What causes blood clots during menstruation?

The presence of blood clots during menstruation may be caused by the following factors: 1. Normal condition: Under normal circumstances, menstrual blood does not coagulate due to the action of plasmin. However, when shed endometrial tissue adheres to blood and is expelled together, blood clots may form. This is considered normal and requires no special treatment. 2. Heavy menstrual flow: Some women may experience increased menstrual bleeding due to consuming large amounts of blood-nourishing foods or engaging in intense physical activity during their period. The mixture of menstrual blood and shed endometrium may result in blood clots. 3. Hormonal imbalance: Factors such as staying up late or irregular eating habits may lead to endocrine disorders. Hormonal changes in the body can cause heavier menstrual bleeding, resulting in the passage of blood clots. 4. Gynecological diseases: Conditions such as endometritis or endometrial polyps may cause increased menstrual bleeding, leading to the formation of blood clots. If there are large amounts of blood clots during menstruation or if they are accompanied by discomfort such as abdominal pain, it is recommended to seek timely medical attention at a gynecology clinic.
