An approach to Multiple Chemical Sensitivity

Multiple Chemical Sensitivity (MCS) is a term used to describe people with psychosomatic symptoms due to environmental factors. It is also called environmental illness. They are generally seeking for benefits from their employer, and may be related to workers' compensation.  Some review however state that MCS is not a valid diagnosis and there is no clear evidence regarding this disease.

In my view, in approaching a person with MCS, a cautious and sympathetic exposure and psychosocial history assessment is imperative. In this situation patient tend to be frustrated due to seeking advice and counsel regarding treatment and often getting lack of definitive answer about the disease. It will be not helpful if approaching the patient with the suspicion that this is a psychiatric condition. The patient's symptoms should be acknowledged and a trusting relationship should be established.

Although the physical examination is often normal, the symptoms with particular attention to respiratory, neurology and systemic systems and onset in relation to chronic or acute exposures should be investigated to obtain the occupational history of the disease.

It is important to explain what is known and what is not known about MCS. Patients should be advised that the treatment for MCS just like other chronic diseases is not directed at a cure but more at the adjustment. Relieving the symptoms is also important, but more importantly to ensure that return to active work and social life will be more helpful. Then, clinicians should provide regular follow up to help patients cope with the problems.
