What Causes Heavy Menstrual Bleeding with Large Blood Clots?

Under normal circumstances, menstrual blood is dark red and fluid. However, if you notice blood clots during your period, you should pay attention to them, as this often indicates an underlying issue. So, what causes excessive blood clots during menstruation?

What Causes Excessive Blood Clots During Menstruation?

Excessive blood clots during menstruation may result from factors such as shedding of the endometrium. When large amounts of endometrial tissue are shed, blood clots commonly form during menstruation. This occurs because menstruation is a vaginal bleeding phenomenon triggered by cyclical endometrial shedding, which itself is regulated by periodic fluctuations in ovarian hormones. Normally, menstrual blood contains only small fragments of endometrial tissue and desquamated vaginal epithelial cells; however, when substantial endometrial shedding occurs, it can lead to the formation of noticeable blood clots.

If you experience numerous blood clots during your period, first ensure warmth in the abdominal area. Avoid raw or cold foods, and instead consume warming, nourishing foods. Options include ginger–brown sugar water, Yimucao (Leonurus japonicus) granules, or Shaofu Zhu Yu granules, all of which help promote blood circulation, resolve stasis, and regulate menstruation. Additionally, prioritize rest and avoid staying up late, as fatigue may exacerbate menstrual bleeding. If bleeding progressively increases and is accompanied by abdominal pain, Baogong Zhixue granules may be considered to alleviate discomfort.

Maintain good personal hygiene during menstruation to prevent infection. We hope this information is helpful to you.
