Passing of small clots during menstrual cycle is quite a common and natural phenomenon and nobody takes notice of them. Somehow, when women begin to pass unusually large size of clots with heavy bleeding, it often becomes a cause of concern and depression among women.
Typically, women pass large clots on the days when the menstrual bleeding is heavy. It happens so because your body typically produces anticoagulants to keep the clot from forming but when the menstrual flow is heavy and the blood is being quickly expelled the anticoagulants do not get time to work and hence clots keep coming out. If you experience excessive clots or clots are larger than the size of your fist, you must contact your gynecologist. Following are the primary causes of large clots.
Causes Of Large Clots During Menstruation
Fibroids are non cancerous growths in uterus which are responsible for large clots during periods. Fibroids do not cause symptoms always.
Researchers believe that most women with small fibroids do not get to know about the fibroids in their uterus but tend to bleed more and pass larger clots.
If you had one time passed a really big clot which is unusual otherwise than check with your doctor. It could be a miscarriage or pregnancy related complication. Though most of the times the clots caused by spontaneous abortion are released without menstrual bleeding but sometimes they are not released until the menstrual period begins, leading to confusion as to whether they were part of menstrual blood or pregnancy related complication.
The body of a woman relies on a delicate balance of sex hormones like estrogen and progesterone. These sex hormones are primarily responsible for regulating and shedding the menstrual blood.
When this intricate balance is disturbed, it can lead to formation and subsequent shedding of thick uterine lining including clots. Hormonal imbalance can be caused by drastic weight loss, menopause or side effects from some medication, etc.
Polyps are fibroid like growth structures in the uterus but instead of developing in uterus they develop in the cervix. They are red, finger shaped growths which cause hindrance in the passage of blood during menstrual periods causing clot formation.
These polys may change the flow of blood during periods and can in fact slow down the passage of blood during menopausal time because the cervix gets shrunk due to falling estrogen levels. This can increase the likelihood of large clot formation.
Endometriosis Or Adenomyosis
Endometriosis is that condition of body in which uterine tissue develops at wrong place and not in uterus. Generally, the uterine tissue is formed outside the uterus.
On the other hand, adenomyosis is that condition in which uterine lining develops in the muscles that make uterine walls. Both of these conditions can cause heavy bleeding and passage of large clots.
Larger Than Normal Uterus Size
If your uterus has not returned to normal size after delivery then chances are that the menstrual blood gets enough time to collect and coagulate before it is expelled from the body. This delay can also result in change of color of your menstrual blood and clots.
