According to the results, published by the researchers from the American Heart Association, smoking women are at much greater risk of brain bleeds, though smoking increases the chance of brain bleeds in both sexes.
A brain bleed, or a subarachnoid hemorrhage, happens in the result of bleeding into the area between the brain’s surface and the underlying tissue. It can result in seizures, coma, and ultimately death, according to the U.S National Library of Medicine.
Researchers have found that smoking women were more likely to develop brain bleeds than non-smokers, regardless of the number of cigarettes smoked. However, women, who smoked 21 – 30 cigarettes a day, were at the greatest risk. These women were more than 8 times likely to develop a bleed compared to non-smokers.
