Increased Risk of Stroke Due to Endometriosis

A stroke results from a brain’s blood circulation disruption, typically stemming from a vascular blockage or a ruptured vessel within brain tissue [1]. This interruption deprives specific brain regions of the oxygen and nutrients they require, potentially leading to tissue death within a few hours [2].

A recent study in the United States has garnered significant attention [3]. This study has unveiled a connection between women diagnosed with endometriosis and a heightened susceptibility to strokes. This article aims to provide comprehensive insights into the study’s findings, guidance on recognizing stroke symptoms, and preventive measures you can take. Explore the details below.

What Does the Study Reveal?

In this United States-based study, epidemiologists explored the connection between endometriosis and the risk of stroke. The research drew upon data from the Nurses’ Health Study II (NHSII), a cohort study spanning nearly 28 years. Within this period, participants, aged 25 to 42 years, were meticulously screened for stroke occurrences from 1989 to 2017, with adjustments made for potential confounding factors.

The study uncovered a significant finding: among approximately 2,800,000 person-years of observation, 893 stroke cases were documented. Notably, women with laparoscopically confirmed endometriosis exhibited a 34% higher risk of stroke than their counterparts without endometriosis. This association was predominantly influenced by hysterectomy/oophorectomy, postmenopausal hormone therapy, and early menopause (before age 45). Conversely, no significant disparities emerged in the relationship between endometriosis and stroke concerning age, infertility, body mass index, or menopausal status.

It is important to note that the study did not provide information on specific stroke subtypes.

The increased stroke risk observed in women with endometriosis may be attributed to an elevated hyperinflammatory state characterized by heightened levels of inflammation in the bloodstream. Additionally, the study found a correlation between endometriosis and a higher likelihood of a family history of myocardial infarction or stroke [3], [4].

Good to Know!

Possible confounding variables considered in the analysis encompassed a range of factors, including alcohol consumption, body mass index during adolescence, current body mass index, age at onset of menstruation, menstrual patterns during youth, present menstrual characteristics, parity (number of pregnancies carried to term), historical use of oral contraceptives, previous smoking habits, dietary quality, physical activity level, utilization of NSAIDs (non-steroidal anti-inflammatory drugs), aspirin intake, racial or ethnic background, and participant income.

How to Identify Signs of a Stroke?

A stroke may manifest with symptoms like dizziness, paralysis, and difficulties in speech and vision. However, it is crucial to recognize that these signs can vary between genders, with women often displaying symptoms not typically associated directly with strokes [5]. These atypical symptoms can include shortness of breath, difficulty swallowing, hiccups, chest pain, headache, nausea, and confusion. It is important not to dismiss the possibility of a stroke when several of these indicators co-occur [6].

When stroke symptoms become apparent, swift action is paramount. Seeking immediate medical attention is crucial.

To aid in recognizing a stroke, especially in women, you can remember the acronym F.A.S.T.:

F = Face: Is one side of the face drooping when smiling?

A = Arms: Does one arm drift downward when both arms are raised?

S = Speech: Is speech slurred or unusual when repeating a simple sentence?

T = Time: If you observe any of these signs, do not delay; call for an ambulance right away [7]!

What Are the Risk Factors?

In general, stroke affects women more frequently than men, underscoring the importance of recognizing gender-specific strategies for prevention and treatment [5]. Research indicates that postmenopausal women, particularly those over 65, face an elevated risk of stroke [7]. Beyond experiencing higher mortality rates than men, women are more prone to disability, depression, and dementia following a stroke. Pregnancy, the postpartum period, and increasing age are notable pathophysiological aspects contributing to stroke risk in women [7].

While many risk factors are common to both men and women, there are also gender-specific factors that can heighten the risk, including:

  • High blood pressure (especially during pregnancy)
  • Hormone-related factors (such as birth control pills or hormone replacement therapy during menopause)
  • Pregnancy
  • Elevated body weight or obesity
  • Hypertension
  • Diabetes mellitus
  • Atrial fibrillation
  • Smoking and alcohol consumption
  • Elevated blood cholesterol levels
  • A family history of stroke or heart attack [2].

How Can I Take Preventive Measures?

NHSII recommends prioritizing primary cardiovascular prevention and discussing cardiovascular disease symptoms openly with healthcare professionals [3]. Additionally, you can incorporate preventive actions into your daily routine to lower the long-term risk of stroke. These measures include:

  • Maintaining a diverse and healthy diet.
  • Establishing a routine of regular exercise (or staying as active as possible and minimizing sedentary time).
  • Limiting or ceasing alcohol consumption and smoking.
  • Considering medications that may help reduce the risk of experiencing another stroke [8].

Should every endometriosis sufferer worry now?

No – the risk of stroke is relatively low for most people and depends on quite a few different factors. So if a low risk increases, it still remains low.

You always have to look at all the risk factors. Still, it can make sense to get informed and know what other risk factors there are and when you should talk to your doctor about them!

In a Nutshell

The NHSII cohort study revealed a 34% higher risk of stroke among women with endometriosis. Nonetheless, the study highlights the limitations of current research in this area, including short follow-up periods, limited consideration of potential confounders, and reproductive health history.

It is important to recognize stroke symptoms and risk factors with a gender-specific approach and tailor prevention and treatment strategies accordingly for each gender.
