Baby diarrhea needs to be treated according to its etiology, so the choice of medication also needs to be based on the etiology. If the diarrhea is caused by an infection, antibacterial and antiviral treatment is recommended, and antibacterial and antiviral drugs can be given appropriately. For non-infectious diarrhea, you can take montelukast, which has an astringent effect to stop diarrhea, and you can also add appropriate Chinese medicine to strengthen the spleen and stomach under the guidance of the doctor, which will help the recovery of diarrhea. In addition, you can also try to supplement your baby with probiotics, including Bifidobacterium bifidum live bacteria preparations, Lactobacillus live bacteria preparations, such as Mamia, for indigestion, loss of appetite, malnutrition, intestinal flora disorders caused by diarrhea, constipation, abdominal distension and other conditions. If bifidobacterium is not working well, you can also take quadruple bacterium, which can balance the microbial environment of the intestine more effectively. In addition, the baby’s diarrhea also needs to be ruled out if it is due to lactose intolerance. If a formula-fed baby is lactose intolerant, switch to a lactose-free formula. Also pay attention to giving your baby salt hydration to avoid dehydration. Pay attention to giving your baby fresh food, not to eat overnight leftovers, and not to eat cold and spicy stimulating food to prevent discomfort such as nausea, vomiting, bloating, diarrhea and abdominal pain, which can affect your baby’s normal growth and development.
