A study found that hundreds of abnormal menstruations were reported after exposure to tear gas

Last summer, protesters at the Kaiser Permanente Health Research Center in Portland, Port Harcourt, had a series of reports of abnormal menstrual cycles after they were exposed to tear gas to dismiss them. Incidentally.

Preschool teacher He told Oregon Public Broadcasting If she inhales a large amount of gas at night, she will have her period the next morning. other Portland residents shared stories Weeks old and unusual spots. Transgender men report periods of resistance to menstrual hormones Months Or Years

Dr. Torgrimson: Ojerio decided that she would try to find out if these stories were representative of a very common phenomenon. She surveyed some 2,200 adults who reported exposure to tear gas in Portland last summer. as if Study This week at BMC. She published in the Journal of Public Health, of which 899 reported that they had more than 54 percent of irregular menstrual cycles.

Dr. Torgrimson: Ojerio: We can’t say anything scientifically about these chemical agents and the causes of menstrual irregularities. After reporting exposure to tear gas, ”he said.

As far as the effects of childbirth are concerned, the effects of the lower basin are unknown, but “this is a call for our scientific community to turn a blind eye to this issue,” he said.

Dr. Torgrimson: Ojerio also wondered if people had experienced other problems for more than a few hours after exposure to tear gas. She found that 80 percent of the survey participants were breathing problems, one of the most common complaints.

Kira Taylor, professor of epidemiology and public health at the Louisville School of Public Health and Information Sciences Conducting a similar studyDr. Torgrimson: Ojerio’s study provides “strong first evidence” that tear gas may be associated with menstrual irregularities. He added: “For many people, exposure to tear gas is the first study to document the long-term effects.”

Sven Erik Jordt, professor of anesthesiology, pharmacology, and cancer biology at Duke University School of Medicine, praised the work.

The majority of studies conducted by police agencies and the government on the safety of tear gas are “outdated, often between the ages of 50 and 70, and do not fit modern toxic practices,” he said. Most of these studies were conducted by healthy young men at the time, both by the police and the military, and not by women or general civilians representing the opposition.

Dr. Torgrimson: Ojerio and colleagues in July recruited surveyors on social media and links to the Oregon and Oregon Health Authority websites in July and August.

The researchers asked the participants to explain exactly how the menstrual cycle was affected after exposure to tear gas. Abdominal cramps, abnormal droplets, and severe or prolonged bleeding were the most common responses. Many people do not menstruate as a result of hormone therapy or often Age Unexpected bleeding and seizures, said Dr. Torgrimson-Ojerio.

This study has limitations. It is not a random sample.

“People who feel they have been harmed by tear gas may be more likely to respond than those who are exposed,” said Dr. Taylor. This means that certain numbers may be exaggerated. ”

Researchers were unable to verify their accounts because subjects were allowed to participate anonymously.

Also, the study did not answer how or why tear gas contributes to menstrual irregularities or how many other factors are involved. The authors point out that the high level of anxiety and stress among opponents may also have contributed to the physical response.

“Illness, anxiety, dehydration and physical exertion can all play a role,” says Dr. George. Alternatively, tear gas can act as an endocrine disrupter by interfering with normal hormonal function.

“Sometimes the CS gas-releasing agent is a chlorine-based chemical compound that produces additional chlorine when burned in the cans used by the police,” he said. Exposure to chlorine-containing chemicals affects menstrual health. ”

Alexander Samuel, a molecular biologist in France He has been investigating Same questions Since French protesters began reporting menstrual irregularities.

He mentioned two more areas for testing: a tear gas is converted into cyanide, which can cause heavy bleeding during menstruation, and a shock may play a role in altering menstrual cycles.

During the Arab Spring protests, the suspicion of tear gas and menstruation first arose ten years ago, Dr. Jord said.

Linn In 2011, Chile did the same Blocked The use of tear gas after a study can cause CS gas miscarriage and harm to young children. Three days later, the Chilean police He lifted the ban, Stating that the type of tear gas used is perfectly safe.
