I. Overview of intestinal dysbiosis This disease is mainly caused by improper use of antibiotics and other treatments for intestinal immune dysfunction, and the clinical manifestations are mainly severe diarrhea or chronic diarrhea. The key to this disease is prevention, mainly the rational application of antibiotics. For the old and weak, chronic wasting disease patients, when using antibiotics or hormones, we should strictly grasp the indications, it is best to do drug sensitivity test to select the type of antibiotics. For the weak body can take vitamin C or B vitamins and with the use of lactobacillus preparations. Second, the treatment of intestinal flora dysbiosis The key to the treatment of the disease is to adjust the flora. The first is to adjust the acidity and alkalinity in the intestine, because it will affect the growth of bacteria, aerobic bacteria and Escherichia coli secreted enzymes, will be bile acid decomposition into secondary bile acid, and induce the occurrence of colorectal cancer; if too much protein intake, in addition to being digested into amino acids and absorbed, a small amount of unabsorbed protein will also be used by harmful bacteria (such as Clostridium perfringens) to create ammonia, hydrogen sulfide and other foul-smelling toxins. Therefore, carnivorous animals have more alkaline intestines, more Clostridium perfringens, and more smelly feces. When there are more beneficial bacteria, the intestine is weakly acidic. At this time, anaerobic bacteria such as Lactobacillus and Bifidobacterium will break down sugars and fibers and produce short-chain fatty acids to lower the pH of the intestine and inhibit aerobic bacteria. They also synthesize B vitamins and vitamin K, which are beneficial to the secretion of enzymes and the production of immunity. Beneficial flora have the following benefits to human body: promote intestinal peristalsis, prevent constipation, reduce toxin absorption by the body, reduce the incidence of colon and rectal cancer; improve diarrhea, dysentery and other indigestion, with the effect of stomach and intestine; inhibit the activity of pathogenic bacteria and carcinogenic substances in the intestine; promote the synthesis of 8 vitamins, vitamin E, vitamin K, folic acid; can hydrolyze and digest lactose, improve lactose intolerance; improve nutrient absorption. Tolerance; improve nutrient absorption and disease immunity; can effectively make the metabolism of calories flourish, and then decompose the excess fat in the body. Therefore, the flora adjustment therapy based on live bacterial preparation containing beneficial bacteria, supplementing a large number of beneficial intestinal flora, can make some diarrhea patients get relief or cure. In addition, after Lactobacillus is in the dominant strain in the intestine, the digestive system will not send hunger signals to the brain, so that the diet is normal, the amount of food is moderate, obesity can also be improved, and can reduce the load of various organs, to achieve the effect of slimming and beauty, strengthening the body. Bifidobacterium bifidum and other intestinal normal flora of live bacteria preparations, through the improvement, regulation of intestinal flora dysbiosis, to achieve the role of antagonism, inhibition of germs. Commonly used drugs are: Lizhu enteral, whole intestine, polygamy, Si Lian Kang, etc.
