What causes blood clots in the uterus?

Blood clots in the uterus may be related to factors such as menorrhagia, endometriosis, uterine fibroids, miscarriage, and coagulation disorders. A small amount of blood clots during menstruation is mostly normal. If it is accompanied by abdominal pain, heavy bleeding, or long-lasting bleeding, you need to be alert to pathological causes.

1. Excessive menstrual flow

When the endometrium is shed during menstruation, if the bleeding volume is large or the flow rate is fast, the blood may coagulate in the uterine cavity to form dark red blood clots. This situation is usually related to hormone fluctuations and mental stress. You can try hot compresses on the abdomen to relieve discomfort. If necessary, use tranexamic acid tablets, Yunnan Baiyao capsules and other hemostatic drugs as directed by your doctor.

2. Endometriosis

Ectopic growth of endometrial tissue may lead to poor discharge of menstrual blood and the formation of chocolate-like blood clots, which are often accompanied by severe dysmenorrhea. The disease is related to immune abnormalities, reflux of menstrual blood and other factors. After diagnosis, it may be necessary to use dienogest tablets, ibuprofen sustained-release capsules and other drugs, or undergo laparoscopic surgery.

3. Uterine fibroids

Submucosal fibroids may deform the uterine cavity, affect the discharge of menstrual blood and form blood clots, which are often accompanied by symptoms such as prolonged menstruation and anemia. The growth of fibroids is related to excessive estrogen levels. Smaller fibroids can be observed, but larger fibroids require consideration of drug treatment such as mifepristone tablets or myomectomy.

4. Miscarriage

In spontaneous abortion or incomplete abortion, the mixture of pregnancy tissue and blood in the uterine cavity may excrete larger blood clots, which are often accompanied by lower abdominal pain. Ultrasound examination is required to confirm the condition of the uterine cavity. Incomplete abortion may require motherwort granules combined with oxytocin injection to promote the discharge of residues.

5. Coagulation dysfunction

Diseases such as thrombocytopenia and hemophilia can cause abnormal coagulation, making menstrual blood difficult to coagulate and forming a large number of blood clots. Such patients may have gum bleeding and subcutaneous ecchymosis at the same time, and need to be treated with tranexamic acid injection or coagulation factor infusion after hematology examination.

Daily attention should be paid to recording the menstrual cycle, blood clot size and accompanying symptoms, and avoiding strenuous exercise during menstruation. It is recommended to conduct gynecological ultrasound and hormone level examination every year. If the diameter of the blood clot exceeds 3 cm or the menstrual cycle is abnormal for 3 consecutive years, you should seek medical treatment in time. You can drink an appropriate amount of brown sugar ginger tea during menstruation to warm the uterus, but avoid eating raw or cold foods to aggravate blood stasis.
