Excessive bowel movements are always stools, which are associated with ulcerative colitis, acute enteritis, imbalance of intestinal flora, and irritable bowel syndrome. In ulcerative colitis, the lesion is located in the colon area, and the function of the colon is affected because the mucosa is damaged by colitis. Most patients with ulcerative colitis have a rapid bowel movement and have an increased number of bowel movements and loose stools. When eating unclean food or eating irritating food, the food will cause irritation to the gastrointestinal mucosa, which will not only cause nausea and vomiting, but also the intestine will move too fast when stimulated, and the chyme in the intestine will be excreted without the nutrients being absorbed, so the number of bowel movements will increase. With a balanced intestinal flora, not only will the intestinal immunity be enhanced, but also the function will be better. Once there is an imbalance of intestinal flora, some harmful bacteria will cause stimulation to the intestine and stomach, leading to hyperactive intestinal peristalsis, and stools will be expelled quickly. Some people suffer from irritable bowel syndrome, a disease that causes the intestines to move at a hyperactive rate, so the number of bowel movements will also increase.
