What are the symptoms of intestinal bleeding stool color?

Intestinal health is the most important thing for the body because the function and position of the intestine inside the body are very important. It is the place where complex food is digested and nutrients are absorbed. It is like an energy acquisition center for people. However, intestinal diseases can have a great impact on the body, especially intestinal bleeding, which is extremely harmful. Let’s take a look at the manifestations of the color of stool due to intestinal bleeding.

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.

Black stools

It refers to black or brown-black stools, also known as tarry stools, which is one of the most common symptoms of upper gastrointestinal bleeding. Upper gastrointestinal bleeding mainly manifests as black stools, often accompanied by other symptoms and signs such as vomiting blood, palpitations, fatigue, and anemia. If the amount of bleeding is small and the speed is slow, the blood stays in the intestine for a longer time, and the stool discharged is black due to the effect of intestinal fluid; if the amount of bleeding is large and the blood stays in the intestine for a shorter time, the discharged blood is dark red; if the amount of bleeding is particularly large and is discharged quickly, it may also be bright red.

Occult blood in stool

Any small amount of gastrointestinal bleeding that does not cause changes in stool color and only tests positive for occult blood in the stool is called occult blood in stool. All diseases that cause gastrointestinal bleeding can cause occult blood in the stool, the most common of which are gastric ulcers and gastric cancer. A fecal occult blood test detects small amounts of blood in the stool. Multiple and persistent positive occult blood tests indicate chronic gastrointestinal bleeding and further examination should be conducted to alert the presence of gastrointestinal tumors. .
