Polycystic Ovarian Syndrome (PCOS) is a hormonal disorder that affects the pituitary gland and triggers a hormonal imbalance. This causes ovaries to become enlarged, with small cysts on the outer edges. Although the cause of polycystic ovary syndrome isn't well understood, it may involve a combination of genetic and environmental factors. There have been studies on the links between thyroid issues and PTSD with PCOS. Some cases of PCOS are more severe than others. Lifestyle changes, such as diet and regular changes, can help reduce your symptoms.
