Is it normal to have blood clots during menstruation?
In general, the presence of blood clots during menstruation is usually normal. Here's a detailed explanation:
Menstrual fluid consists not only of blood but also endometrial tissue fragments, cervical mucus, and shed vaginal epithelial cells. Due to the action of plasmin, menstrual blood typically does not clot. However, when menstrual flow is heavy or drainage is obstructed, blood may accumulate in the uterine cavity or vagina and coagulate into clots. These clots are usually small, with a diameter no more than 1 cm, and vary throughout the menstrual cycle.
If the blood clots are unusually large or accompanied by symptoms such as menorrhagia (excessively heavy bleeding) or severe dysmenorrhea (painful periods), further medical evaluation may be necessary. This could indicate underlying conditions such as adenomyosis, uterine fibroids, dysfunctional uterine bleeding, or endometrial polyps. Doctors will assess the regularity, duration, and volume of menstruation to determine whether the menstrual cycle is normal.
In daily life, it is recommended to maintain healthy lifestyle habits, practice good personal hygiene, and avoid excessive fatigue and emotional stress, all of which contribute to maintaining reproductive health.
