There are many causes of blood in the baby’s stool, including enteritis, constipation, colon polyps, and intussusception, etc. The treatment varies according to the cause. If your baby has blood in the stool due to enteritis and diarrhea, you will need to treat the enteritis. If the baby is constipated and the ambassador is too dry causing anal fissures and blood in the stool, the baby needs to be busy helping the child to pass the stool and to relieve the symptoms of constipation by adjusting the diet and other methods. It is recommended to apply erythromycin and other ointments to the small fissures in the baby’s anus to encourage the anus to heal as soon as possible. If your baby has blood in the stool due to a colon polyp that rubs the polyp when passing stool, you need to treat the colon polyp in a targeted manner. If your baby has blood in the stool due to intussusception, you will need to inflate the colon under X-ray monitoring, and if this treatment fails, you will need surgery to help reset the colon. A big reason for blood in the baby’s stool is that the baby’s diet is wrong. Parents are advised to pay more attention to the feeding of their babies, to maintain a balanced nutrition, to reduce the intake of protein, to allow the baby to eat more coarse fiber food and some fruits, and to give the baby more water.
