The postpartum review does not necessarily have to be 42 days, but can also be a few days earlier or later, which is normal. Generally speaking, 42 days postpartum review is mainly because the uterus has completely recovered to normal by 42 days postpartum, during this period, it is mainly used to observe the recovery of the uterus, whether there is irregular vaginal bleeding, the healing of the incision and the secretion of breast milk, which is used to judge whether the woman’s body recovers normally after delivery. If a woman has not recovered well by 42 days after delivery, she should be given symptomatic treatment in time. If there is any pelvic floor relaxation, pelvic floor function assessment can be done and pelvic floor muscle rehabilitation training can be given, which will have a very good rehabilitation effect.
