Postpartum psychosis

Also called Puerperal psychosis

Postpartum psychosis is a serious mental illness that can develop after having a baby, usually within the first 2 weeks. Symptoms can include hallucinations, delusions, mania or severe confusion and can come on quickly. It is more likely in people with bipolar disorder or a family history of it.
