Why is constipation after childbirth?

Postpartum constipation occurs because of the loss of qi and blood and less activity after childbirth, so it will cause gastrointestinal function to decrease and gastrointestinal motility to slow down. Food stays in the intestinal tract for too long, water shortage will cause dry knot and other phenomena. Moreover, the contractile function of abdominal wall and pelvic floor muscles has not fully recovered after childbirth, so constipation will occur.
