Poorly formed stools and exhaustion are mostly associated with colitis, irritable bowel syndrome, and imbalance of intestinal flora. The colon is located below the small intestine and its main role is to absorb water from food residues and promote stool formation. During a period of colitis disease, the impaired function of the colon prevents it from shaping the stool, resulting in an unformed stool. The absorption of gas in the intestinal lumen by the intestinal wall is also affected during an episode of colitis, and there will be hyperactive bowel movements and a relative increase in the frequency of exhaustion. There are many types of irritable bowel syndrome, and when the main manifestation is hyperperistalsis and impaired absorption, the patient will experience irregular bowel movements and an increase in the number of bowel movements. When there is an imbalance of intestinal flora, a large number of harmful bacteria will grow in the intestine, which will not only affect the absorption function of the intestine, but also react with food residues to produce more gas, resulting in the symptoms of unformed stools and increased exhaustion.
