Subject: Biology | Topics:

Idiopathic environmental intolerance (IEI), also called multiple chemical substance sensitivity, is a subjective illness noticeable by recurrent, nonspecific symptoms assigned to low levels involving chemical, biologic, or physical agents. These symptoms occur inside the absence of constant objective diagnostic real findings or laboratory tests that define an illness. Symptoms are normal, but vague and non-specific for the condition, such as nausea, fatigue, dizziness in addition to headaches.
