The fact that the stool always feels unclean indicates weakness of the spleen and stomach, inflammation of the intestines, and polyps. When the spleen and stomach function normally, the body can digest and absorb food normally, transport the absorbed nutrients to all organs of the body, and provide energy for the internal organs of the body. Once the spleen and stomach are weak, the absorption of nutrients will be affected, and the stool will contain a lot of water, which will cause the bowel movement to be unclean. The function of the intestinal tract is to absorb nutrients, promote feces, and help shape feces. Once there is inflammation in the intestinal tract, the function of the intestinal tract will be affected, and food residues in the intestinal tract will be quickly eliminated under the stimulation of inflammation, resulting in unclean stools. When there are polyps in the intestine, especially in the rectum, it will lead to a feeling of urgency and heaviness in the body.
