A yellow fallen leaf and a cool autumn breeze tell us that autumn is here! Poopers and mamas with babies at home should be especially careful, as the annual peak of diarrhea is approaching. There will be waves and waves of children with diarrhea in the fall, especially children aged 6 months to 2 years with a higher incidence of diarrhea. Diarrhea is common, but never trivial. Although diarrhea is common in children and most children can recover from it, parents should not take it lightly or take chances. Why do children have diarrhea? 1, the digestive system is not strong in its own defense Infants and young children, the digestive system is not mature, prone to gastrointestinal dysfunction, and the immune function of the body is lower during this period, the gastrointestinal tract defense function is poor. 2, foreign viruses bacterial invasion Viruses are the most common pathogens that cause diarrhea in infants and young children. Especially in autumn, rotavirus is like a long-dormant ghost with the sluggish autumn breeze and awakened, arrogant and rampant attack on children. Enteritis caused by rotavirus is also known as autumn diarrhea because it occurs in autumn and winter, and the pediatric clinics of major hospitals are often overcrowded when the peak of autumn diarrhea comes. In addition to rotavirus, norovirus, E. coli, Campylobacter jejuni, Aspergillus, fungi and many other pathogens can cause diarrhea in children. 3, various other factors In addition to pathogenic infections, a variety of non-infectious factors can also cause diarrhea. Improper feeding, such as premature feeding of large amounts of starchy or fatty foods, sudden changes in food varieties, sudden changes in climate, protein allergies, lactose intolerance, etc. are all causes of diarrhea in infants and children. What is the manifestation of autumn diarrhea? As the name suggests, fall diarrhea (rotavirus enteritis) occurs in the fall and winter and often causes epidemics among children. It is often accompanied by fever and other cold symptoms, such as a runny cough. The main manifestations are vomiting, diarrhea, stools like watery or egg-flake soup-like, sometimes with a little mucus, mucous membrane breakage or combined with bacterial infection may have mucous blood, ranging from a few to a dozen times a day. Usually the duration of the disease is 3-8 days, some babies may be longer.
