Why might someone with PCOS miss a period even if they are not pregnant?
People with PCOS might miss periods due to hormonal imbalances that affect the menstrual cycle.
Explanation
Polycystic ovary syndrome (PCOS) can cause missed periods because it affects hormone levels. Hormonal Imbalance: In PCOS, the body may produce higher levels of male hormones, which can interfere with the regular release of eggs from the ovaries. This can lead to irregular or missed periods. It's important to note that while pregnancy is a common reason for missed periods, there are several other reasons related to health conditions and environmental factors that can also lead to irregular cycles.
