The length of time someone has postpartum depression (PPD) depends on a few different factors. Typically, the symptoms of PPD appear within the first few weeks after giving birth, but sometimes PPD symptoms can appear up to a year after giving birth, so don't ignore your symptoms if they don't fall within the typical postpartum period. No matter when your symptoms start, they are valid and real and should be brought to the attention of a medical professional.
While there's no set length for how long postpartum depression lasts, some research suggests that symptoms will start to improve within three to six months after they first appear. However, symptoms can persist long after that period, and every woman is different. Seeking treatment is the best way to find relief from PPD symptoms.
