Research publshed in the journal Thorax tracked 57,000 French women of menopausal age and evaluated their medications. They found that women who took oestrogen-only HRT were 67% more likely to develop asthma.

Of the 57 or so women who were diagnosed with asthma each year during the study, 56% of them had taken HRT within the past two years. Participants who had previously had an allergic disease and who also took HRT had an increased risk of developing asthma as well. Researchers also saw a decreased risk of getting asthma in women who stopped taking HRT drugs for a few years.
