Stool flocculation is caused by ulcerative colitis, intestinal dysfunction, acute enteritis and other reasons. Ulcerative colitis will have inflammation and ulceration of the colon mucosa during the attack, and the colon mucosa will even become necrotic and detached after a long period of time, and the necrotic and detached colon mucosa will be excreted along with the feces, resulting in white flocculent material in the feces. When intestinal dysfunction occurs, the intestinal absorption and secretion function will be affected, due to the inability to absorb the nutrients in the food, so the food residue will be rapidly discharged, and some of the food residue will appear as flocculent material when it is discharged. During the acute enteritis attack due to the inflammation of the intestinal mucosa caused by the stimulation of the intestinal mucosa, in severe cases will lead to intestinal mucosa detachment, so the feces will be accompanied by some flocculent.
