1, color suggestion of stool
1. yellowish brown-normal state
In addition to gastrointestinal peristalsis for digestion and absorption, the human body also relies on gastric juice and bile to help and promote the digestion of food (bile mainly plays an important role in the digestion and absorption of fat). After the bile secreted by liver cells enters enterohepatic circulation, after a series of chemical changes, the yellow-green cholflavin in bile turns yellow-brown, and it is excreted with stool. So the poop is yellow normally. If pig blood or animal offal is eaten too much, it may turn reddish brown; Eating more green vegetables may turn green; Patients with gastropathy take stomach medicine containing bismuth, patients with iron deficiency anemia often supplement iron, and their stools will be black.
2. Black-upper gastrointestinal bleeding
If it is not the above situation that eating pig blood or drugs leads to black stool, it is generally considered as upper gastrointestinal bleeding. This is because the bleeding blood is destroyed by gastric acid through the long digestive tract, and the iron of red blood cells is released and combined with sulfide to form iron sulfide under the action of intestinal bacteria, thus making the feces appear black. However, it must be noted that the color change of stool during upper gastrointestinal bleeding is not the same, but quite different.
(1) When the amount of bleeding is small, the change of stool color cannot be found by naked eyes, and it can only be detected by special tests (such as occult blood test of stool);
(2) When the amount of bleeding reaches more than 50 ml, the color of stool turns black with naked eyes, which is a typical tarry black stool.
(3) It can also be brown, reddish brown or even bright red. Generally speaking, the higher the bleeding site, the darker the color of blood in the stool; The lower the bleeding site, the brighter the color of blood in stool, or it appears as blood. Of course, it also depends on the speed and quantity of bleeding. For example, the bleeding speed is fast and the amount of bleeding is large, and the blood stays in the digestive tract for a short time. Even if the bleeding site is high, the blood in the stool may be bright red. Only when the amount of bleeding in the upper digestive tract is small, the bleeding speed is slow, and the bleeding stays in the intestine for a long time, can it show a typical tarry black stool.
2, the reason why the stool is green
1. ate green food.
When people eat a lot of green food, such as vegetables or blue fruits, the stool will turn green. Because these foods will contain a lot of leaf green, and there will be some in the final excrement. For example, green drinks can also have green stools, or some drugs can also cause green stools.
2. Dyspepsia
If it is indigestion, the color of stool will appear green, and the stool will also appear green in the case of gastrointestinal disorders.
3. Intestinal inflammation
If the stool is green and accompanied by foul smell, it may be caused by enteritis, especially acute enteritis, or dysentery, diarrhea, etc., and people who receive more antibiotics will also have green stools.
Note: Long-term green stool has a high probability of enteritis, so it is recommended to go to the hospital for examination in time.
People have to go to the toilet, so they need to go to the toilet when urinating and defecating. Some people defecate in the morning, while others defecate at night. There is no time limit.
