Long-term constipation: intestinal flora disorders will lead to a decrease in probiotics in the intestinal tract, a decrease in lactic acid secretion, and a slowing down of intestinal peristalsis, resulting in constipation. 2. Diarrhea: intestinal flora disorders affect the intestinal function, reduce the ability to absorb water, resulting in diarrhea. Diarrhea will lead to excessive discharge of things in the intestines, including probiotics, which will aggravate the intestinal flora disorder. 3. Repeated colds: intestinal flora disorders will make the body’s immunity decline, unable to resist the invasion of various bacteria and viruses, resulting in repeated colds. 4.
