Postpartum depression is curable. It is fundamentally a manifestation of reduced volitional activity, and most patients can be cured after a period of time. However, in everyday life, family support is needed, especially the psychological support from family members and husbands, which is very important. Postpartum depression is generally a self-limiting disease, but there are certain conditions for recovery. Patients with milder symptoms and shorter durations of illness generally have a better prognosis. Typically, it occurs within one month after childbirth, with symptoms becoming prominent within six months, and gradually diminishing after three to six months. However, one should not rely solely on self-healing and should actively seek treatment from professional medical practitioners.
