Diarrhea is a very common symptom in children. Many parents are at a loss as to how to properly medicate their children when faced with diarrhea, and even if the doctor prescribes medication, the wrong way to feed the medication does not have the desired effect. What is the right way to eat? The following is based on the different causes of diarrhea, the introduction of commonly used drugs and the correct method of feeding. 1, pediatric enteritis pediatric enteritis is the most common cause of diarrhea in infants and children. Most enteritis in children is caused by viruses, such as rotavirus, adenovirus, norovirus, etc. The typical manifestations of viral enteritis are: vomiting followed by diarrhea, dilute watery stools, watery stool separation, generally more frequent and more volume of stool each time, some children will have fever, and severe cases will show symptoms of dehydration, such as reduced urine output, depression, less tears when crying, and loss of appetite. The most common drugs used for enteritis: montmorillonite (to stop diarrhea, lock the role of water in the intestinal tract, can effectively reduce the number of stools and water loss, each packet of about 50 ml of warm water, not too dilute or too thick); oral rehydration salt (for enteritis with mild to moderate dehydration, effective replenishment of water, relieve dehydration symptoms, preferred oral rehydration salt III, when taking strictly in proportion to the preparation); probiotics (to regulate the role of intestinal (There are many kinds of probiotics on the market, so it is recommended to buy them from regular pharmacies or hospitals and eat them according to the instructions); it should be emphasized that children with viral enteritis should be fed more intensively, not because the child does not eat, otherwise it may aggravate the symptoms of dehydration, and also pay attention to zinc supplementation, which can shorten the course of the disease. It is important to note that antibiotics must not be used casually, otherwise it will aggravate the intestinal flora dysbiosis, unless there is clear evidence to confirm that the child is bacterial enteritis, only under the guidance of a doctor can apply antibiotics. 2, lactose intolerance The typical symptoms of lactose intolerant children are: frothy stools, sour smelling stools, accompanied by bloating, vomiting, poor appetite and other symptoms. Lactose intolerance is due to the lack of lactase, and there are two ways to treat it: one is to use lactose-free formula, and the other is to take lactase orally. Personally, I recommend the latter, i.e. taking lactase orally before each milk intake. Milk protein allergy children with milk protein allergy usually have thin stools, more blood in the stool, and some children have eczema, which even affects their growth and development. Milk protein allergy requires a protein avoidance diet, and there are two methods: 1. For exclusively breastfed children, the mother should avoid eating milk, eggs, nuts, beans, wheat, seafood, etc. for two weeks; 2. If the child is eating milk powder, it is recommended to switch to deeply hydrolyzed milk powder or amino acid milk powder and observe for 2 weeks. During the observation period, if the diarrhea is relieved and the blood is reduced, that means the child is allergic to milk protein, continue to avoid eating or hydrolyzed milk powder for 3-4 months, after the symptoms are stabilized, slowly add diet or switch to milk. 4, simple indigestion This situation is generally good mental state of the child, normal weight gain, knowledge of the stool frequency slightly increased, no blood, mucus, generally only oral probiotics can be.
