Causes of Blood Clots in Period
- Enlarged Uterus: This cause of menstrual blood clots applies to new moms only. A woman's uterus expands itself to accommodate the growing fetus. After childbirth the uterus shrinks to its normal size, just as it had expanded. However sometimes it does not shrink, which is why blood pools inside and then passes when you have a period. Now there might be gap between the time it gets collected in the uterus to the time it is passed out, which is why blood clots form.
- Miscarriage: Miscarriage and blood clots are closely related. The history of miscarriage can be a reason of blood clots during period. If one is passing blood clots and there is a possibility of pregnancy, one should immediately contact the gynecologist as there might be a possibility of miscarriage. As stated earlier, blood clots in period after miscarriage are common, so one should consult a gynecologist during the next pregnancy.
- Endometriosis: Endometriosis is a medical condition which causes hormonal changes, which lead to menstrual blood clots. What happens in this condition is that a tissue, which is supposed to grow on the lining of the uterus, grows at some other place instead. If endometriosis is the cause of blood clots, one needs to take proper treatment from an experienced gynecologist.
- Leiomyoma: Leiomyomata, also known as uterine fibroid are non-cancerous tumors that are formed in the womb. One of the symptom of leiomyomata can be blood clots. If the fibroid are small, there might be no symptoms at all.
- Blockage: If due to some reason the menstrual blood gets obstructed, one might notice blood clots in period. Menopause or benign polyps can be two reasons behind this. Benign polyps change the flow of blood during menstruation, which is why clots might form. And during menopause, the cervical canal might become smaller due to lowered estrogen levels which leads to menstruation blood clots.
- Medication: Certain medications like steroids or anti coagulants can also cause blood clots during menstruation. Oral contraceptive pills can also cause blood clots during period as they bring about a change in the normal hormonal balance of the body.
