The stool becomes dry and hard, and it is very difficult and laborious to discharge. This is what people often say is that the stool is dry. How to cause dry stool is mainly caused by two factors. The first factor is that the stool stays in the large intestine for too long, and the second factor is that too much water is absorbed, which will lead to dry stool. Dry stool is a very painful disease. If the stool is too dry, it will not only be difficult and laborious to discharge, but also lead to some other diseases, such as anal fissure. If the stool is dry and the defecation time interval is too long, it is called constipation, and this will increase the risk of constipation, For human beings, it is necessary to correct the situation, whether it is subjective, objective, or some of the later negative effects. From the perspective of colon peristalsis and water absorption, how to prevent dry stool? First, drink more water. If the water is too little, the body will absorb too much water back from the stool, which will lead to dry stool. So drink more water, and the body needs enough water. OK, from the stool, the body will keep the corresponding water without too much absorption, The second is some foods that can keep the stool volume moist, rich in water, and prevent the stool from drying. These foods are foods rich in plant fiber, namely dietary fiber, such as oats, such as sweet potatoes, etc. These coarse grains will keep the water in the stool and prevent the stool from drying. If the stool is really dry, or even cannot be discharged for a long time, when it is difficult to discharge, you may need to go to a doctor, and then there will be some means to help, such as some lubricants, or even more active means to help eliminate these dry stools.
