What could cause an abnormal heavy period with clots in someone with PCOS?
In someone with PCOS, heavy periods with clots can be caused by hormonal imbalances affecting the lining of the uterus, leading to irregular shedding and bleeding.
Explanation
Polycystic Ovary Syndrome (PCOS) can lead to heavy periods with clots due to hormonal imbalances. These imbalances affect the endometrium, which is the lining of the uterus.
Causes of Heavy Bleeding
- Hormonal Imbalance: PCOS often leads to irregular hormone levels, disrupting the normal menstrual cycle and causing the uterine lining to build up excessively. When it sheds, it results in heavy bleeding.
- Endometrial Dysfunction: According to medical literature, issues with how the endometrium functions can also contribute to abnormal bleeding patterns.
- Ovulatory Dysfunction: PCOS often leads to irregular ovulation or lack of ovulation, which can cause the uterine lining to become too thick.
In summary, the combination of hormonal imbalances and endometrial dysfunction in PCOS can lead to heavy periods with clots. If someone experiences these symptoms, it's important to consult a healthcare provider for proper diagnosis and management.
