Smoking elevates stroke risk, especially in women.
Scientists have uncovered yet more evidence that quitting smoking is essential to protecting the brain. A large study comparing the risk of lethal stroke among men who smoke with the risk for women who smoke found that women in Western countries are significantly more likely to die of a hemorrhagic (or bleeding) stroke than their male counterparts. Smokers of both sexes face a more than 50 percent increased risk of ischemic stroke (caused by a clot that blocks blood flow to the brain) compared to individuals who do not smoke, according to the research, which was published online Aug. 22, 2013 in the journal Stroke. An analysis of data from 81 studies involving 3,980,359 individuals revealed a 17 percent higher risk for bleeding stroke among female smokers versus male smokers. The researchers theorized that the elevated risk may result from differences in hormones and in the way nicotine affects blood fats. Female smokers are known to experience greater increases in fats, triglycerides, and cholesterol than male smokers.
