical professionals to contact previous treatment teams. Factitious disorder often includes a long medical history, yet the person may hesitate for current treatment teams to contact previous treatment teams.^[14] The person may fear the truth being told or suspicions being raised. For this reason, they may deny past medical treatment, or refuse to share medical information.

• The person may hesitate for hospitals to call family or friends to confirm symptoms or medical history.

Monitor if problems worsen after treatment. If an individual receives treatment and then the symptoms worsen, it can be indicative of factitious disorder.^[15] The person may come back after treatment and say that symptoms have worsened for no apparent reason. There may be no apparent medical cause for the symptoms.

• Additional symptoms may spontaneously appear after treatment that appear unrelated to the symptoms being treated.

Note new problems after negative tests. If a person with factitious disorder receives medical tests and the results turn up negative, the individual may suddenly develop different or worsening of symptoms.^[16] The person may request more testing or more thorough testing, or may choose to receive tests from another medical center.

• The symptoms after a negative test may be unexplained or unrelated to what the individual was originally tested for.

Rule out depression. Symptoms of depression can include unexplained aches and pains or bodily discomfort. Other symptoms can include headaches, back pain, and stomach pain.^[17] While these symptoms often do not have a medical cause, they can be symptoms of depression.

• While symptoms may be medically unexplained, it’s important to look into the motivation of the pains or discomfort. These aches and pains may be manifestations of the feelings of depression, and the individual may show other symptoms of depression, such as low mood or energy, changes in appetite or sleep, and difficulty concentrating. If it appears to be attention-seeking behavior, it may be factitious disorder.

Parse out symptoms of obsessive compulsive disorder (OCD). Obsessive compulsive disorder can include unexplained medical symptoms, such as being convinced one is dying or suffering a heart attack or another severe disorder. A person may become obsessed with the idea that they are sick and needs treatment, and may demand medical tests and treatment. These obsessive thoughts may also have a compulsive component, like ritualistic cleansing or showering, repeatedly undergoing tests, or praying excessively.^[18]

• A person with OCD actively wants to get rid of the perceived medical disorder, which causes extreme stress. Like people with factitious disorder, they may be adamant that they are suffering from an illness or disease, and may be frustrated when medical professionals do not take the symptoms seriously. Unlike people diagnosed with factitious disorder, they want the symptoms to go away and do not perceive positive reinforcement from being medically treated.

Address anxiety. Some symptoms of anxiety can manifest physically, such as shallow breathing/shortness of breath, stomach upset, dizziness, muscle tension, headaches, sweating, tremors or twitches, and frequent urination. While these symptoms are a manifestation of anxiety, they can be confused with having a medical origin.^[19] People with anxiety may jump to negative conclusions and catastrophize situations. What may be a small medical problem (or no problem at all) may be perceived as a medical emergency. A perceived medical emergency may cause extreme tension, worry, and distress in the person. They may feel frustrated that medical practitioners are not taking the symptoms seriously and request further testing or go to another medical doctor.

• In people with anxiety, these symptoms cause distress and discomfort. They want the symptoms to go away and not persist, unlike those with factitious disorder.

Consider the possibility of hypochondria, also known as Illness Anxiety Disorder. Illness Anxiety Disorder is a fear-based disorder, in which a person seeks medical help for minor or imagined symptoms because they are afraid that they are extremely ill. The symptoms they worry about usually vary from day to day or week to week. It is characterized by extreme fear of illness, not enjoyment of illness, and a person with this disorder wants their symptoms to go away.
