Stroke, a medical emergency, occurs when blood flow to the brain is interrupted. This interruption can be due to either a blocked or ruptured blood vessel in the brain.
As per the World Stroke Organization, stroke is the leading cause of death and disability worldwide, with women accounting for almost two-thirds of related deaths. Moreover, female stroke survivors are often left with a greater degree of disability than males.
The Menstrual Cycle and Stroke Risk Factors
The menstrual cycle is an intricate and complex process, taking place in the female reproductive system every month. It is influenced by the release of hormones like estrogen and progesterone.
These hormones are secreted in a cyclic pattern, resulting in various changes in the female body.
Research has shown that stroke risk in women is influenced by the hormonal changes that occur during their menstrual cycle. These fluctuations impact the important stroke risk factors such as blood pressure, blood sugar, and cholesterol levels.
Timing of Menstrual Cycle and Stroke Risk
There are two main phases of the menstrual cycle: the follicular phase and the luteal phase. The follicular phase occurs during the first half of the menstrual cycle, while the luteal phase occurs during the second half.
Studies indicate that women who experience ischemic stroke are more likely to be in the luteal phase of their menstrual cycle when the stroke occurs.
This is because the luteal phase is associated with higher levels of hormones like estrogen and progesterone, leading to changes in blood pressure and clotting factors, which can increase stroke risk.
Oral Contraceptives and Stroke Risk
Many women use oral contraceptives to prevent unintended pregnancies. These hormonal medications can also impact stroke risk, especially in women who have preexisting risk factors for stroke.

Oral contraceptives can increase the risk of a blood clot forming in the brain, particularly in women who have a history of migraines with aura or blood clotting disorders.
It is important for women to discuss their individual risks with their doctors before starting oral contraceptives.
Pregnancy and Stroke Risk
Pregnancy is another time when women may experience hormonal changes that can impact their stroke risk. This is because pregnancy causes significant changes in blood pressure and blood volume.
Research shows that pregnant women with high blood pressure could be at a higher risk of developing a stroke.
Additionally, women who have had high blood pressure during pregnancy may have a greater risk of developing stroke in the years following their delivery.
Mitigating Stroke Risk in Women during their Menstrual Cycle
While there may be little women can do to prevent hormonal fluctuations that occur during their menstrual cycle, there are steps they can take to mitigate stroke risk:.
- Reduce high blood pressure: High blood pressure is a common risk factor for stroke. Women can reduce their blood pressure by following a healthy diet, exercising regularly and taking blood pressure medications, if prescribed by their doctor.
- Manage diabetes: Diabetes can increase the risk of stroke. Women can reduce their diabetes risk by eating a healthy diet, engaging in regular physical activity and taking their diabetic medication, if prescribed.
- Quit smoking: Smoking is a significant risk factor for stroke. Women should quit smoking and avoid exposure to secondhand smoke.
- Maintain a healthy weight: Being overweight or obese can increase the risk of stroke. Women can maintain a healthy weight by eating a healthy diet and engaging in regular physical activity.
- Control cholesterol levels: High cholesterol levels can contribute to stroke risk. Women can manage their cholesterol levels by eating a healthy diet and taking cholesterol-lowering medications, if prescribed by their doctor.
Conclusion
The menstrual cycle and hormonal fluctuations during the cycle can significantly impact a woman’s stroke risk. Women need to be vigilant in understanding their individual risk factors and take active steps to mitigate their stroke risk.
It is important for women to work with their doctors to manage their health, particularly if they have preexisting conditions that can increase their risk of stroke.
