The recovery of maternal abdomen after cesarean section requires a certain process, which cannot be generalized and has individual differences. There are many factors that affect abdominal contraction after cesarean section. Generally, women with sufficient qi and blood and strong constitution can gradually recover to normal level in about 1 month, while women with weak constitution and insufficient qi and blood have a relatively long recovery time, which may be 2-3 months, and a few women with weaker constitution have poor recovery and may take 6 months to recover to their original state. In addition, due to the low activity during the puerperium, the increase of calories in the diet, the accumulation of abdominal fat thickens and makes it easy to develop abdominal obesity, which can make abdominal retraction more difficult. It should be noted that most pregnant women may experience separation of the rectus abdominis muscle during pregnancy and delivery, which can lead to difficulties in fully restoring the abdomen to its unpregnant state after delivery. Also, a certain degree of laxity and stretch marks may remain in the abdomen after delivery. It is recommended that women who have had a cesarean section should promote abdominal retraction through appropriate postpartum belts, yoga exercises, sit-ups, and diet control.
