In most cases of non-infectious diarrhea, the symptoms of diarrhea disappear quickly after drinking more water and adjusting the diet. However, the most worrying thing for parents during the course of diarrhea is dehydration. The ratio of salt to water in a baby’s body is balanced, and a healthy gut and kidneys ensure this balance and allow the body’s organs to function properly. Diarrhea disrupts this balance, causing the body to lose water and salt, which is known as dehydration. If you add vomiting to the mix, then your baby is even more susceptible to dehydration. Symptoms of dehydration: (1) Mild dehydration: water loss is 5% of body weight (50ml/kg). The child’s spirit is slightly poor, the mucous membrane of the mouth and lips is slightly dry, there is a slight sense of thirst, the eye sockets and fontanel are slightly sunken, there are tears when he cries, the skin elasticity is normal, and the amount of urine is slightly reduced. (2) Moderate dehydration: water loss is 5% to 10% of body weight (50-100ml/kg). The child is depressed or irritable, the mucous membrane of the mouth and lips is dry, the eye sockets and fontanel are obviously sunken, there are few tears when crying, the skin elasticity is poor, the urine output is obviously reduced, and the limbs are slightly cold. (3) Severe dehydration: water loss is more than 10% of body weight (100-120ml/kg). Extreme mental depression, indifferent expression, extremely dry mucous membrane of mouth and lips, deep depression of eye sockets and fontanel, no tears when crying, poor skin elasticity, little or no urine output, symptoms of shock, cold extremities and decreased blood pressure.
