Fall diarrhea is a seasonal, epidemic disease that, as the name implies, develops mainly in the fall and winter months, mainly from September to January each year, and according to epidemiological surveys, the incidence is highest during these months, from October to December. Before the onset of autumn diarrhea in babies, there are usually prodromal symptoms such as cold, stuffy nose, runny nose, cough and even vomiting, etc. Some babies also have fever, but the temperature is not too high, mainly low fever. The number of stools will increase in a day or so, from 3 to 5 times a day to more than 10 times a day in severe cases, with white or yellow egg-flake soup-like stools, watery, sometimes with mucus or blood, and rarely with odor. The age of onset of autumn diarrhea is most common between 6 months and 3 years old, because babies before 6 months of age are protected by antibodies from the mother, and their intestines are difficult to be invaded by viruses, especially breastfed babies, which have a very low probability of suffering from autumn diarrhea. Babies over the age of 3 years are becoming more and more resistant to autumn diarrhea as their resistance is improving and their gastrointestinal tract is basically mature. If we want to better prevent and control fall diarrhea in babies, we should know the causes of fall diarrhea. In western medicine, autumn diarrhea is mainly caused by viruses, of which rotavirus is the most common, mainly through the fecal-oral route of transmission, which is very contagious. In Chinese medicine, autumn diarrhea in babies is mainly caused by external wind and cold, wind and heat, and food injuries that cause the spleen and stomach to be incompatible, resulting in diarrhea due to dysfunction of the spleen ascending and stomach descending. The following to talk about the prevention of autumn diarrhea in babies: 1, dietary hygiene should be in the first place. As long as the entrance of things must be must be strictly disinfected. Bottles and tableware should always be disinfected by boiling water. 2, under one year old children as far as possible breastfeeding, breast milk can give children enough digestive enzymes and antibodies, for the prevention of autumn diarrhea is particularly important, of course, the nipple disinfection can not be ignored. 3, to prevent the abdomen from getting cold. You can give children to wear a belly band, which can block the invasion of hot and cold evil outside the body, to protect the gastrointestinal function. 4, often add some yam and coix rice to children’s food, can play a role in regulating the function of the spleen and stomach. Soaked milk powder should not exceed 2 hours at room temperature and should not be stored in the refrigerator for more than 24 hours, otherwise it will easily lead to bacterial growth and diarrhea. 5, drinks should not be unlimited, if thirsty, you can properly drink some warm boiled water, not too much to destroy the acidic environment of the stomach. For treatment, when autumn diarrhea occurs in early babies, add some antiviral drugs as early as possible, which can inhibit the replication and reproduction of the virus, reduce the number of viruses, alleviate the symptoms and shorten the course of the disease. Dehydration and electrolyte disorders caused by diarrhea in children can be fatal, so “oral rehydration salts” are especially important, and one bag mixed with 500 ml of water and drunk as tea can have the same effect as an infusion. Nowadays, fasting is no longer advocated for the treatment of diarrhea. Although fasting can reduce the burden on the gastrointestinal tract of the child, the hunger caused by fasting can aggravate the peristalsis of the stomach and intestines and increase the digestive juices, further aggravating diarrhea. In Chinese medicine, Chinese herbal medicine to strengthen the spleen and stomach to stop diarrhea, as well as pediatric massage and infrared abdominal physiotherapy are increasingly effective in treating diarrhea in infants and children, and are safe without any toxic side effects and easily accepted by parents.
