Exposure to some Pfas could increase risk of multiple miscarriages – study | Women’s health

Exposure to certain toxic PFAs “forever chemicals” can increase the risk of making several false layers, has revealed new research evaluated by peers.

The study, which followed around 200 women in China, revealed that those who had at least had two false layers, or unexplained recurrent spontaneous abortions, have shown higher levels of several types of APF in their blood. The study adds to a long list of reproductive damage associated with exposure to PFAs.

“Previous studies have identified that the PFAs were associated with unfavorable results of pregnancy, but the potential influence of the PFAS exposure on [recurrent miscarriages] remained uncertain, “wrote the authors of the study, with the Chinese Center for Disease Control and Prevention.” Our survey has identified significant associations between [some Pfas] And the increased risks of unexplained recurrent spontaneous abortions. »»

PFAs are a class of approximately 16,000 chemicals generally used to make products that withstand water, stains and heat. They are called “chemicals forever” because they do not decompose naturally and do not accumulate in humans and the environment. Chemicals are linked to cancer, kidney disease, liver problems, immune disorders and other serious health problems.

Some PFAS compounds are linked to development problems such as congenital malformations and low birth weight. In men, it is believed that chemicals lower the quality of sperm and cause DNA changes that can have an impact on the health of progenitors later in life.

According to the American College of Obstecians and Gynecologists, around 5% of women have recurrent false layers and half of them have no explanation.

Among the chemicals that showed the strongest association were PFHX, which is a common PFAS water pollutant. Several of the compounds for which researchers found associations were “short chain” APFs, which means that small chemicals which, according to industry, are generally safer and less toxic than the older and larger APFs.

However, there is little independent research on many short channels, but what exists indicates high toxicity, and new research adds to increasing concerns about their safety.

The biological mechanism by which the PFA can cause false layers is not clear, wrote the authors, but they have theorized that it had to do with the disturbance of normal thyroid hormonal metabolism and other hormonal impacts. PFAs are strongly associated with the damage to the endocrine system. The authors wrote that follow -up research is necessary to examine the issue and find solutions and said that a larger cohort size should be studied to confirm their results.

Research adds to “an incredible set of evidence linking the exposure to APF to the damage to development,” said David Andrews, principal scientist of the non -profit environmental working group that follows PFAS problems, but was not involved in the study.

“This is a shocking impact on health and it also indicates that these compounds seem to be wreaking havoc in our body,” said Andrews.

PFAs are omnipresent in consumer goods and the environment, so they are difficult to avoid. But women can protect themselves using filtration systems that eliminate water PFAS, avoiding non -stick kitchen utensils, avoiding dyes, purchasing organic food and looking for cosmetics without PFAS or personal care goods.
