Why Do Some Women Experience Low Blood Pressure During Their Periods? Expert Explains

Many women experience low blood pressure during their menstrual cycle due to several physiological and hormonal changes. Heavy menstrual bleeding can lead to significant blood loss, which reduces the volume of circulating blood and can cause symptoms such as dizziness, fatigue, and weakness. This loss of blood, compounded by deficiencies in iron and fluids, can result in low blood pressure during periods.

Hormonal fluctuations, particularly in estrogen and progesterone levels, directly affect blood vessels and circulation. These hormonal changes can cause blood vessels to dilate, lowering blood pressure and sometimes leading to symptoms like lightheadedness or fainting. Additionally, dehydration due to fluid loss during menstruation further decreases blood volume, exacerbating low blood pressure.

Pain during menstruation, especially severe menstrual cramps, can trigger vasovagal responses that cause sudden drops in blood pressure, leading to fainting episodes. Overuse of painkillers to manage cramps can also contribute to lowering blood pressure.

Women more susceptible to low BP during periods include those with anemia from heavy bleeding, those prone to dehydration, or those who are underweight or have weaker physical health. Preventative measures include staying well-hydrated with fluids like water, coconut water, and lemon water, consuming iron and vitamin C-rich foods to combat anemia, managing pain through safe methods, and ensuring adequate rest and stress reduction.

If symptoms such as frequent dizziness or extreme fatigue persist, it's advisable to seek medical advice to rule out underlying health issues and receive appropriate treatment. Maintaining a balanced diet and proper hydration can help most women navigate menstrual low blood pressure more comfortably.
