Mild diarrhea subsets can be improved by applying appropriate hot compresses and using montelukast and intestinal probiotics. Some people with diarrhea are caused by cold and chill in the intestines and the blood circulation of the intestinal wall is affected, which can be improved by applying hot compresses with towels. Hot towel compresses can improve the blood circulation of the intestinal wall, improve the function of the intestinal tract and relieve the contraction of intestinal spasms, so it can relieve diarrhea. Montmorillonite is an antidiarrheal drug that helps improve diarrhea by improving the defense function of the intestinal mucosa and at the same time adsorbing harmful substances in the intestinal system and promoting stool formation. The components of montelukast do not enter the human blood circulation, so it has fewer side effects on the human body and is suitable for a wide range of people. Some people have diarrhea due to imbalance of intestinal flora and need to pay attention to supplementing intestinal probiotics, such as Lactobacillus acidophilus, Lactobacillus casei and Bifidobacterium bifidum. Supplementation of intestinal probiotics can improve the function of the intestinal tract, which has a two-way regulation effect on diarrhea and constipation.
