Perchlorate reduces thyroid function in women, may lead to dry, puffy skin

A new study of perchlorate, a chemical commonly used in rocket fuel, pyrotechnics, road flares and explosives has been shown to slow down thyroid function in women. Perchlorate is widespread in the US, and is found in drinking water, ground water, and foods, including milk, grains, vegetables, and fruit.

The Centers for Disease Control (CDC) found that high levels of perchlorate led to low thyroid functioning in women, but not in men. The women who were most effected had low iodine intake.

This is important because perchlorate could be one pathway to developing hypothyroidism, which is a medical condition resulting from diminished thyroid function. People with hypothyroidism tend to have dry, puffy skin, weight gain, fatigue, mental slowdown, and other symptoms. They may also show yellowing of the skin due to problems converting beta carotene to vitamin A.

This study was completed on 2300 people, and a larger follow up study is currently underway.

If you are troubled by the symptoms of hypothyroidism, including dry, puffy, or yellowing skin, please seek medical advice immediately.
