Here the result of medical test are either normal or fails to explain the person’s symptoms.And the history and physical examination do not reveal any known medical condition.

Dignosis:-

It is quite a challenge to work with somatoform disorder it requires considering a mental health diagnosis while excluding the medical causes of the physical symptoms.The problem with these type of disorder is the that there is no specific physical examination or laboratory finding that are required for confirmation of the diagnosis.Though appropriate non psychiatric medical condition should be considered by unnecessary laboratory testing should be avoided in such cases.Factitious disorder and malingering though are related disorders should be excluded before diagnosing a somatoform disorder . In factitious disorder the patient has a internal desire to be sick , while in malingering the patient bluff the physical symptoms so that he may have any sort of gain such as financial benefit ,legal benefit , escaping a unfavorable situation. But in somatoform disorder, there is no possible gain for the patient and the physical symptoms are not feigned , rather fear and anxiety stimulates these disorders.

The diagnosis of Somatoform disorders have been assisted by clinical diagnostic tools such as patient health questionnaire .

If the patient is bothered a lot lot by at least three of the symptoms without a medical reason then there is a possibility of somatoform disorder.
Treatment-

The patient have a strong believe that their symptom have a physical cause , though is is contrary .This is due to the false interpretation of the symptoms.
The steps of the treatment are-
1. Discussing the key features of the diagnosis with the patient-
The initial steps in the treatment is to discuss about the disorder to the patient early in the work-up and, after ruling out organic pathology as the primary ethology for the symptom, to confirm the psychiatric diagnosis.The physician must first construct a therapeutic alliance with the patient.then the physician must review with the patient the therapeutic criteria for the suspected somatoform disorder. He must inform the patient that the goal of treatment is management rather than cure.
2. Therapy-
First and foremost is the treatment of the psychiatric comorbidities , since the psychiatric disorders are generally found in union with the co morbidities.
There is limited effectiveness of the pharmacological interventions.
Cognitive behavior therapy have been found to be effective in the somatoform disorder.It focuses on reducing cognitive distortions , imaginary belief , worry and behavior that lead to anxiety and somatic manifestation.

3. Follow up-
Regular and brief follow up with the physician is an important aspect of treatment.This is important for the maintainable of the therapeutic alliance with the physician .The patient can openly ventilate about their worries and the opportunity to be reassured repeatedly that their symptoms are not due to a physical condition

Practice Management Strategies for Somatoform Disorders:-
Accept that patients can have distressing, real physical symptoms and medical conditions with coexisting psychiatric disturbance without malingering or feigning symptoms
Consider and discuss the possibility of somatoform disorders with the patient early in the work-up, if suspected, and make a psychiatric diagnosis only when all criteria are met
Once the diagnosis is confirmed, provide patient education on the individual disorder using empathy and avoiding confrontation
Avoid unnecessary medical tests and specialty referrals, and be cautious when pursuing new symptoms with new tests and referrals
Focus treatment on function, not symptom, and on management of the disorder, not cure
Address lifestyle modifications and stress reduction, and include the patient’s family if appropriate and possible
Treat comorbid psychiatric disorders with appropriate interventions
Use medications sparingly and always for an identified cause
Schedule regular, brief follow-up office visits with the patient (five minutes each month may be sufficient) to provide attention and reassurance while limiting frequent telephone calls and “urgent” visits
Collaborate with mental health professionals as necessary to assist with the initial diagnosis or to provide treatment
