What causes abnormal heavy bleeding between periods in individuals with PCOS?

Polycystic Ovary Syndrome (PCOS) can cause abnormal heavy bleeding between periods, mainly due to hormonal imbalances. These imbalances often result in the body producing too much estrogen without enough progesterone, which can lead to the thickening of the uterine lining. When the lining becomes too thick, it can shed irregularly and unpredictably, resulting in heavy bleeding.

Causes of Heavy Bleeding in PCOS:

1. Hormonal Imbalance: In PCOS, the body may not produce enough progesterone, leading to an imbalance of progesterone and estrgoen. This can cause the uterine lining to grow too much and shed irregularly.
2. Irregular Ovulation: Many individuals with PCOS do not ovulate regularly, which means that the lining of the uterus doesn't shed regularly, leading to heavy bleeding when it does.

Understanding these causes can help in managing and treating abnormal bleeding. Treatments often focus on regulating hormones, which may involve lifestyle changes, medication, or other therapies. Always consult a healthcare provider for personalized advice and treatment options.
