PCOS can negatively impact mental health due to various factors such as stress from PCOS symptoms, genetic predisposition, chronic inflammation, abnormal hormone levels like anovulation and low progesterone, insulin resistance, and some birth control pills. Adopting an anti-inflammatory diet through weight loss, reducing sugar intake, and time-restricted eating as well as addressing insulin resistance by lowering carbohydrates, avoiding snacking, getting enough sleep, and reducing sitting can help improve mental health issues related to PCOS.
