上厕所便中带血!别慌!教你如何区分病症

What are the main causes of hematochezia?


First, diseases of the digestive tract itself, such as bleeding from esophageal or gastric varices, gastric and intestinal ulcers and inflammation, parasitic infections, tumors (including polyps and cancer), hemorrhoids, intussusception, anal fissure, dry stool scratches, etc.


In addition, diseases of other systems outside the digestive tract, such as blood diseases, acute infectious diseases, vitamin deficiency, poisoning or drug toxicity.


Some people have bloody stools that are bright red, while some people have dark stools. What diseases might these different symptoms of bloody stools indicate?


There are many kinds of stool bleeding.


The first is blood stool, which is common in clinical practice.


Hemorrhage is caused by hemorrhoids, generally internal hemorrhoids or mixed hemorrhoids. There is more or less bleeding, and the less may be toilet paper with blood or stool dripping. If there is more, there may be jet bleeding.


Usually bleeding and defecation do not mix.


The blood in stool caused by anal fissure is generally caused by hard stool. The way of bleeding is that there is blood stain on the side of stool, the stool surface is not contaminated, and some of them drip blood after stool.


There are also bloody stools caused by intestinal polyps. The color of bleeding varies with the location of polyps.


If the polyp is in a lower position, the bleeding will be bright red. If the polyp is in a higher position, the bleeding may be dark red.


There are also some other diseases, such as rectal prolapse, rectal prolapse with bleeding, which generally has a long course of disease and produces blood.


Second, bleeding is mucus purulent bloody stool, which is also common in clinical practice, and is also a relatively easy cause of panic.


If the excreted stool contains both pus (mucus) and blood, it is necessary to first consider whether there are tumors and inflammation in the rectum or colon.


Generally, it is accompanied by changes in stool properties and abdominal pain. If these conditions are not found, you should go to the hospital for examination as soon as possible.


The third kind is black stool, which is also called tarry stool. The stool is black or brown black, which is one of the most common symptoms of upper gastrointestinal bleeding.


For example, the amount of bleeding is small, the bleeding speed is slow, the blood stays in the intestine for a long time, the stool is black, the amount of bleeding is large, the time of staying in the intestine is short, the blood output is dark red, the amount of bleeding is especially large, and the blood quickly becomes bright red.


There is also a kind of occult blood stool, which is invisible to the naked eye, but it is positive when doing stool occult blood test. All diseases that cause gastrointestinal bleeding will have occult blood stool, common ulcers, inflammation and tumors.


Fecal occult blood may be positive in early intestinal polyps (tumors).


Regular detection of fecal occult blood is an important method for primary screening of colorectal cancer.


What are the symptoms that require special attention?


Many patients will be nervous because of stool bleeding. Let's talk about it here.


If there is blood in stool, most of them are perianal diseases, but if there is mucopurulent stool, we must be alert, because mucopurulent stool may be a sign of tumor, especially accompanied by abdominal pain, urgency of urination, and heavy anus, so we must go to the hospital as soon as possible.


We can do digital anal examination first, and further colonoscopy if necessary to confirm the diagnosis.


Blood in stool is not the patent of adults. What is the reason why many parents find that their children have more blood in their stool?


In clinic, children often have feces, most of which are due to anal fissure. Children may be playful at ordinary times and do not defecate in time. Even many gifted children defecate. Some infants drink milk powder for a long time, which is also easy to cause constipation. Constipation causes anal fissure bleeding. Children usually have anal pain, which can be seen by their parents.


There are also some bleeding, if there is no anal fissure, and the stool is not dry, you should be alert to intestinal polyps or other diseases.


Intestinal polyps are red and painless, and blood does not mix with stool; Bacterial dysentery, intussusception and blood system diseases may also occur.


What harm will blood in stool do? Or cause other diseases.


The hematochezia is generally long-term chronic bleeding, which is well tolerated by patients, but it often causes severe anemia patients due to long-term hematochezia.


Therefore, long-term hematochezia can cause severe anemia, and many patients may be accompanied by dizziness, fatigue, confusion, inability to do heavy work, and inability to walk.


If the pregnant woman has long-term blood in stool, it will affect the fetal development.


How to prevent hematochezia caused by hemorrhoids and anal fissure?


The anal fissure caused by hemorrhoids and stool is usually blood. It is OK to have a small amount of bleeding occasionally. Don't panic. Keep the stool smooth. It is recommended to eat more vegetables and fruits, drink more water, and defecate for a short time and not too hard.

If the amount of bleeding is relatively large, which is manifested as jet flow bleeding, you need to see a doctor in the hospital and apply some hemorrhoids drugs to treat it.
