First, the stool color changes.
Brown or brown
Yellow stool (or brown stool) is the color of healthy stool, and other colors may indicate disease? Omen? .
2. The surface is stained with bright red blood.
Let's rule out whether it's during menstruation. If the feces are in a certain shape and yellow in color, but there is blood on the surface, or there is blood when smeared with toilet paper, it usually means that the bleeding caused by rectal or anal problems may be caused by small tear (anal fissure) on the inner wall of the anal canal caused by excessive feces, or it may be caused by hemorrhoids. It may also be lower gastrointestinal bleeding caused by rectal polyps and tumors. Massive bleeding requires hospitalization and further evaluation, usually through colonoscopy, to determine the cause.
3, mixed with dark red
The stool is mixed with dark red or red-black blood, which is generally caused by intestinal diseases. Note that the stomach, large intestine and small intestine may be sick, so you should see a doctor in time.
4. Light brown or grayish white
The normal color of feces is brownish yellow. If it is light brown or grayish white, you need to check the liver. The color of feces is formed after bile produced by the liver enters the intestine, that is, fecal bile. When the biliary tract is completely blocked, the stool will be as white as clay. Gallstones, hepatobiliary tumors, etc. , will cause such a result. This is often accompanied by yellow urine, yellow skin and yellow eyes. At this time, you should go to the hospital for examination as soon as possible.
5. Green (surname); green
Green feces may be the reason for eating a lot of green leafy vegetables. But sometimes it is dark green, indicating that food crawls too fast in the digestive system, usually because the body doesn't have enough time to process bile into the brown it should be. If you don't eat a lot of green vegetables, you will have green, thin and sour stools, which may cause indigestion and intestinal dysfunction. If there is a lot of mucus in the green stool, beware of acute enteritis!
6. Black
This color may be bleeding somewhere in the gastrointestinal tract. This is because the color of blood is mixed with digestive juice and interacts with intestinal bacteria. If this happens, you need to see a doctor as soon as possible. In addition, pay attention to eating animal viscera, chicken blood, duck blood and so on. Or some drugs can also cause the feces to turn black, such as taking iron supplements (ferrous succinate) or some stomach medicines (bismuth), and some Chinese medicines can also turn black. If you haven't eaten it, you should be alert to upper gastrointestinal bleeding caused by ulcers. The most terrible things are probably esophageal cancer and gastric cancer.
7. Black and bright asphalt colors
Black, sticky and shiny, just like asphalt, be sure to pay attention! Explain that the amount of upper gastrointestinal bleeding is relatively large, and you need to see a doctor immediately!
8, with pus and blood
Abdominal pain and loose stool with pus and blood may be caused by bacterial enteritis, amebic dysentery and acute hemorrhagic necrotizing enteritis. It's all emergencies. Don't delay. In addition, one of the typical symptoms of inflammatory bowel diseases such as Crohn's disease and ulcerative colitis is purulent bloody stool. This is a common symptom of the disease, suggesting that the disease is active and should be treated as soon as possible.
Second, the change of fecal characteristics.
1, dry stool
With the decrease of water in the stool, the stool will become harder and harder, and finally it will become hard small pieces, just like sheep manure, one small and one small. Many constipation patients, the stool is like this, because there is not enough fiber in the stool to absorb water, keep the stool soft, and the water is too little, or the stool stays in the large intestine for a long time, which leads to excessive water absorption in the stool and finally becomes a hard dung ball.
2. Feces become thinner
The thinning of stool is mainly caused by intestinal stenosis, and there are roughly three reasons:
The first kind, intestinal benign tumor, a relatively large benign tumor will cause intestinal stenosis, which will lead to the thinning of stool.
Second, intestinal malignant tumors often cause defecation thinning or changes in defecation habits, and may also be accompanied by symptoms such as bloody stool and emaciation.
Third, occupying the space outside the intestine and oppressing the intestine will lead to intestinal stenosis and defecation thinning. No matter what the above reasons are, they all attract attention to seek medical treatment in time.
3. Loose feces
Feces are shapeless, but unlike diarrhea, diarrhea is usually a sign of food intolerance. Food will stimulate the digestive system, make the body produce mucus, and make the feces more fluid and loose and mushy than usual. Some common reasons include intolerance to dairy products. Usually taking probiotics can improve feces.
Third, the change of fecal odor.
1, the smell of defecation is worse than usual.
Under normal circumstances, although the stool has a bad smell, the taste is not particularly heavy, which is within the acceptable range of human sense of smell. However, if your stool smells bad, or it smells sour, burnt or rotten, you should be alert to whether there are health hazards in your stomach or whether your diet is unreasonable.
If feces become more smelly, it may mean constipation, feces stay in the body for too long, and bacterial fermentation in the colon will produce more gases, namely methane, sulfur, nitrogen, carbon dioxide and hydrogen. If diarrhea is accompanied by obvious odor, it may be a sign of viral or bacterial infection, such as salmonella. If these bacteria stay in the feces, they will produce and emit malodorous substances. It's time to see a doctor.
