Definition

Somatization disorder is a psychiatric condition marked by multiple medically unexplained physical, or somatic, symptoms. In order to qualify for the diagnosis of somatization disorder, somatic complaints must be serious enough to interfere significantly with a person's ability to perform important activities, such as work, school or family and social responsibilities, or lead the person experiencing the symptoms to seek medical treatment.

Somatization disorder has long been recognized by psychiatrists and psychologists, and was originally called Briquet's syndrome in honor of Paul Briquet, a French physician who first described the disorder in the nineteenth century. It is included in the category of somatoform disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), the professional handbook that aids clinicians in diagnosing patients' mental disorders. The term "somatoform" means that the physical symptoms have a psychological origin.

Description

Individuals with somatization disorder suffer from a number of vague physical symptoms, involving at least four different physical functions or parts of the body. The physical symptoms that characterize somatization disorder cannot be attributed to medical conditions or to the use of drugs, and individuals with somatization disorder often undergo numerous medical tests (with negative results) before the psychological cause of their distress is identified. They often use impressionistic and colorful language to describe their symptoms, describing burning sensations, pains that move from place to place, strange tastes on the tongue, tingling, or tremors. While many symptoms resemble those associated with genuine diseases, some of the symptoms reported by people with somatization disorder are not. The individual usually visits many different physicians, but the information they provide about the patient's symptoms can be inconsistent. It is important to note that while the physical symptoms of somatization disorder frequently lack medical explanations, they are not intentionally fabricated. The typical person with somatization disorder has suffered from physical pain, discomfort, and dysfunction for an extended period of time and consulted several doctors; they are hopeful that they one can be found who can identify the cause of their illness and provide relief.

Somatization disorder can be dangerous, since patients may end up taking several different medications, thereby risking harmful drug interactions.

Causes and symptoms

Causes

DEFENSE AGAINST PSYCHOLOGICAL DISTRESS. One of the oldest theories about the cause of somatization disorder suggests that it is a way of avoiding psychological distress. Rather than experiencing depression or anxiety, some individuals will develop physical symptoms. According to this model, somatization disorder is a defense against psychological pain that allows some people to avoid the stigma of a psychiatric diagnosis. While getting the care and nurturing they need from doctors and others who are responsive to their apparent medical illnesses, many patients are encouraged to continue their manipulative behavior.

Many patients described by Sigmund Freud would be diagnosed today with somatization disorder. His patients were usually young women who complained of numerous physical symptoms. In the process of speaking with Freud, they would often recall a number of distressing memories; discussing these memories frequently led to the relief of physical symptoms. These cases formed the foundation of Freud's psychoanalytic treatment. Although this theory offers a plausible explanation for somatization disorder, research indicates that people with multiple physical symptoms are actually more likely to report psychiatric symptoms than those with few physical problems. These findings appear to support a connection between psychological and physical distress, but are inconsistent with the idea that physical symptoms offer a defense against overt psychiatric symptoms.

HEIGHTENED SENSITIVITY TO PHYSICAL SENSATIONS. An alternative theory suggests that somatization disorder arises from a heightened sensitivity to internal sensations. People with somatization disorder may be keenly aware of the minor pains and discomforts that most people simply ignore. A similar theory has been offered to account for panic disorder . Studies have shown that people with panic disorder are particularly sensitive to internal sensations like breathing rate and heartbeats, which may lead them to react with intense fear to minor internal changes. The physiological or psychological origins of this hypersensitivity to internal sensations and their relevance to somatization disorder are still not well understood.

CATASTROPHIC THINKING ABOUT PHYSICAL SENSATIONS. According to these thoughts, somatization disorder results from negative beliefs and exaggerated fears about the significance of physical sensations. Individuals with somatization disorder are thus more likely to believe that vague physical symptoms are indicators of serious disease and to seek treatment for them. For instance, someone with somatization disorder may fear that a headache signals a brain tumor, or that shortness of breath indicates the onset of asthma. When their doctors can find no medical explanation for the symptoms, the patients may fear that they have a rare disease; they frantically look for specialists who can provide a diagnosis. Anxiety causes them to focus even more intensely on their symptoms, which in turn become more disabling. Many people with somatization disorder reduce or eliminate many activities out of fear that exertion will worsen their symptoms. With fewer activities to distract them from their symptoms, they spend more time worrying about physical problems, resulting in greater distress and disability.

Symptoms

Gastrointestinal (GI) complaints, such as nausea, bloating, diarrhea, and sensitivities to certain foods are common, and at least two different GI symptoms are required for the diagnosis. Sexual or reproductive symptoms, including pain during intercourse, menstrual problems, and erectile dysfunction are also necessary features for a diagnosis for somatization disorder. Other frequent symptoms are headaches, pain in the back or joints, difficulty swallowing or speaking, and urinary retention. To qualify for the diagnosis, at least one symptom must resemble a neurological disorder, such as seizures , problems with coordination or balance, or paralysis.

Demographics

According to the DSM-IV-TR , somatization disorder is rare in males in the United States, although higher rates are seen among males from some cultural and ethnic groups. The DSM-IV-TR estimates that between 0.2% and 2% of women, and less than 0.2% of men, suffer from somatization disorder in the U.S. Sex ratios may arise from different rates of seeking treatment. However, studies of unexplained somatic symptoms in the general population find less striking differences in rates between men and women. Specific symptoms may vary across cultures. For example, the DSM-IV-TR notes that the sensation of worms in the head or ants crawling under the skin are sometimes reported in African and South Asian countries, but rarely seen in North American patients.

Diagnosis

To receive a diagnosis of somatization disorder, the individual must have a history of multiple physical complaints that began before age 30 and that continued for several years ( DSM-IV-TR ). These symptoms must cause significant impairment to social, occupational or other areas of functioning—or lead the patient to seek medical treatment.

Each of the following four criteria must be met.

  • The individual must report a history of pain affecting at least four different parts or functions of the body. Examples include headaches, back, joint, chest or abdominal pain, or pain during menstruation or sexual intercourse.
  • A history of at least two gastrointestinal symptoms, such as nausea, bloating, vomiting, diarrhea, or food intolerance must be reported.
  • There must be a history of at least one sexual or reproductive symptom, such as lack of interest in sex, problems achieving erection or ejaculation, irregular menstrual periods, excessive menstrual bleeding, or vomiting throughout pregnancy.
  • One symptom must mimic a neurological condition. Examples include weakness, paralysis, problems with balance or coordination, seizures, hallucinations , loss of sensations such as touch, seeing, hearing, tasting, smelling—or difficulty swallowing or speaking, or amnesia and loss of consciousness. Pseudo-neurologic symptoms like these are the primary characteristics of another somatoform disorder known as "conversion disorder."

If a thorough medical evaluation reveals no evidence of an underlying medical- or drug- or medication-induced condition, the diagnosis of somatization disorder is likely. People with genuine medical conditions can qualify for the diagnosis if the level of functional impairment reported is more than would be expected based on medical findings. The symptoms must not be intentionally produced. If the patient is feigning symptoms, a diagnosis of factitious disorder or malingering would most likely be considered.

Treatments

Cognitive behavior therapy

Cognitive-behavioral therapy (CBT) for somatization disorder focuses on changing negative patterns of thoughts, feelings, and behavior that contribute to somatic symptoms. The cognitive component of the treatment focuses on helping patients identify dysfunctional thinking about physical sensations. With practice, patients learn to recognize catastrophic thinking and develop more rational explanations for their feelings. The behavioral component aims to increase activity. Patients with somatization disorder have usually reduced their activity levels as a result of discomfort or out of fear that activity will worsen symptoms. CBT patients are instructed to increase activity gradually while avoiding overexertion that could reinforce fears. Other important types of treatment include relaxation training, sleep hygiene, and communication skills training. Preliminary findings suggest that CBT may help reduce distress and discomfort associated with somatic symptoms; however, it has not yet been systematically compared with other forms of therapy.

Medications

Antidepressant medications may help to alleviate symptoms of somatization disorder. According to one study, patients with somatization disorder who took the antidepressant nefazodone (Serzone) showed reductions in physical symptoms, increased activity levels, and lower levels of anxiety and depression at the end of treatment.

Prognosis

Untreated somatization disorder is usually a chronic condition, though specific symptoms can come and go and overall severity may fluctuate over time. Somatization disorder poses a serious problem for society, since many who suffer from it become functionally disabled and unable to work. In addition, patients with unexplained physical symptoms strain already overburdened health care resources. Unexplained physical symptoms are extremely common among patients visiting general practitioners, with some estimates suggesting that over two-thirds of general medical patients have symptoms that cannot be explained by medical tests. Fortunately, there is preliminary evidence that psychotherapy and medication can effectively reduce symptoms and disability.

Prevention

Greater awareness of somatization disorder, particularly among physicians, can help them identify individuals with somatization disorder, and help these patients get appropriate psychological or psychiatric treatment.

This description sounds so much like my past couple of years. In late 06 presented with 4 to 5 voids/night, not getting sleep, always tired, difficult to exercise. This lead to finding Prostate cancer, PSA 10 to 14, G 8-9, all 12 cores 5 to 70% cancer. Began ADT June 07, EBRT/IMRT was suggested and performed Sept-Oct 07. Third week of treatment, going to toilet #1 & #2 very painful, wanted to quit, given valium & Vicoden, was off meds by mid Nov 07. Other complications extended pain through March-April 08. Off ADT June 08. Sept 08, Argon laser cauterazation of rectum with weak anus, colitis, still have blood in stool, still voiding 4-5 times/night. Late Sept 08, diagnosed Major, single, Depression. Started Prozac 10 mg, ten days later, suddenly only up once/night. Doc is suggesting that my anxiety during the day caused the kidneys to slow production, then at night when I relaxed (read that, turn off conscience mind)the kidneys would ramp to 200 to 300 cc every 1 to 1.5 hrs. Still experiencing depression, up dose to 20 mg/day, very few down moods now.

My sister has multiple symptoms that suggest she has somatization disorder. She freaks out anytime someone suggest she see a psychologist and yet non of the dozens of doctors she has seen are able to properly diagnose her condition. How does my family go about getting her the help she needs?

Lulu, It sounds like what you may be experiencing is conversion disorder, a kind of somatiform disorder brought on by stress or trauma. Seek a mental health professional for diagnosis and treatment so that you can resume your life. There is hope and help for you.

My wife was diagnosed. with this disorder. and our son has essentially abandoned her in her greatest time of need for support. For all practical purposes my some considers his mom already dead which only makes the whole situation that much more tragic. I feel completely inadequate as a husband and father. I he had 3 kidney transplants myself which for us were easy to handle. but what my wife is going through feels 1,000 times tougher to handle. my heart is completely broken.

I "woke" up completely, agramatical, aphasiac: a year ago. I also had cognitive issues including short-term memory.

I've had imaging tests, all negative.

My speech is better.. But still causes me so much strain. I'm disfluent and have word retrieval problems. The cognitive issues remain.

I'm recieving Thearpy.. But I feel like I've lost,"ME" who "I am." My intelligence. My "dry-sence" of humor, particularly any application of it..

I've had chronic pain, previously, back; I don't know if related. But having physical AND trouble communicating.. It's just unacceptable.. I don't see any clearcut ways of relief.. Cure.. I wander daily, with the possibility of being "attacked" again, of practically no speech.

I am trying positive thing, meditation, therapy.


It "feels" like, no ones particularly alarmed, as if it were stroke & no true road of recovery.. To ME this is an emergency! This is ME, we're loosing... My intellect, conversations, organization abilities..

I'm really just, scared as hell, underneath it all. The point, mentioned that conversion patients aren't very concerned over their symptoms, surely, doesn't fit me.

I'm in Southern Maine. I don't know of any other options or clinicians near here, that can provide, the "hope and treatment" mentioned to the prior public comment..

I don't know if this makes sense, exactly. I seem to use "stories" now, to explain thoughts. I'm a college graduate that has lost much of my previous skills...

Weary, weary, Conversion Disorder Aphsiac Patient.. (who wants to be the intelligent, witty, talented Woman she was.)

This was hard to "expose" this is my truth. This is conversion disorder..

one month back, my wife had operation of removing tonsils. Now complaints that she has pain in jawline, headache, neck pain and some times she say i cannot feel my body(but she can walk easily and do normal activities). She reviewed the operating doctor, doctor say there is know problem at all.
is it due to somatization disorder?
