An alarming one in three U.S. adults have at least one condition that spikes their stroke risk, such as high blood pressure, high cholesterol, obesity, and diabetes, the CDC says. But new research shows that women with another common condition are at a 34 percent increased risk of stroke. Read on to learn whether you or a loved one may be at a higher risk of experiencing a potentially life-threatening medical emergency—and what you can do to help prevent it.

Ischemic stroke is more common, and is caused by artery blockage that severely reduces blood flow to the brain. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing the brain to bleed. In either case, seeking immediate medical attention is critical in order to reduce brain damage. Knowing the symptoms enables you to take swift action and potentially save a life. The signs and symptoms of a stroke are sudden and appear without warning, says the CDC. These include numbness in the face, arms, or legs (especially one side of the body), confusion, difficulty speaking, vision problems, dizziness, loss of balance, and severe headache. If you experience any of these symptoms or notice them in someone else, call 911 immediately. READ THIS NEXT: Drinking a Cup of This a Day Can Slash Your Stroke Risk, New Study Says. A new study published in the American Heart Association (AHA) journal Stroke examines the link between stroke and endometriosis—a chronic condition in which tissue similar to the tissue that lines the uterus walls (the endometrium) grows outside the uterus. Endometriosis affects approximately 10 percent of reproductive-aged women in the U.S., according to the study’s authors. Researchers analyzed data from more than 110,000 women over a period of 28 years and concluded that those with endometriosis had a 34 percent increased stroke risk compared with those who didn’t have the common condition. They saw no significant differences between endometriosis and stroke risk across other factors, such as age, infertility, body mass index, or menopausal status. “These findings suggest that women with a history of endometriosis may be at higher risk of stroke,” Stacey Missmer, ScD, study senior author and a professor of obstetrics, gynecology, and reproductive biology at Michigan State University College of Human Medicine, said in a statement. “Clinicians should look at the health of the whole woman, including elevated blood pressure, high cholesterol, and other new stroke risk factors, not only symptoms specifically associated with endometriosis, such as pelvic pain or infertility.” According to the study, previous research found that women with endometriosis are also at greater risk of cardiovascular diseases, such as heart attack, high blood pressure, and high cholesterol. However, the exact mechanism through which endometriosis is associated with cardiovascular disease remains unclear.ae0fcc31ae342fd3a1346ebb1f342fcb “We hypothesize that inflammation may contribute to part of the association between endometriosis and risk of stroke,” explains Leslie Farland, ScD, study author and assistant professor of epidemiology and biostatistics at the University of Arizona. “Additionally, we observed that gynecologic surgery, such as hysterectomy and oophorectomy, may also contribute to the risk.” For more health news sent directly to your inbox, sign up for our daily newsletter. While there’s no universal treatment for endometriosis, it’s advised that all women eat a healthy, nutritionally balanced diet and exercise regularly to stave off this painful condition and lessen their stroke risk. The AHA recommends getting at least 150 minutes of moderate-intensity or 75 minutes of vigorous aerobic activity per week. “Physical activity can help improve endometriosis pain symptoms, as well as improve other risk factors associated with cardiovascular disease,” explains Farland. “Women and their health care providers should be aware of endometriosis history, maximize primary cardiovascular prevention, and discuss signs and symptoms of cardiovascular disease.” Maintaining a healthy body weight, avoiding alcohol, limiting caffeine intake, and having routine medical exams to check blood pressure and cholesterol levels can all help reduce your chances of developing endometriosis, according to the U.S. Department of Human and Health Services.
