Postpartum psychosis is a severe psychiatric disorder that occurs in some women following childbirth, characterized by symptoms like hallucinations, delusions, mood disturbances, insomnia, and feelings of anxiety. It develops abruptly within the first few weeks after delivery in less than 2 in 1000 deliveries. The cause is unknown but risk factors include genetic predisposition, hormonal changes after birth, personal or family history of mental illness, substance abuse and lack of social support. Rapid hospitalization is needed if the safety of the baby or mother is at risk. Treatment involves medication, counseling and family education. Breastfeeding is contraindicated during treatment due to potential effects of medications in breastmilk.
