The duration of symptoms for postpartum depression can vary from person to person, as each individual experiences different levels of symptoms. Postpartum depression most often occurs within six weeks after childbirth, and generally, symptoms may alleviate on their own within three to six months after giving birth. The onset of postpartum depression is primarily a stress response caused by physiological and psychological factors. With careful attention from family members and proper treatment, recovery is usually swift. However, in severe cases, recovery could take up to six months or even a year, and there is a possibility of relapse during subsequent pregnancies.
