Why do children have diarrhea?

Diarrhea diseases are quite common in life. Many children will have diarrhea symptoms and be harmed by diarrhea. At present, it seems that there are many reasons that can cause diarrhea in children. We must attach importance to this disease in life and pay attention to the cause of the disease. What factors can cause diarrhea in children?

Causes of diarrhea in children:

(1) Infection in the digestive tract: Pathogenic microorganisms can enter the digestive tract of children through contaminated food or water, and are therefore prone to occur in artificially fed children. If the utensils or food used for feeding are not disinfected or are not disinfected enough, infection is also possible. Viruses can also be transmitted through the respiratory tract or water sources. The second is infection by adult carriers of bacteria (viruses). For example, after an outbreak of bacterial (or viral) enteritis in a ward, some medical staff are infected and become asymptomatic intestinal carriers of bacteria (viruses), which can lead to the spread of pathogens.

(2) Extra-digestive tract infection: Infection of organs and tissues outside the digestive tract can also cause diarrhea, which is common in otitis media, pharyngitis, pneumonia, urinary tract infection and skin infection. Diarrhea is usually not serious and is more common in younger people. The cause of diarrhea is partly due to extra-intestinal infection causing digestive dysfunction, and partly due to infection of the same pathogen (mainly viruses) inside and outside the intestine.

(3) Intestinal flora disturbance caused by the abuse of antibiotics: Long-term and large-scale use of broad-spectrum antibiotics such as chloramphenicol, kanamycin, gentamicin, ampicillin, and various cephalosporins, especially when two or more are used together, can directly stimulate the intestines or stimulate the autonomic nerves to cause increased intestinal motility, reduced glucose absorption, and reduced disaccharidase activity, resulting in diarrhea. More seriously, it can cause intestinal flora disturbance. At this time, normal intestinal Escherichia coli disappears or significantly decreases, while drug-resistant Staphylococcus aureus, Proteus, Pseudomonas aeruginosa, Clostridium difficile, or Candida albicans can multiply in large numbers, causing enteritis that is difficult to control with drugs.
