The amount of menstruation is very variable between people. In addition, the same person may have different rules during his life. Normally, between 25 and 80 ml are bled, and it is considered excessive when this amount is greater than 80 ml per day.
When there is a large amount of bleeding, it can accumulate and organize in the form of a clot (semi-solid mass), but it is not the fact that it is in clots but rather the excess amount that leads us to have to study the case.
There are different causes of heavy bleeding and these should be evaluated by a gynecologist. Not all heavy bleeding has a known cause or negative impact.
The gynecologist may order tests to rule out different causes of heavy bleeding:
- Endometrial polyps.
- Fibroids.
- Adenomyosis (endometriosis affecting the uterine cavity).
- Carrying a copper IUD.
- Taking some drugs such as antiaggregants or anticoagulants.
- Thyroid, cortisol or coagulation disorders.
- Hormonal changes: especially during adolescence and premenopause.
- Genetic inheritance.
- Abortion (in this case, the bleeding would be occasional and usually does not coincide with the expected date of the rule).
If it is ruled out that there is a cause that could also affect fertility, you can have abundant periods, with clots, without these indicating a problem. Of course, it must be controlled that it does not lead to anemia and, if so, treat it.
