Lower gastrointestinal bleeding, dark red or bright red bloody stools. However, both can be exceptions. Acute upper gastrointestinal bleeding associated with bowel movements accelerated, it can emit more red blood without dark will. Small intestinal bleeding, such as blood stay in the intestines for a longer time, can be presented tarry black stools; intestinal bleeding, discharge faster when the blood in the stool dark red or even was more bright red loose stools. colon and rectal bleeding, blood stays in the intestines short time, tend to emit a bright red or bright red blood will.

2. parasitic infections such as hookworm, schistosomiasis, etc.;
3. tumors, such as cancer, colon cancer, intestinal polyps;
4. intestinal blood circulation disorders, such as hemorrhoids, intussusception, intestinal strangulation, etc.;
5. injury, such as anal fissure, equipment inspection, or dry stool abrasions.
second other systems outside of the intestinal disease, can be divided into:
1. blood diseases, such as various types of purpura, leukemia, hemophilia, etc.;
2. acute infectious diseases, such as epidemic hemorrhagic fever, leptospirosis, etc.;
3. vitamin deficiency, such as lack of vitamin c or K;
4. poisoning or drug toxic effects, such as bacterial food poisoning, mercury poisoning. Typically, children with blood in the stool of the main reasons is the rectal polyps or intussusception is more common in young people in the stool hemorrhoids, anal fissure, and colitis, blood in the stool of the elderly accompanied by change in bowel habits, to take into account the possibility of intestinal tumors sex.
lead to blood in the stool of the diseasemany anorectal diseases, not just hemorrhoids can cause blood in the stool, and other anorectal diseases, such as anal fissure, rectal polyps, colon polyps, ulcerative colitis and even rectal cancer and will appear in stool. However, each anorectal diseases caused by blood in the stool in the color of blood or other symptoms are different.
First, hemorrhoids: blood in the stool generally occurs in the defecation process and after, showed a drop of blood or jet-like, blood red, blood and stool do not mix. bowel bleeding caused by hemorrhoids, a bowel movement, blood often mixed with the stool, sometimes accompanied by hemorrhoids prolapse, the formation of edema, incarceration pain, severe hemorrhoids patients suffering from hemorrhoids can lead to anemia.

stool is how is itanal fissure is the most common cause of lead to children with blood in the stool. Children in the blood in the stool at the same time, there are symptoms of pain after a bowel movement. anal fissure in adults are mostly caused due to chronic constipation.
