If a girl good points extreme weight throughout being pregnant or develops pre-eclampsia or gestational diabetes, that may additionally enhance her threat of clots and stroke later in life.
Black ladies in the US usually tend to have a stroke than some other group of girls. Additionally they usually tend to have strokes at youthful ages and to have extra extreme strokes. Many components could drive this elevated threat, together with a lifetime of racial discrimination; poorer entry to well being care to handle underlying circumstances; and a better normal incidence of hypertension, elevated ldl cholesterol and weight problems, in addition to genetic circumstances like sickle cell anemia .
