This video traces the link, not necessarily evident, that exists between asthma attacks and bad weather. In fact, American scientists show that a few days before a thunderstorm, more people go to the emergency room for a respiratory problem.

Pollen, respiratory allergy, activity physicist or air pollution are known triggers asthma attacksbut there would be another much less studied by scientists: hormone female sexuality. A report from the English Association Asthma + Lung United Kingdom indicates that women between the ages of 29 and 40 are 2.5 times more likely to be hospitalized following a strokeasthma Only men.

Asthma affects more women in adulthood

In childhood, boys are more likely to do this asthmabut the puberty reverse the balance. In adolescence and adulthood, women with asthma outnumber men. The phenomenon is very clear by observing theimpact adult asthma by gender: 5.9 cases per 1,000 person-years in women versus 4.4 cases per 1,000 person-years in men the latest study on the subject dating back to 2005. Some asthma experts believe that female sex hormones are involved in asthma attacks and their severity in women. Although many studies have been conducted on the subject, the results remain partial and the underlying mechanisms poorly understood. Socio-economic factors, environmental or biologics other than hormones may also be involved.

Patients with asthma see differences in the severity of their symptoms depending on the time period. Poppy Hadkinson, a 30-year-old English woman, testifies for the association Asthma + Lung United Kingdom : ” There seemed to be a pattern in my symptoms, related to my menstrual cycle. Almost every month before my rules, I suffered from asthma. My symptoms made it difficult to breathe, which was terrifying, and I often ended up in the hospital. The asthma attacks I suffered were so severe that I was ventilated four times when I was 22 and wondered if I would make it until my next birthday. “.

Hormone-related asthma

The testimonies have no scientific value, but they suggest the existence of a phenomenon that science has not yet understood. According to a study published in 2022 in Asthma and allergy diary, Symptoms of asthma can vary throughout a woman’s life, from puberty to menopauseduring the menstrual cycle e the pregnancy. Hormone treatments also affect them. The pill seems to limit the appearance of new seizures, while the replacement hormones prescribed after the menopause favor them. Many associations, but no clear causal link.

More than two-thirds of asthma deaths were in women

By understanding the role of sex hormones in asthma, we could transform the lives of three million women with the disease in the UK and many millions more around the world. We urgently need to invest more in research in this area to be able to do so find new treatments and make better use of existing treatments to help millions of women and save lives “says Sarah Woolnough, President ofAsthma + Lung United Kingdom.

The question is all the more important since adult asthma differs greatly from childhood asthma. More severe and chronic, the prognosis of the disease is worse and the chances of remissions lower in adults. Most women show symptoms of adult asthma, but in some men, asthma remains infantile and therefore less severe. With a more complex etiology and more severe disease, women are more likely to die from asthma than men.

The figures ofAsthma + Lung United Kingdom indicate that more than two-thirds of asthma deaths were in women: 5,100 women compared to about 2,300 men. The association advises asthmatics, men and women, to follow the treatment according to the doctors’ instructions and to undergo a check-up every year to better prevent crises.
