Mild diarrhea is very common among infants. Not only can bacteria and viruses upset their intestines, but even new foods and too much juice can make them feel uncomfortable. The good thing is that this discomfort is usually mild and does not have serious consequences. The child may pass two more loose, soft stools than usual, the stools may be greenish in color and smell different than usual. The most important characteristic of this mild diarrhea is that the infant behaves normally or almost normally. The child remains playful and active, and urinates as much as usual. If there is any sign of illness, it is only a slight decrease in appetite and a little bit of nasal discomfort. Usually no special treatment is needed and the symptoms will disappear in a few days. You can give your child a little more water, continue to stick to a normal diet, and let him eat as much as he can, but don’t add new foods for a while. This is what is best for him. If the diarrhea lasts for more than two or three days, even if your child is still acting healthy, you should check with your doctor. There are two peak incidences of pediatric diarrhea in China each year, occurring in June, July and August, called summer diarrhea, where the main pathogens are diarrhea-causing E. coli and Bacillus dysenteriae; occurring in October, November and December, called autumn diarrhea, where the main pathogen is rotavirus. The most likely diagnosis can generally be estimated based on stool characteristics, season of onset, age of onset, and prevalence. For example, in children under 2 years of age, if the watery stool diarrhea occurs in autumn and winter, rotavirus enteritis is more likely; in summer, toxic E. coli enteritis is more likely; mucopurulent stools should be considered bacterial dysentery, in addition to other invasive bacterial infections, such as invasive E. coli enteritis. Older treatments emphasized fasting, excessive application of intravenous fluids, and misuse of antibacterial drugs. The Chinese Diarrheal Disease Diagnosis and Treatment Program sets out the principles of treatment for pediatric diarrheal disease as – prevention of dehydration, correction of dehydration, vigorous promotion of oral rehydration, continuation of diet, and rational use of medication. At the beginning of diarrhea, children should be given more fluids by mouth to prevent dehydration, such as rice soup with salt solution, sugar saline, oral rehydration salt solution, any one of them, and 40-50 ml of solution by mouth per kg of body weight. Give the child an adequate diet to prevent malnutrition, and eat whatever was originally eaten. Fasting is harmful in patients with diarrhea, and experiments have shown that most of the diet eaten can be absorbed. Monitor the condition closely. If the child’s symptoms do not improve within three days of treatment, or if any of the following symptoms appear, he or she should see a doctor Increased frequency and volume of diarrhea, frequent vomiting, marked thirst, inability to eat normally, fever, and blood in the stool. Children with acute watery stool diarrhea, mostly viral or toxigenic E. coli infections, generally do not need antibacterial drugs and can heal themselves with good oral rehydration. The use of Chinese medicine treatment, or the use of intestinal mucosa protective agents, such as Similac, can shorten the course of the disease. Children with mucus and pus and blood stools, mostly invasive bacterial infections, should be treated with effective antibacterial drugs under the guidance of a doctor. Don’t let antibacterial drugs help. Acute diarrhea is mostly viral or enterotoxin-producing bacterial infections, which do not require antibacterial drugs. Do not abuse antidiarrheal drugs, such as Emmenagogue, which are prohibited for children under 5 years old. Fluid replacement is most important. In the early stage, children can be given sugar saline or oral rehydration salts; if the diarrhea is severe, thirst is obvious and urine output is significantly reduced, you should take your child to the hospital to see a doctor.
