What is the cause of long-term bleeding in stool?

It is normal for people to excrete food after eating grains. In 24 hours a day, the human body excretes feces, urine, sweat, etc. Today, let’s talk about defecation from a medical perspective. Speaking of feces, you must think that this dirty and smelly feces should be kept away from as much as possible, the better the hygiene. In fact, a person's physical condition can be observed from his bowel movements, so we need to study feces carefully.

Many people have the habit of taking a look at their stool after defecating. This is a good habit. Many diseases can be diagnosed from the stool. Let me tell you here that normal stool should be yellow and shaped very much like a banana. It is abnormal if there is blood in or outside the stool.

Many kinds of anorectal diseases will have the symptom of bloody stools. The specific diagnosis should be made based on a comprehensive analysis of the age of onset, the manner, amount, color of bloody stools, and whether there is pain. If the stool is tarry or black, the bleeding is mostly in the upper gastrointestinal tract, that is, the stomach and duodenum are most likely to be bleeding. If the blood is purple-red, mixed with mucus, and has a foul odor, the possibility of intestinal tumors, especially rectal cancer, should be considered. Generally, blood in the stool is bright red and in the form of drops attached to the surface of the stool. The bleeding site is mostly at the anus or not far from the anus, which may be hemorrhoids. But it is worth noting that if there is a large amount of bleeding in the upper gastrointestinal tract, the blood may be bright red because the blood stays in the gastrointestinal tract for a short time.

In order to diagnose the disease, examination becomes a crucial step. The amount of bleeding caused by some diseases is very small and is generally not easy to detect with the naked eye. However, a small amount of gastrointestinal bleeding is an important symptom of early colon cancer. If blood in the stool can be detected as early as possible, it will be beneficial for the diagnosis and treatment of the disease.

Regarding the problem of bloody stool, I believe everyone now has a clear understanding. When patients find themselves having symptoms of bloody stool, they should go to the hospital as soon as possible for treatment. Through clinical examination and various tests such as laboratory tests, X-rays, endoscopy, etc., it is necessary to determine the cause of the bloody stool and receive formal treatment as soon as possible.

After reading the above medical knowledge, I think you must have gotten rid of your prejudice against human feces. Normally, it is best for people to have a bowel movement in the morning, and at least once a day, because old stool is toxic. That is to say, if you don't have a bowel movement for a day, the dirt in the human body will accumulate in the body. Therefore, let us pay attention to every part of our body and our health.
