The emotional and psychological well-being of women is deeply influenced by life stages such as menstruation, pregnancy, postpartum recovery, and menopause. Each phase involves significant biological and social changes that may increase vulnerability to mental health conditions. Women’s mental health and perinatal psychiatry now focuses on identifying and treating mood and anxiety disorders that emerge or intensify during these reproductive phases. Postpartum depression, perinatal OCD, and anxiety disorders can have lasting effects on both mother and infant if not addressed early. Current strategies involve a multidisciplinary model combining psychiatry, obstetrics, and social support systems. Treatment approaches carefully weigh the safety of pharmacologic interventions during pregnancy and breastfeeding. Early screening, hormonal research, and culturally sensitive care models are expanding access and improving outcomes for women across diverse populations.
