Hormonal

Postmenopausal hormone therapy (HT) is associated with a lower risk of subarachnoid hemorrhage (SAH) in women, contradicting assumptions that hormone replacement universally increases stroke risk.

If you are considering or using hormone therapy, discuss your specific stroke risks, particularly for hemorrhagic stroke, with your healthcare provider, as some data suggests it may lower SAH risk.

LimitedQualifiesMEDIUM confidence
A population-based case-control study showed that the risk of SAH was lower in women with first pregnancy after 23 years of age and in those who had ever used hormone therapy (HT).
