You Excessive Fluoride May Cause Thyroid Dysfunction
Studies into the effects of excessive fluoride exposure have had mixed results, but some evidence suggests that fluoride can interfere with the function of the thyroid. This gland produces hormones that control many important body functions, including growth, digestion, body temperature, and heart rate. An underactive thyroid, called hypothyroidism, occurs when the thyroid doesn’t produce enough hormones. Hypothyroidism can cause fatigue, weight gain, muscle soreness, depressed mood, loss of sex drive, and brain fog. One study found that people in areas with drinking water fluoridation are at higher risk of developing hypothyroidism than people in areas without the policy. This study was controversial as it contradicted the findings in previous studies, suggesting that more research is needed to determine if there is a link between fluoride and thyroid dysfunction. A more recent study found that fluoride exposure may increase the risk of hypothyroidism in pregnant women.
