Postpartum mood disorders include postpartum depression, postpartum bipolar episodes, and postpartum psychosis, which is usually an affective disorder. Postpartum anxiety must also be considered, as it is extremely common for postpartum women to experience anxiety, and they are at particularly high risk of obsessive symptoms. In this session, Dr. Freeman will discuss presentation and risk factors for these disorders, treatment considerations, and breastfeeding and sleep considerations.
