1. It is considered to be caused by gastrointestinal dysfunction and indigestion. Pay attention to your diet and avoid cold and spicy foods.

4. Green stool in adults is greatly affected by diet. If you eat a lot of high-fiber green vegetables or the acidity in the intestine is too high, the stool will also turn green, which is normal.

Normal stool should be yellow-brown. This is because after the bile secreted by liver cells enters the enterohepatic circulation, it undergoes a series of chemical changes, and the yellow-green biliflavin in the bile turns into yellow-brown and passes through the stool. Excreted from the body. If your stool is very dark in color, there are generally several possibilities. The first is related to food. There is an old saying among Guangzhou people: If you eat pig blood or animal viscera, your stool will turn red and black. If you eat more green vegetables, the chlorophyll content will be high and your stool will be black. Green. The second is related to drugs. Patients with stomach problems take gastric medicine containing bismuth, and patients with iron deficiency anemia often take iron supplements, and their stools will also turn black. Charcoal and some black proprietary Chinese medicines can also cause black stools. This kind of black stool is a matte charcoal black in varying shades. The reasons for dark green stool in adults are probably as follows: First, when the stool is acidic, the bile contained in the stool oxidizes to green when exposed to air. Bilirubin in bile is a yellow pigment that stains the feces yellow. After oxidation, the bilirubin becomes biliverdin, which makes the feces appear green. In addition, due to the effect of Lactobacillus bifurcatum, the intestines have become acidic, and the stool has been oxidized in the intestines and turned green before being excreted. Therefore, dark green stool is not abnormal, it is a normal phenomenon, and there is no need to worry about it. Dark green stool may be a sign of indigestion. You can adjust your diet and then observe the changes in your stool. The stool is green, watery or pasty, has a sour smell, and is foamy. It is more common in diseases such as indigestion and intestinal dysfunction. If the stool of infants and young children is green, it is diarrhea, accompanied by watery or mushy, foamy, and sour smell symptoms. Abnormal color of stool is related to diseases. The following is the relationship between abnormal color of stool and diseases. Gray-white: If the color of the stool is like white clay, it may be jaundice or bile duct obstruction caused by stones, tumors, roundworms, etc., resulting in the inability of biliflavin to be excreted with the stool. Black: If you don’t take pig blood or drugs that may cause black stools, black stools usually indicate bleeding from the upper gastrointestinal tract. In gastric and duodenal bleeding, the blood passes through the several meters long intestine and undergoes various chemical changes and gradually turns black. Therefore, if the amount of bleeding in these places is not large, the stool should be black. Among patients with upper gastrointestinal bleeding, about half of the bleeding is due to ulcer disease, and most of them are due to duodenal ulcer bleeding. In addition to ulcer disease, gastritis, liver cirrhosis combined with esophageal or gastric variceal varices, and gastric cancer are also common causes of upper gastrointestinal bleeding. Red: Bloody stools are mostly caused by bleeding from the lower gastrointestinal tract. The lower gastrointestinal tract includes the jejunum, ileum, rectum, and colon. Due to the short distance and few chemical changes, bleeding in these parts will cause the stool to be red. If the amount of bleeding in the upper gastrointestinal tract is large, the blood will not have time to stay in the intestines for too long, and the stool will also be red.
