Background
Hypochondriasis and the other somatoform disorders are among the most difficult and most
complex psychiatric disorders to treat in the general medical setting. On the basis of manynew developments in this field, diagnostic criteria have been revised to facilitate clinical care

and research. Long-awaited randomized, placebo-controlled treatment approaches have
finally emerged. Comparative clinical effectiveness studies are also being developed.
As with all psychiatric disorders, the somatoform disorders demand creative, rich
biopsychosocial treatment planning by a team that includes primary care physicians,
subspecialists, and mental health professionals.[1]
This article describes hypochondriasis, its diagnosis, and an overview of treatment
approaches, with references for details beyond the scope of the article. Finally, the article
reviews new developments in psychopharmacologic and psychotherapeutic treatments.
Case study
A 45-year-old white male engineer presents to a primary care clinic armed with multiple
internet searches on the topic of cancer. He states that he “just knows” he has a GI cancer,
"probably the colon or maybe the pancreas." When asked how long this concern has bothered
him he says "for years I have been concerned that I have cancer." You ask about relevantsymptoms and he is a bit vague, saying "I get some pain or pressure right here (he points to
the left upper quadrant) but it is not there all the time." Upon asking about prior workups he
says “I have had ultrasounds and colonoscopies but they could find anything. I was initially
relieved but a couple of weeks later started to think that they must have just missed
something.”
When you ask about the patient's goals for today’s visit he is emphatic "I think what I really
need is another colonoscopy and abdominal CT scan." His examination is unrevealing. When
you suggest a less invasive approach, he shows the error rates of the other evaluations and
shows literature endorsing how abdominal CT is the criterion standard. He is anxious at
baseline and increasingly irritable when you propose less invasive evaluation. He ends the
encounter by stating that he will “find another doctor who sees my point and will get me what
I need.”

Pathophysiology
Neurochemical deficits associated with hypochondriasis and some other somatoform
disorders (eg, somatization, conversion, and body dysmorphic disorders) appear similar to
those of mood and anxiety disorders. See Medscape Reference articles Somatoform Disordersand Conversion Disorders.
For example, Hollander et al posited an "obsessive-compulsive spectrum" to include
obsessive-compulsive disorder (OCD)[2, 3] , body dysmorphic disorder (BDD), anorexia
nervosa, Tourette syndrome, and impulse control disorders (eg, trichotillomania, pathological
gambling).[4] Other authors postulate that somatoform disorders including hypochondriasis
may be a learned unconscious behavior that may serve to avoid internal conflicts and external
stressors.[5]
This formulation of obsessive-compulsive (OC) spectrum disorders, while not a part of the
consensus psychiatric diagnostic and classification literature, crosses boundaries of severaldiagnostic categories in the Diagnostic and Statistical Manual of Mental Disorders, Fourth
8/10/2019 contoh referat medscape.docx
http://slidepdf.com/reader/full/contoh-referat-medscapedocx 3/23
Edition-Text Revision ( DSM-IV-TR). In addition, encountering a patient with more than one
of the anxiety spectrum disorders during his or her life is not unusual. Although findings of
studies of these neurochemical deficits are only preliminary, such deficits may explain why
symptoms overlap, why the disorders are commonly comorbid, and why effective treatments
parallel one another (eg, selective serotonin reuptake inhibitors [SSRIs]).
In a recent study of biological markers, subjective who met DSM-IV-TR diagnostic criteria
for hypochondriasis had decreased plasma neurotrophin 3 (NT-3) level and platelet serotonin
(5-HT) levels, compared to healthy control subjects. NT-3 is a marker of neuronal function
and platelet 5-HT is a surrogate marker for serotonergic activity. [6]

Epidemiology
Frequency
United States
The prevalence rates for primary hypochondriasis in the primary care setting are 0.8-
4.5%.[7] Some degree of preoccupation with disease is apparently common, because 10-20%
of people who are healthy and 45% of people without a major psychiatric disorder have
intermittent unfounded worries about illness.[8]
International
International rates are similar to those in the United States.[9]
Mortality/Morbidity
Hypochondriasis is usually episodic, with hypochondriacal symptoms that last from months
to years and equally long quiescent periods. Although formal outcome studies have not been
conducted, one third of patients with hypochondriasis are believed to eventually improve
significantly. A good prognosis appears to be associated with high socioeconomic status,
treatment-responsive anxiety or depression, the absence of a personality disorder, and the
absence of a related nonpsychiatric medical condition. Most children are believed to recover
by adolescence or early adulthood, but empiric studies have not been carried out.
Epidemiological studies are lacking, but patients with hypochondriasis appear similar to those
with somatization disorder. These individuals use medical care at high rates, making frequent
visits to the emergency department, the doctor, and other health care providers and
undergoing frequent physical examinations, laboratory testing, and other costly, invasive, and
potentially dangerous procedures.[10]
Cognitive, social learning, and psychodynamic theories imply that patients have significant
psychosocial disturbances in terms of relationships, vocational, and other endeavors.
Exacerbations may occur with psychological stressors and in patients with comorbid
psychiatric conditions.

These high-use patterns differ dramatically from those of nonsomatizing patients and remain
true even when comorbid medical conditions and sociodemographic differences are
accounted for.[11] The medically unexplained complaint is often a symptom of
hypochondriasis[12] and may well be a presentation of associated abnormal illness
behavior.[13]
Patients with hypochondriasis have a high rate of psychiatric comorbidity.[14] In one general
medical outpatient clinic, 88% of patients with hypochondriasis had one or more concurrent
psychiatric disorders, the most common being generalized anxiety disorder (71%), dysthymic
disorder (45.2%), major depression (42.9%), somatization disorder (21.4%), and panic
disorder (16.7%). These patients are 3 times more likely to have a personality disorder than
the general population.[14] Substance abuse or dependence is also a serious comorbid
condition, particularly use of benzodiazepines, though epidemiological studies have not
assessed the exact frequency of this problem. The long-term prognosis of patients with
hypochondriasis is understudied due to the heterogeneity of the disorder. However, higher
severity at baseline is likely associated with worse outcome.
Race
This disorder has not been well studied with respect to race and ethnicity. More information
is needed, too, with regard to its relationship to other medical disorders needing better
definition (eg, neurasthenia, chronic fatigue syndrome, fibromyalgia, and multiple chemical
sensitivity syndrome).
Sex
Hypochondriasis appears to occur equally in men and women.
Age
Hypochondriasis can begin at any age, but the most common age of onset is early adulthood.
References
History
Hypochondriasis is classified as one of the somatoform disorders, a class that was formulated
to accommodate the differential diagnosis of disorders characterized primarily by physicalsymptoms for which no demonstrable organic explanations or physical findings exist.
The DSM-IV-TR stipulates that the symptoms are not under voluntary control (thus excluding
malingering and factitious disorders) and are not fully explained by known physiological
causes (excluding psychological factors affecting the medical condition). The disorders in the
somatoform class include somatization disorder, conversion disorder, pain disorder,
hypochondriasis, BDD, and undifferentiated somatoform disorder.
The core feature of hypochondriasis is not preoccupation with symptoms themselves, but
rather the fear or idea of having a serious disease (see the image below). The fear or idea is
based on the misinterpretation of bodily signs and sensations as evidence of disease. The
illness persists despite appropriate medical evaluations and reassurance.

Pathological cycle of bodily concern and anxiety in hypochondriasis.
The diagnosis should be considered strongly if the patient has a history of hypochondriasis
(or other somatization disorder) or has had multiple nonproductive clinical workups, and ifthe patient's complaints are markedly inconsistent with objective findings or the examination
yields no abnormal findings. Further psychiatric history should be obtained with regard to a
history of hypochondriasis (or corresponding behaviors) in family members or a sudden,
unexplained loss of function that spontaneously resolved.
Diagnostic criteria for hypochondriasis include the following ( DSM-IV-TR):
The patient has a preoccupying fear of having a serious disease.
The preoccupation persists despite appropriate medical evaluation and reassurance.
The belief is not of delusional intensity (as in delusional disorder, somatic type) and is
not restricted to a concern about appearance (as in persons with BDD). The preoccupation causes clinically significant distress or impairment.
The preoccupation lasts for at least 6 months.
The preoccupation is not explained better by another mood, anxiety, or somatoform
disorder.

Physical
The absence of physical findings, particularly after serial examinations, supports the
diagnosis of hypochondriasis. However, the patient must receive a physical examination to
make the psychiatric intervention possible. A mental status examination complements the
physical examination.

Causes
Developmental and other predisposing factors (see the image below) consistently indicate the
importance of parental attitudes toward disease, previous experience with physical disease,
and culturally acquired attitudes relevant to the etiology of the disorder. [15] Overall however,
few demographic and clinical differences have been found between patients with
hypochondriasis and the general population. Social position, education level, and marital
status do not appear to be factors in this condition.

Mood, cultural, developmental, and environmental factors that influence
hypochondriasis.
A cognitive model of hypochondriasis suggests that patients misinterpret bodily symptoms by
augmenting and amplifying their somatic sensations. Patients also appear to have lower-than-
usual thresholds for, and tolerance of, physical discomfort. For example, what most people
normally perceive as abdominal pressure, patients with hypochondriasis experience as
abdominal pain. When they do sustain an injury (eg, ankle sprain), it is experienced with
significant anxiety and is taken as confirmation of their worry about being ill. This may be
due to a tendency among patients with hypochondriasis to exaggerate their assessment of
vulnerability to disease and their appraisal of the risk of serious illness.[11]
The social learning theory frames hypochondriasis as a request for admission to the sick role
made by a person facing seemingly insurmountable and insolvable problems. This role may
allow them to avoid noxious obligations, postpone unwelcome challenges, and be relieved
from duties and obligations.[16]
The psychodynamic theory implies that aggressive and hostile wishes toward others are
transferred via repression and displacement into physical complaints. The hypochondriacal
symptoms serve to "undo" guilt felt about the anger and serve as a punishment for being
"bad."
Neurochemical deficits with hypochondriasis and some other somatoform disorders (eg,BDD) appear similar to those of depressive and anxiety disorders. For example, in 1992,
8/10/2019 contoh referat medscape.docx
http://slidepdf.com/reader/full/contoh-referat-medscapedocx 8/23
Hollander et al posited an obsessive-compulsive spectrum that includes OCD, BDD, anorexia
nervosa, Tourette syndrome, and impulse control disorders (eg, trichotillomania, pathological
gambling).[4] Although only preliminary data have been reported on these neurochemical
deficits, such deficits may explain why symptoms overlap, why the disorders are commonly
comorbid, and why treatments may parallel one another (eg, SSRIs).
Hypochondriasis has been hypothesized to be an anxiety spectrum disorder. P-wave
dispersion (the difference between the maximum and minimum P-wave duration on the
electrocardiograph) has been found to be significantly higher in patients with panic disorder
and in patients with hypochondriasis, compared with healthy control subjects. The elevated
P-wave dispersion may be an indicator of cardiac autonomic dysfunction in anxiety
disorders.[17]

Due to the enigmatic nature of various physical symptoms, occasionally patients with
hypochondriasis are admitted to the general medical-surgical hospital for an extensive work-
up.
When hypochondriasis is suspected in a medical or surgical inpatient, a psychosomatic
medicine consultation should be performed to elucidate the diagnosis and address psychiatriccomorbidity.
If clinically recommended by the psychosomatic medicine consultant, psychotropic
medication interventions can be started.
As in the outpatient care model, patients should not be exposed to high-risk invasive
procedures.
Numerous other strategies appear to benefit patients with hypochondriasis (see the image
below). These strategies may prevent potentially serious complications, including the effects
of unnecessary diagnostic and therapeutic procedures.
View ImageFactors that maintain anxiety in patients with hypochondriasis.
Establish one primary care physician as the patient's main physician.
Review the patient's medical history to build an alliance and rule out medical disorders.
Premature reassurance, prescription of psychotropic medications, and referral for mental
health services may suggest to the patient that he or she is not being taken seriously.
Therefore, while such treatments may be indicated at some time (in the future), prematurely
offering a diagnosis or psychiatric treatment may, in fact, impair the establishment of a
trusting patient-physician relationship.
Acknowledge the patient's pain and suffering.
Couple reassurance statements of normal findings with statements that that the patient will
not be abandoned. For example, “Mr. Smith, it appear s that you are still having concern about
having a “several medical disorder” despite all the workup, which, so far, has not showed any
abnormal finding. I will continue to work with you to maximize you overall well-being andhealth.”
Reassure the patient that evaluation will be ongoing.
Understand the “the fear” of having an unknown medical disorder as a form of emotional
communication.
Search for underlying medical and psychiatric disorders potentially amenable to treatment.
Seek consultation or refer the patient to a colleague if establishing an alliance proves
difficult.

Allow for time-limited structured discussions about somatic concerns.
Spend sufficient time on health care maintenance issues such as diet, experience, smoking
cessation, and cancer detection.
Treat comorbid psychiatric disorders concurrently.
Be aware of emotional reactions toward the patient (ie, anger, hopelessness, helplessness) and
seek frequent informal consultation when possible.
Focus on care of the patient with hypochondriasis, not exclusively on “a cure” for the
disorder.
Psychotherapy
Several authors have suggested a cognitive-educational approach to understand the
development of the severe anxiety associated with hypochondriasis (see thefirst image below)and the factors that maintain the long-term anxiety (see the second image
below).[39] Randomized controlled trials now suggest that cognitive-behavioral therapy (CBT)
is efficacious in the treatment of hypochondriasis[40, 41, 42, 43, 44] and may be the recommended
treatment for patients with hypochondriasis. Bibliotherapy, using CBT principles, may also
be useful.

Surgical Care
Psychosurgery is only recommended for patients with severe and intractable hypochondriasis.
References
Consultations
Primary care physicians generally treat hypochondriasis, with psychiatrists providing
consultation.
References
Diet
Patients with hypochondriasis should eat 3 meals per day to feel as healthy as possible. They
should avoid substances that adversely affect mood, exacerbate anxiety symptoms, or reduce
the quality of sleep (eg, caffeine, alcohol, nicotine).

Activity
Exercise increases psychological well-being. Patients who are hypochondriacal may bereluctant to follow this advice, but many patients greatly increase their physical activity as

Class Summary
These are typically used for depression or anxiety comorbid with hypochondriasis, although
in some cases they alleviate hypochondriacal symptoms in the absence of another disorder.
They are indicated for use in adults with depression, anxiety (eg, panic disorder, OCD, social
phobia, generalized anxiety, posttraumatic stress disorders), and bulimia nervosa disorders.
Off-label uses include insomnia, attention-deficit/hyperactivity disorder, premenstrual
dysphoric disorder, and other conditions. All SSRIs (eg, fluoxetine [Prozac], sertraline
[Zoloft], paroxetine [Paxil], citalopram [Celexa], escitalopram [Lexapro], fluvoxamine[Luvox]), one selective norepinephrine and serotonin inhibitor (ie, venlafaxine [Effexor
XR]), 2 TCAs (ie, clomipramine [Anafranil], imipramine [Tofranil]), and one MAOI (ie,
tranylcypromine [Parnate]) have been listed; the latter should be used with care because of
dietary restrictions and drug interactions. Data on bupropion (Wellbutrin) and mirtazapine
(Remeron) are insufficient to warrant listing, but they may also be used.
Initial doses are listed below. The general principle in these patients is to start at a low dose
and progress slowly, unless a psychiatric emergency (eg, suicidal ideation) is present. Once
established, a well-tolerated and efficacious antidepressant should be continued as indicated
for the comorbid condition (eg, 6-12 mo for a single depression or indefinitely for recurrent
depression and an anxiety disorder). If used for hypochondriasis alone, for maintenance

Have been shown to reduce morbidity associated with this disorder, particularly in presence
of comorbid anxiety or hypochondriacal worries that mimic obsessions or delusions. Because
of potential for serious long-term adverse effects (eg, tardive dyskinesia), consultation with
psychiatrist recommended to evaluate need for antipsychotic medication. Insufficient data to
list other antipsychotics, although they have been used in patients with hypochondriasis.

For patients with comorbid disorders, consider maintenance of those trials because
these disorders can initiate and/or exacerbate hypochondriacal symptoms.
References
Transfer
Physician-to-physician dialogue on the nature of the patient's problems and successful
management strategies is useful.
References
Complications
Patients who are hypochondriacal may be significant consumers of medical care,
undergoing repetitive doctor visits, physical examinations, laboratory testing, and
other costly, invasive, and potentially dangerous procedures. Physician concerns regarding workups for somatic complaints also may preclude
diagnosis of common comorbid disorders (eg, depression) that are quite treatable.
References
Prognosis
Hypochondriasis is a common disorder in primary care settings.
The differential diagnosis includes other somatoform, depressive, anxiety (eg,
generalized anxiety disorder, OCD), and psychotic disorders. Biopsychosocial treatment is required to manage this complex disorder, and further
research is required to better understand its pathophysiology and interface with other
psychiatric conditions. Recognizing the biological similarities between these
seemingly disparate disorders may be a useful starting point to begin a more
systematic study of novel treatments for hypochondriasis.[46]
A system review of six studies on hypochondriasis indicated that 30-50% of patients
achieve recovery.[47]
A good prognosis appears to be associated with high socioeconomic status, treatment-
responsive anxiety or depression, the absence of a personality disorder, and the
absence of a related nonpsychiatric medical condition.
Most children recover by adolescence or early adulthood. There is a dearth of long-term follow-up studies examining outcomes of patients with
hypochondriasis. In a prospective study that examined 58 patients with
hypochondriasis who had participated in selective serotonin reuptake inhibitor (SSRI)
treatment for 4-16 years (mean 8.6±4.5 y), 40% continued to meet the diagnosis of
hypochondriasis. Predictors of continued diagnosis of hypochondriasis include longer
duration of hypochondriasis prior to treatment, history of childhood physical
punishment, and lower use of SSRI during the treatment period. A large portion of
patients with hypochondriasis who received SSRI treatment were able to achieve
remission.[48]
