Not passing urine for 20 hours is an early sign of dehydration, as frequent stools cause the body to lose essential water and
electrolytes. Potential underlying causes for these symptoms include viral gastroenteritis, a bacterial bowel infection, or a food intolerance. General management of this situation focuses on immediately replacing lost fluids using an Oral Rehydration Solution (ORS) given in small, frequent sips, while continuing breast milk or formula. Do not offer undiluted fruit juices or fizzy drinks, as the high
sugar content can worsen diarrhea
