Stool, a substance excreted by the body, is yellowish in color and has a foul odor. Physical health is closely related to intestinal health, and intestinal health is closely related to the condition of the stool. On the one hand, by observing the shape, color and smell of the stool, you can determine whether the intestinal tract is healthy. If the stool is not normal, we should pay great attention to the intestinal tract to do a good job of maintenance, to prevent disease. On the other hand, by observing the changes in the details of the stool, we can also determine the effect of our intestinal care, in the end, how. Defecation is very important to the human body, the time, number, shape and smell of the daily bowel movements you pay attention to? A, from the shape of the stool to determine the health 1, banana-shaped: if the daily discharge of such poop, then your intestines are healthy. 2, lumpy: little water content in the stool, defecation strain, which is a sign of weak intestinal movement, often discharge this kind of stool generally indicates intestinal lesions, such as various inflammatory diseases, and sometimes even cancer. 3, mud: mud-like stool informed the intestine has been full of stool, intestinal movement is greatly impeded, long-term malnutrition, which leads to a variety of diseases. 4, watery: this kind of stool is very dangerous new number, it is usually a sign of some malignant disease, intestinal movement almost stagnant, food and water is excreted unchanged. 5, hard state: the discharge of this kind of stool indicates a lack of water in the body, intestinal movement is not too comfortable, so the stool is easy to accumulate in the intestines, the formation of stool, the root cause of various diseases. 6, semi-chain: stool in the water, indicating that the intestinal absorption movement problems, can not fully absorb water, the nutrients can not be well absorbed. B, from the stool color and stool substances to determine the health 1, if the stool color is normal, it is yellow, which is the performance of the gastrointestinal tract health. If the color appears abnormal, then we should be careful may have a disease. 2, the stool is black or brown, this is a warning sign, but no need to panic to go to the hospital, as long as you maintain a healthy diet, it can appear yellow, but if the stool is darker than usual, or purple, you must pay special attention, this may be the stomach or intestinal bleeding. This is a condition where blood is mixed into the stool, and before it is excreted, the color changes from red to black. There are various types of dark stools, such as tarry stools, may be suffering from stomach ulcers, duodenal ulcers or stomach cancer disease. 3. Some people have stools that contain almost none of the components of normal stools, but a mixture of blood and mucus, called sticky blood stools. This type of stool is sometimes accompanied by severe abdominal pain or vomiting symptoms, at this time may be suffering from intestinal entrapment, intestinal torsion, intestinal infarction and other diseases. 4. If there is oil and pus mixed in the sticky blood stool and it continues for several days, it is very likely to have colorectal cancer. If a person with constipation pulls out black hard stool, it may also be a sign of colorectal cancer, which is caused by bleeding somewhere in the large intestine, which turns black after accumulating in the intestine for a long time. C, from the smell of stool to read health “stool is smelly”, this is thousands of years people’s deep-rooted concept, but scientific analysis shows that the stool should not be smelly. Healthy stools do not have too obvious bad odor, while the stools of constipated patients or friends who like to eat meat emit bad odor, which is the bad gas emitted by harmful bacteria in the intestinal tract after decomposing food. In addition, patients with constipation produce a lot of toxins that are harmful to the human body due to abnormal fermentation and corruption as the stool stays in the intestinal tract for too long. Therefore, when people have health problems such as hemorrhoids, facial pigmentation, and anal diseases, they are usually due to constipation. The main components of stool odor are indole, fecal odorant, hydrogen sulfide, amine, acetic acid, and butyric acid. Among them, indole and fecal odorant are the root cause of bad odor, which is a substance formed when protein is broken down by bad bacteria in the intestine. In other words, if a large amount of high protein is consumed, the stool will become smelly. And all these things are toxic to the human body, and they are not contained in the stools of people with normal intestinal tracts – such as babies. The stool that infants pass before the weaning period is clean, tastes sweet and sour, and does not stink at all. As the appropriate amount gradually increases after weaning, the stool becomes as smelly as that of an adult. The reason for this is that babies are fed with breast milk, which keeps the intestines very clean and the intestinal tract is very active, and after they start eating, they absorb a lot of high-fat, high-protein food, which damages the intestinal environment and gradually produces decaying substances, and the stool gradually forms, causing the stool to stink. If the toilet is full of bad odor, it means that the corruption in the intestine has been very serious, which is bound to seriously affect our health. The older a person gets, the more sluggish the intestinal movement becomes, the more likely it is that constipation and other diseases will occur, and the more smelly the stool will be. Aging begins in the intestines, and foul-smelling stools are the strongest evidence of aging and deterioration of the intestines. Sometimes the stool also emits a strange smell, which is often a sign of intestinal pathology, must be taken seriously. For example, a pungent sour smell in the stool may be caused by abnormal fermentation in the intestine (so-called fermentative dyspepsia), in which case the diarrhea stool is yellow in color. Therefore, both color and odor must be carefully observed. In addition, if the diarrhea stool has a burnt smell, it is possible that the small intestine function is reduced caused by indigestion, with a fishy smell of tar-like stool, indicating that the digestive tube has a bleeding condition, and the amount of bleeding is quite large. D, the number of stools to see the health In general, normal people defecate 1 to 2 times a day, some 2 to 3 days once (as long as no defecation difficulties and other discomfort are normal), but most people (about 60% of more) for a daily defecation.
