1. What is blood in the stool
Blood is discharged from the anus, and the color of stool is bright red, dark red or tarry (black stool), which is called blood in the stool. Blood in the stool is just a symptom, not a disease. Hematochezia is more common in lower gastrointestinal bleeding, especially bleeding from colon and rectal lesions, but it can also be seen in upper gastrointestinal bleeding. The color of blood in the stool depends on the location of the gastrointestinal bleeding, the amount of bleeding and the time the blood stays in the gastrointestinal tract.
2. What kind of blood in the stool should go to the hospital?
Once there is blood in the stool, I suggest that you should go to the hospital in time. Don’t just diagnose yourself as "hemorrhoids"
3. What to tell the doctor when you have blood in the stool
As a patient, when blood in the stool occurs, pay attention to the following conditions. This is also what you need to tell your doctor when you see a doctor.
1. Pay attention to the characteristics of blood in the stool, understand the occurrence and development process of blood in the stool, and it is very necessary to observe your stool every time.
2. Distinguish the characteristics of blood in the stool, bleeding pattern, color and amount of bleeding. This helps the doctor to judge the direction of diagnosis and perform auxiliary examinations purposefully.
3. Pay attention to the accompanying symptoms of blood in the stool, such as pain, abdominal pain, and anal pain.
Four, common causes of blood in the stool
1. Bloody stools are common in diseases such as hemorrhoids, intestinal polyps, rectal prolapse, anal fissure, etc.
2. Pus blood/mucus blood in the stool is common in diseases such as rectal cancer, colon cancer, ulcerative colitis, intestinal infectious diseases, etc.
3. Black stools, also known as tarry stools, stools are black or brownish-black, and are one of the most common symptoms of upper gastrointestinal bleeding.
4. Occult blood in the stool A small amount (minor amount) of gastrointestinal bleeding will not cause the color of the stool to change. It is only positive in the stool occult blood test, which is called occult blood in the stool. All diseases that cause gastrointestinal bleeding can cause occult blood in the stool, common ulcers, inflammations and tumors. Early fecal occult blood of intestinal polyps (cancer) can be positive, and regular fecal occult blood testing is an important way of colorectal tumor screening (primary screening).
