Our gastrointestinal system has 65438+ billion nerve endings, which is equivalent to the second brain of the body. Any problem in the gastrointestinal system may affect our mood, memory, and even the immune system, causing diseases. The color, smell and frequency of feces discharged through gastrointestinal tract can reflect the digestive health.
1, the relationship between stool color and health
1. Black stool.
Mayo Clinic believes that if your stool is black and non-pathological, it may be related to diet. For example, eating foods rich in iron or taking drugs such as blood-enriching iron, black licorice, bismuth basic salicylate (used to treat stomach diseases) will cause melena. To rule out the above reasons, we need to consider pathological reasons, such as upper gastrointestinal bleeding, especially gastric bleeding.
2. Light or white stools
If your stool is white, it may mean that there is not enough bile in your stool, which means that your bile duct is blocked. This may be caused by taking antidiarrheal drugs or other drugs.
3. Yellow or greasy stool
The stool is yellow and greasy, and sometimes it even smells bad, indicating that your diet is unreasonable and you have too much fat intake. In addition, it may also mean that you have intestinal damage or malabsorption, such as lactose intolerance. Due to the lack of lactase, the body can't completely decompose the ingested lactose, and the absorption disorder makes the food difficult to digest.
4. Green stool
Green feces means that the food you eat passes through the intestine too fast for bile to break it down. The common reason is that you eat too much green pigment, such as vegetables with many leaves.
5. Red stool
It is usually hematochezia caused by hemorrhoids or anal canal rupture. However, because intestinal cancer also has symptoms of bloody stool, if it can't be clearly distinguished, the child had better find a doctor to check and prescribe the right medicine.
2, stool smell and intestinal health
It is normal for stool to smell, but if the smell is unbearable, it may be malabsorption, leading to intestinal infection and even allergies. If your feces always stink, you'd better go to the gastroenterology department.
3. The frequency of defecation and the health of digestive tract
Generally speaking, it is normal to defecate three times a day or three times a week. If you don't defecate for three days in a row, it is constipation. If you find yourself constipated, you can try to improve your diet, squat in the toilet, or see a doctor to take some medicine. And defecating more than three times a day will be considered diarrhea.
