HRT raises asthma menace post menopause

A new study has discovered that oestrogen-only hormone substitution therapy (HRT) may put menopausal women at increased asthma risk. Compared with women who had never used any form of HRT, those who did use it were 21pct more likely to develop asthma.

Almost one in 10 women with a natural menopause (9.4pct), and more than one in four (28pct) of those with a surgically induced menopause, used HRT containing oestrogen alone.

The risk of asthma was momentous only among those using oestrogen alone.

Among these women the overall risk of asthma was 54pct higher than between those who had never used any form of HRT.

Oestrogen only users who had never smoked and those who had had some form of allergy before their asthma judgment were at greatest risk of developing asthma- 80pct and 86pct higher, correspondingly.

A small increased risk for asthma was also seen in women using combined oestrogen and progesterone HRT who were either non-smokers or who had had some form of allergic reaction in the long-ago.

They researchers said that while their result point to an increased risk of asthma, this must be judged in "the light of all the other health effects of HRT use, including its beneficial effect on the excellence of life of menopausal women."

The study appears in journal Thorax .
