Scientists have named the blood groups that have an increased risk of stroke in women

A blood type other than I may increase the risk of stroke in women who smoke and take oral contraceptives. Such data were obtained as part of a previous study.

Oral contraceptives may increase the risk of stroke in some women, especially smokers. Because of this, patients over 35 years of age who smoke are not recommended to take these drugs. Previous studies have shown that blood types II through IV may also increase the risk of stroke.

Using information from another study, the researchers compared the risk of stroke among women who smoked and used oral contraceptives, alongside a second analysis of women who only smoked or took contraceptives.

347 women who had a stroke under the age of 50 were included in the study. The control group without a stroke was 383 people.

Scientists found that women who smoked and took oral contraceptives were almost five times more likely to have a stroke than women who did not take drugs and did not have a bad habit. Blood group other than I further increased the risk of early stroke in women who smoked and took oral contraceptives. It was about increasing the risk by almost two times.
