Perinatal depression, affecting roughly 18.4% of women with depressive symptoms and 12.7% diagnosed with major depressive disorder, is a significant mental health concern. Common symptoms include sadness, anxiety, guilt, mood swings, excessive worry about the baby, hallucinations, and harmful thoughts towards self or baby. Depending on symptom severity, professional help and lifestyle adjustments may be recommended.

Perinatal anxiety disorders, encompassing generalized anxiety, obsessive-compulsive disorder, panic disorder, and social anxiety, vary in prevalence: 6.1-7.7% of women experience generalized anxiety, 1.2-5.2% obsessive-compulsive disorder, 1.4-9.1% panic disorders, and 0.2-6.5% social anxiety. Importantly, 66% of women with perinatal depressive disorders also develop a perinatal anxiety disorder. Women with a history of anxiety disorders are more prone to their intensification during the perinatal period.

Postpartum psychosis, affecting two in every 1,000 births, can manifest as mood shifts, confusion, bizarre behavior, insomnia, and hallucinations soon after birth. Women with a history of bipolar disorder have a 23.3% risk of needing psychiatric care within the first month postpartum, with factors like genetics, hormonal changes, sleep deprivation, and mood changes playing a role.
