Polysomatic complaints or disorders with a subjective feeling of elicitation by environmental influences are a serious problem in the physician's practice because of the lack of established etiopathophysiology as well as of diagnostic and therapeutic strategies. Whether the symptoms of these patients are best characterized as an organic disorder, a psychological disorder, or a combination of both, is still discussed. Based on several studies consistent physical or laboratory findings do not exist and there is no evidence for a toxic origin of complaints. The patients described under the terms "Idiopathic Environmental Intolerance", "Multiple Chemical Sensitivity" (MCS), "Eco-Syndrome" and others seem to be a heterogeneous group. Somatic disorders including allergic reactions and non-immunologic hypersensitivity reactions (idiosyncrasy, intolerance, pseudo-allergic reactions) have to be excluded. Several studies showed an increased rate of psychosomatic-psychiatric stress disorders (somatoform disorder, depressive disorder, posttraumatic stress disorder, panic attacks, or a combination of several diagnoses) in which the manifestation of symptoms is seen together with actual or perceived exposure to chemicals. The treatment depends on the results of an interdisciplinary diagnostic procedure.
