What is the color of stool for upper gastrointestinal bleeding

It is very common to see blood in the stool, but to find out the cause, you need to investigate carefully. If the blood in the stool is caused by upper gastrointestinal bleeding, the color should be dark red. It is recommended that in such cases, you go to a regular hospital for examination and diagnosis before receiving treatment.

Bloody stools

Most of the time, the bleeding is immediate, and the blood flows out of the blood vessels and is discharged through the anus with feces in a short time, or flows out directly after defecation. The appearance of the blood flowing out is similar to that of bleeding from external injuries, and its color is bright red, purple red, or dark red. It can coagulate into blood clots after a while. Blood in the stool is often seen in the following diseases:

1. Hemorrhoids: Internal hemorrhoids of all stages and mixed hemorrhoids can cause bleeding in the stool, usually with fresh blood in the stool or blood dripping after defecation. External hemorrhoids generally do not cause bleeding in the stool.

2. Rectal polyps: painless bleeding in the stool. Bleeding occurs during bowel movements and stops after bowel movements. The amount of blood varies. Generally, the blood is not mixed with feces. However, if the polyps are located high and the number is large, they may also be mixed with feces.

3. Rectal prolapse: Bleeding during defecation may occur after a long illness.

4. Anal fissure: blood in the stool. The bleeding pattern is blood on one side of the stool surface, which is not mixed with the stool. Some patients have blood dripping after defecation. To determine whether the above diseases are the cause of bloody stools, an electronic anorectal endoscopy can be used for examination and diagnosis. At present, some hospitals use imported high-definition anorectal endoscopes (such as the Anorectal Surgery Center of the First Branch of the 309th Hospital of the People's Liberation Army in Beijing), which can magnify the lesion site dozens of times and effectively discover the cause of bloody stools.

Bloody stool

That is, the excreted feces contain both pus and blood. The blood is thinner in appearance and sometimes contains a large amount of mucus. Bloody stools containing pus or mucus are often seen in tumors and inflammation in the rectum or colon. Here are some common diseases:

1. Rectal cancer: The blood is fresh or dark red, and there may be mucus in the stool. Blood, mucus and stool are often mixed.

2. Colon cancer: As the disease progresses, bleeding in the stool gradually occurs, mostly bloody stools containing pus or mucus, and the blood is darker in color.

3. Ulcerative colitis: mucus or bloody stools, accompanied by left lower abdominal pain or lower abdominal pain.
