According to the theory of Chinese medicine, the color, shape and smell of the stool often indicate the health of the body, and a healthy stool indicates a healthy body, and with a strong body, you will have a good life, and good luck will come naturally. Chinese medicine diagnostic method has four kinds of look, smell, ask and cut, which “look” includes the observation of two stool samples, different stools indicate the corresponding diseases, normal stools are yellowish-brown shaped soft stools, usually 1 to 2 times a day. Fresh Blood Stools containing fresh blood are often caused by bleeding in the lower part of the digestive tract, such as colon cancer, intestinal polyps, hemorrhoids, anal fissure, etc. The mucous membrane near the rectum is rich in blood vessels. The mucous membrane near the rectum is rich in blood vessels, and it is easy to damage the small blood vessels and cause rupture and bleeding when the stool is dry and constipated. Watery stool When suffering from intestinal infectious diseases, bacterial food poisoning, indigestion, due to the speeding up of intestinal peristalsis, a large amount of water is discharged along with incompletely digested food, which makes the stool watery or thin porridge-like. Mucus, pus and blood stools Inflammatory diseases of the lower part of the intestinal tract, such as bacillary dysentery, pathogenic Escherichia coli enteritis or ulcerative colitis, etc., the patient’s stools often contain mucus, a small amount of pus and blood. White clay-like stool Commonly due to gallbladder stones, cholangiocarcinoma, pancreatic cancer compression of the bile duct. Due to the complete obstruction of common bile duct, the stools are grayish-white due to the lack of fecal cholestrol, which looks like white clay. Asphalt-like stool Generally, it suggests that the patient has bleeding in the upper gastrointestinal tract in a moderate amount (60-100 ml) or more, commonly bleeding from gastric and duodenal ulcers and bleeding from varicose veins of the lower esophagus in the case of cirrhosis, and the blood flowing to the intestinal lumen is decomposed and destroyed by the intestinal fluids, which makes the stool turn into a black asphalt-like stool. Flat, long, flat stools often indicate narrowing of the lower end of the intestinal canal, such as rectal cancer or rectal polyps, anal stenosis. Rice soup-like stools are characteristic of cholera. A large amount of intestinal fluid is lost in a short period of time, and the absence of the colored substance bile pigment in this discharged intestinal fluid results in a rice-watery stool.
