Postpartum depression (PPD) is a clinical mood disorder that affects approximately one in seven new mothers. Unlike the baby blues, postpartum depression does not resolve on its own within a couple of weeks. It is more intense, more persistent, and significantly more disruptive to daily functioning.
PPD can develop any time within the first year after childbirth, though it most commonly appears within the first few weeks to months. It can begin suddenly or gradually, and many women initially mistake it for an extended case of the baby blues – which is one reason it so frequently goes unrecognized and untreated.
The symptoms of postpartum depression go beyond ordinary new-parent exhaustion. They include persistent sadness or emptiness, loss of interest in the baby or in activities that previously brought pleasure, feelings of worthlessness or guilt, difficulty bonding with the newborn, severe anxiety, changes in appetite or sleep that go beyond typical new-parent disruption, difficulty concentrating, and in more severe cases, thoughts of harming oneself or the baby.
