The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period. These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding. Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop.[1] Postpartum physiological changes may be different for women delivering by cesarean section.[2] Other postpartum changes, may indicate developing complications such as, postpartum bleeding, engorged breasts, postpartum infections.
