After the birth of the stool dry and bright red blood drops out, generally speaking is the most likely anal fissure, this is because after the birth of the abdominal muscle mostly loose, pelvic pressure is low, intestinal peristalsis slowed down, stool storage too long, excessive absorption of water and dry, defecation is very difficult, easy to cause anal fissure. In addition, pregnancy can also cause obstruction of venous reflux around the anus, resulting in internal hemorrhoids and bleeding symptoms. How to diagnose blood in the stool Postpartum blood in the stool can be examined by electronic anoscopy to clarify the cause, hemorrhoids blood in the stool jet-like outflow or dripping blood after the stool; anal fissure blood in the stool is small, but anal pain is more intense.

The presence of tarry stools indicates that the amount of bleeding has reached 60 ml or more. However, it should be noted that certain foods and drugs can make the stool black, and can be identified by stool occult blood test. Third, the causes of postpartum stool bleeding Women in the postpartum period because the body has not yet recovered, coupled with vaginal dilatation, tearing involving the anus during childbirth, constipation and other factors, it is easy to lead to anal fissures. According to the survey data of the International Health Organization, as many as 80% of pregnant women are constipated, and more than 85% of anal fissure patients have constipation symptoms. 1, after the delivery of long-term bed rest, little activity, intestinal peristalsis slowed, while the abdominal wall expansion during pregnancy, postpartum abdominal wall relaxation weakness, abdominal pressure is reduced. This will make the intestinal contents easy to stagnate in the intestinal cavity, difficult to discharge. 2, because the postpartum diet is not proper, too much fine food, not eat or rarely eat vegetables, fruits and other fiber-rich food, some people also drink less water. This will inevitably occur constipation and induce anal fissures. 4, how to prevent stool bleeding after childbirth 1, eat more soluble fiber-rich foods: such as oats, whole grain foods and brown rice, vegetables and fruits.
