Chief Complaint

"I've had diarrhea now for 3 years and I keep losing weight.” Patient also complains of a racing heart, headache and dizziness.

History of Present Illness

Diarrhea began a few days after the patient had reconstructive jaw surgery. The patient states that extensive evaluation at two institutions failed to reveal a cause of her illness. She states, "My stool weighed 1008 grams each day (normal weight for women is 87 +/- 8 g/day). The diarrhea was secretory in nature without steatorrhea. They did biopsies, x-rays, upper and lower endoscopy and they found nothing...no melanosis coli, ruled out microscopic colitis, small bowel disease...and my serum gastrin and VIP were within normal limits. I also had no pathogens in my stool culture.”  About two years after onset of diarrhea, she went to another medical center where diagnostic tests were repeated with no diagnosis. After a colonoscopy she had severe bleeding and required multiple units of blood and her weight dropped to 108 pounds. At that time total parenteral nutrition was begun until she healed.

General Appearance

Patient appears thin and pale. She has a thick notebook full of notes which she refers to when discussing her medical history. She has to be interrupted repeatedly to get pertinent information, and she smiles and giggles occasionally while talking about her illness.

Past Medical History

No significant medical or psychiatric history other than fractured right jaw after MVA three years ago.

Family History

Patient has been married for four years. Mother is 65 with hypertension and obesity. Father is 72 with CAD and hypercholesterolemia. Patient has no siblings. She states, "My father abused me and my mother and I don't talk to him. He used to hit us. My homelife was terrible.”

Social History

The patient lives with her husband. She smokes, stating, "only 1 or 2 a day" and drinks wine once or twice a week. Denies recreational drug use. She is enrolled in an online graduate school program and studying biology. "My husband works all day, so I'm alone a lot. I'd really like to go to medical school, but I'm just not sure I could do it because of my health.”

I am wondering if she has been evaluated for an underlying health condition like a connective tissue disorder, especially with the bleeding that started after the colonoscopy and how everything started after a jaw surgery. Just a thought....

UPDATE!

Most of you figured it out...

The positive bisacodyl test suggests the patient has been taking bisacodyl – a common over-the-counter medication used to treat constipation. In the presence of her husband, the patient was asked if she was taking a laxative. With a few tears she said, “Absolutely not, I don’t even know what bisacodyl is.” The husband subsequently searched the house and did not find any; however, a few months later he called saying, “I searched her closet and found an empty box of Dulcolax”

After discovering the Dulcolax, the husband and the patient agreed to seek psychological counseling. The patient’s parents were contacted to attempt to determine the patient’s motivation for taking the laxative secretly. The father would not give any information. The mother stated there was no history of an eating disorder or abuse. She said, “My daughter has always been a great believer in medicine, and she doesn't see the risks. For example, she's had multiple orthopedic surgeries without any clear need, and the jaw surgery was done for...well I don’t know why. She's married to a loving and caring husband but can’t have babies. The diarrhea started about 3 months after she was told she couldn’t have children.”

After several weeks of therapy, the psychologist arrived at a diagnosis of Munchausen Syndrome.

What is Munchausen Syndrome?

This syndrome is known in the medical community as factitious disorder imposed on self (FDIS). It was first reported in 1951 by Richard Alan John Asher in a description of Baron von Munchhausen (1720-1797), though it is said that Claudius Galen, a second-century Roman physician was the first to call attention to it.  FDIS occurs when a person falsifies, induces, and/or exaggerates an illness to gain attention and sympathy. The person lies about symptoms, may sabotage medical tests (by adding blood to urine, for example), or harms themselves to display symptoms. Though the self-induction of disease is a conscious act, the underlying motivation is typically unconscious. It is estimated that between 3-5% of physician-patient encounters involve fictitious disease. It is very difficult to identify and treat FDIS due to the dishonesty of the patient. This syndrome has been seen in the media a great deal in the form of Munchausen by proxy, in which a caregiver perpetrates the above symptoms to a person under their care. This can be a child, elderly adult or person with a disability.

The exact cause is unknown, but there is a correlation between the development of FDIS and a history of child abuse or neglect. Those with a history of frequent illnesses that require hospitalization may also be more likely to develop FDIS. Other triggers may include the death of a loved one at a young age, being abandoned and personality disorder.

Warning signs include:

  • A dramatic and inconsistent medical history
  • Unclear symptoms that are uncontrollable and become more severe or change once treatment has begun
  • Problems with identity and self-esteem
  • Predictable relapses following improvement
  • Extensive medical knowledge, terminology, and hospital processes as well as textbook descriptions of illnesses.
  • Presence of multiple surgical scars
  • Appearance of new or additional symptoms following negative test results
  • Presence of symptoms only when patient is alone/unobserved
  • Eagerness to have medical tests, procedures or operations. Displays extreme comfort in hospital setting
  • History of seeing treatment at numerous hospitals, clinics and doctor’s offices, often in different cities
  • Reluctance to allow healthcare professionals to meet with or talk to family, friends or prior HCPs

Individuals with FDIS have been known to put blood in urine, inject themselves with feces, rub dirt in IV lines, put rubber bands around arms or legs, pretend to take medications, and deliberate dehydration to name a few. Mechanisms include self-induced infections, surreptitious ingestion of medicines, vitamins or minerals, phlebotomy of self or animal, thermometer manipulation and simulation of clinical manifestations, sometimes using falsified medical records.

Due to the dishonesty of the patient, FDIS is difficult to diagnose. If the HCP finds medically unexplainable symptoms, they may refer the patient for mental health services, but the patient often will not follow up. The DSMMD 5th edition is the gold standard for diagnosis.

Treatment involves helping the patient recognize the consequences of self-harm through education and therapy. Having the person work only with one physician is suggested. The goal is behavior modification. Cognitive-behavioral therapy has been shown to be useful as well as family and/or group therapy. No medications have been shown to be effective.

I highly recommend reading the article upon which this case study was based – there are six case studies – all of them fascinating (see the references).

Allnurses had a case of Munchausen by Internet a few years ago. To read more about this new twist on FDIS read: Munchausen by Internet: The Lying Disease that Preys on the Heart

This is an incredibly difficult problem. The estimate of 3-5% might be a little high, but I do feel that I’ve encountered one or two in my career. And more— I think I’ve seen some on facebook. And it is SO HARD when the narrative they present is “My chronic illness is a medical mystery” “Doctors don’t believe me and therefore I have medical trauma from being undiagnosed” “I am a member of the chronic-illness-or-disability community and I am so grateful for their support.”  Because there ARE many people with difficult or invisible chronic conditions, and there ARE many people who are truly ill but their providers don’t believe them. It just seems like it’s almost impossible to sort out who is truly suffering from a mysterious illness vs who may be engaging in Munchausen behavior.
