Multiple chemical sensitivity (MCS), also known as idiopathic environmental intolerances (IEI), is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of common chemicals. Symptoms are usually vague and nonspecific. They may include fatigue, headache, nausea and dizziness.


Although these symptoms can be debilitating, MCS is not recognized as an organic chemical-induced disease by the World Health Organization, the American Medical Association, nor by any of the many other professional medical organizations. Blinded clinical trials show that people with MCS respond as often and as strongly to placebos as to chemical stimuli; the existence and severity of symptoms is seemingly related to the perception that a chemical stimulus is present.


Commonly attributed substances are fragrance products (e.g., perfumes), pesticides, plastics, synthetics, smoke, petroleum products and paint fumes.


Treatment BeterKlinic

BeterKliniek is the clinic for Integrative Medicine that bridges regular and non-regular medicine.

An van Veen (physician) and Michael van Gils (therapist) look for the cause of a condition or disease. That is where the treatment starts otherwise, as people often say, it is 'carrying water to the sea'. We call this cause medicine. Sometimes it is also desirable to treat the symptoms (at the same time). We call this symptom medicine.

Chronic disorders often have their cause in epi- genetics. You can schedule a free informative telephone consultation (phone number 040-7117337 until 1 p.m.) at BeterKliniek to discuss your symptoms so that we can provide you with further advice.
