It has been found that the risk of suffering a stroke from estrogen-only hormone replacement therapy (HRT) gradually fades with time once the treatment is stopped. This study comes as good news for women in their postmenopausal age as these women are more likely to resort to hormone therapy for treating menopausal symptoms like hot flashes.

However researchers at the Washington University School of Medicine have warned that taking this hormone therapy up to 6-years is alright but if extended beyond that then it will always be risky. Earlier studies had linked hormonal therapy with increased risk of stroke, blood clots and fewer hip fractures. But this latest study has reported that the risk of stroke, blood clots, heart diseases and breast cancer comes back to normal once the treatment is stopped. However these results are applicable only for elderly women in their 50's who have undergone hysterectomy.

The study has been published in the Journal of the American Medical Association.
