Dark Clotted Menstrual Blood: Be Aware of These 5 Serious Causes

Menstruation is a natural part of the female reproductive cycle. Typically, menstrual blood is bright red or dark red. However, there are instances where you may notice “dark clotted menstrual blood.” While this can be a normal occurrence, it can also indicate underlying health issues.

Causes of Dark Clotted Menstrual Blood

  1. Old Menstrual Blood: If menstrual blood takes longer to exit the body, it gets exposed to oxygen, turning dark brown or black. This often occurs at the end of the menstrual cycle.
  2. Hormonal Imbalance: An imbalance in hormones such as estrogen and progesterone can slow the shedding of the uterine lining, causing blood to stagnate and darken.
  3. Stress and Anxiety: Prolonged stress can affect the menstrual cycle, leading to irregular periods and changes in menstrual blood color.
