What causes low mood after birth?

After delivery, oestrogen and progesterone change quickly. Feeding demands, night waking, discomfort, anaemia, and adjusting to a new role can make emotions harder to manage. A short spell of tearfulness or irritability may settle with rest and practical help, but persistent or worsening symptoms need attention.

Postnatal depression commonly presents with low mood, loss of enjoyment, guilt, poor concentration, or difficulty feeling connected to the baby. Postpartum anxiety presents with excessive worry, dread, panic, or distressing thoughts. Thyroid inflammation after pregnancy can also affect energy and mood. These conditions are treatable and are not a sign of poor parenting.

Tell someone you trust how you are feeling and accept help with meals, errands, feeds, or rest. Arrange a review with a midwife, obstetrician, family doctor, or mental health professional if symptoms continue, interfere with daily care, or feel difficult to explain. A clinician may ask about sleep, bleeding, pain, medicines, thyroid symptoms, and thoughts of self-harm before discussing support options.

Seek urgent help now if you may harm yourself or the baby, feel unable to stay safe, hear or see things others do not, or feel unusually confused, agitated, or detached from reality. Contact emergency services or go to an emergency department. If low mood is worsening without immediate danger, request prompt clinical support.
