Fluoride exposure during pregnancy has been found to lead to lower IQ scores and hypothyroidism in children, according to new research.

The study, published in Environmental Health Perspectives, examined data from 299 pregnant women and their children over a period of 12 years.

What is Fluoride?

Fluoride is a chemical compound that is commonly added to drinking water and dental products in order to reduce tooth decay.

However, excessive exposure to fluoride can cause health problems, including hypothyroidism and lowered IQ, as well as dental fluorosis and skeletal fluorosis.

The Study

The study looked at the levels of fluoride in the urine of pregnant women, and then monitored their children’s cognitive development and thyroid function for 12 years.

The researchers found that higher levels of fluoride in the urine of pregnant women was associated with lower IQ scores in their children, particularly in areas such as memory and visual-spatial abilities. The higher fluoride levels were also linked to an increased risk of hypothyroidism in the children.

What is Hypothyroidism?

Hypothyroidism is a condition in which the thyroid gland, located in the neck, does not produce enough thyroid hormone. This can lead to a range of symptoms, including fatigue, weight gain, constipation, and depression.

Hypothyroidism is particularly harmful in children, as it can cause developmental delays and problems with growth and cognitive function.

How to Reduce Fluoride Exposure

While fluoride is added to drinking water in order to prevent tooth decay, excessive exposure can be harmful to health. Here are some tips for reducing fluoride exposure:.
