When constipation occurs after childbirth and there is anal bleeding, it may be due to fissures caused by constipation or hemorrhoids causing blood vessel rupture and bleeding. Postpartum, due to the reduced activity of the mother and the consumption of too refined foods, waste cannot be smoothly expelled, leading to difficulty in defecation due to fecal impaction. During straining, this might cause rupture of the anus or fissures, or lead to hemorrhoids by disrupting local blood circulation. It is advisable to go to the hospital for a check-up to see if it is serious, and if necessary, treatment to stop the bleeding may be required.
