In clinical practice, there are many more serious cases of blood in the stool that are not paid attention to. I will not give an example one by one. Let us take you to understand the common sense of blood in the stool.
In general, we routinely distinguish blood in the stool into upper gastrointestinal bleeding and lower gastrointestinal bleeding.
Upper gastrointestinal bleeding: mostly dark red bloody stools or black stools, tar-like. Lower gastrointestinal bleeding: mostly bright red or bright red blood.
The relationship between stool color and traits and disease:
Blood attached to the surface of the stool, dripping blood after stool, blood on paper towels, jet bleeding: consider rectal and anal canal diseases: common in hemorrhoids, anal fissures, mucosal damage, etc.;
Blood in the stool in children is usually caused by juvenile polyps or anal fissures;
Children with intussusception stools are jam-colored, and the disease may turn into dark red when the disease progresses;
Chronic non-specific ulcerative colitis and bacillary dysentery can be seen with blood in the stool, accompanied by mucus or pus (pus and blood in the stool), or with abdominal pain;
Intestinal cancer, blood in the stool is dark red, or accompanied by increased stool frequency, or tenesmus, progressive weight loss, and some with mucus;
Stomach ulcer, blood in the stool, tarry black stool;
Acute hemorrhagic necrotizing enteritis: watery, bloody stools, special fishy smell;
Some blood in the stool is normal, so don't worry: for example, eating animal blood, pig liver→black stool, false positive for occult blood; taking medicine: bismuth, iron, charcoal powder, Chinese medicine→feces gray and black and dull, occult blood is negative.
The above is very important for judging the source of blood in the stool, but the individual differences in the clinic and the progression of the disease cannot be used to determine the cause of blood in the stool. It is recommended to seek medical attention in time, especially if the medication is not effective. In the case of recurrent episodes, it is recommended to see a doctor in time to avoid delaying the condition
