Study links thyroid disease to non

LONDON canada goose uk outlet (Reuters) Scientists have linked a chemical used in consumer goods like non stick pans and water resistant fabrics with thyroid disease, Canada Goose Parka raising questions about the potential health risks of exposure to the substance.

A study by British researchers found that people uk canada goose with high levels of the chemical perfluorooctanoic acid (PFOA) in their blood have higher Canada Goose Outlet rates of thyroid diseases conditions which affect buy canada goose jacket cheap the body metabolism.

PFOA is a common canada goose clearance chemical, used in industrial and consumer products including non stick cooking cheap Canada Goose pans, stain proof carpet canada goose store coatings and waterproofing Canada Goose Jackets for fabrics.

The study, published in the Environmental Health Perspectives journal, did not establish whether PFOA was uk canada goose outlet causing higher levels of thyroid disease.

The researchers said the link might be complex and indirect, canada goose factory sale and added that their work highlighted a canadian goose jacket need for further studies of the human canada goose health effects of low level exposures to chemicals like PFOA.

need to know what they (these chemicals) are doing, canada goose Canada Goose Outlet coats on sale said Tamara Galloway, a professor of canada goose clearance sale ecotoxicology Canada Goose Online at Exeter University, who led the research.

Previous studies of people living near sites where PFOA is manufactured have not found an association between exposure to these chemicals and thyroid function, and some other scientists advised caution about drawing conclusions from the study.

INDIRECT LINK? Canada Goose sale like this cannot Canada Goose online tell us that the two things are definitely linked, said Ashley Grossman, professor of neuroendocrinology at Queen Mary, University of London.

also don know whether this chemical is directly affecting the thyroid. Thyroid disease is often caused by the body own immune canada goose coats system attacking the thyroid gland so perhaps this chemical is having some effect on the immune system, rather than directly on the thyroid.

The thyroid, located in the neck, is a kind Canada Goose Coats On Sale of master gland, secreting hormones affecting metabolism. People with low thyroid function may lose hair, gain weight and feel sluggish, while those with overactive thyroids may lose weight and feel their hearts race. Both conditions can be treated.

The British researchers looked at 3966 American adults aged 20 and above whose blood serum was sampled between 1999 and 2006 for PFOA. They found that those with the highest PFOA concentrations (above 5.7 nanograms per milliliter) were more than twice as buy canada goose jacket likely to report current thyroid disease than individuals with the lowest levels (below 4.0ng/ml).

Thyroid diseases are much more common in women than men, but in terms of the link between PFOA and thyroid disease, the researchers found no difference between the sexes.

Galloway and colleagues stressed the need for more work but said their canada goose black friday sale study suggested it is that cheap canada goose uk the compounds could disrupt binding of thyroid hormones in the blood or alter their metabolism in the liver.

new evidence does not rule out the possibility that having thyroid disease changes the way the body handles canada goose uk shop PFOA, they added, and canada goose uk black friday its presence also prove to be simply a marker for some other factor associated with thyroid disease.
