Diarrhea is a common disease among children in the fall and winter, and its causes are complex, which can be summarized as “illness by mouth”. The pathogen causing diarrhea is mostly rotavirus, and the stools are mostly watery or egg-like stools with a fishy odor. Regardless of the results of the stool test, the treatment method is similar. Simply put, there are three tricks: eat thin rice, drink salt water, take live bacteria. 1, eat thin rice to control the diet. If the digestive tract disease if you control the diet can control half of the disease. Vomiting children must be fasted, do not feed within 6 hours; 6 hours after not vomiting best to feed some thin rice or rice soup or the like, this time if still keep eating, it will cause very serious consequences. The natural course of diarrhea is usually one week, and “starvation therapy” is the fastest way to recover from the disease within a week. Do not try to enhance nutrition at this time, as the digestion and absorption of any food nutrients will increase the “work” of the gastrointestinal tract. It’s like lifting a heavy object with a broken arm, which is not conducive to intestinal recovery. Simply put, if you eat more, you will have more diarrhea, even to the point of having blood in your stool. Some parents of children with diarrhea consult whether they can drink milk powder, in fact, it is not necessary, and then resume normal diet when the disease is well. 2, drink salt water. The salt water here is not our daily edible salt solution, but the prescription oral rehydration salt prescribed by the World Health Organization, the first generation is very astringent, but now the third generation has a very good taste. Do not use antibiotics or too many other medications. There are many diarrhea treatment drugs, and too many of them cannot shorten the course of the disease, but rather aggravate it, turning acute diarrhea into prolonged or chronic diarrhea in many children, increasing the difficulty of parental care and the degree of resistance of the child. At this time, only a large amount of oral rehydration salts are needed, with no requirement for the number of times and no dosage limit, the standard being the increase in urine and tears of the child. Children’s urine and tears are generally safer. 3. Take live bacteria. The only oral drug to be recommended is the micro-ecological preparations, that is, parents know the live bacteria preparations. The amount of general reference to the instructions on the dose of adults, the amount of less effective. This drug generally has no side effects, take to the child stool back to normal, and then continue for a few days.
