Intestinal dysfunction may be due to physiologic factors, acute enteritis, and intestinal flora imbalance. The symptoms of intestinal dysfunction can be improved by changing lifestyle habits, taking antibiotics and intestinal microecological agents. 1. Physiological factors: improper diet, consuming too much spicy and stimulating food leads to intestinal dysfunction. Symptoms can be relieved by establishing good living and dietary habits, quitting smoking, limiting alcohol and avoiding foods that may trigger symptoms. 2. Acute enteritis: Bacterial infection of the intestinal tract leads to intestinal dysfunction, which can be treated with antibacterial drugs such as azithromycin and norfloxacin, and the drugs should be taken according to the doctor’s instructions. 3. Intestinal flora dysbiosis: intestinal flora dysbiosis will lead to the reduction of probiotics in the intestinal tract, which will cause constipation, diarrhea and other intestinal dysfunction symptoms. Intestinal microecological agents such as bifidobacteria and lactobacillus can correct intestinal flora dysbiosis. Patients with intestinal dysfunction should go to the hospital in a timely manner, improve the examination, give targeted treatment after the cause is clear, follow the doctor’s instructions to use the relevant drugs, not blindly take drugs on their own, so as not to cause adverse consequences.
