This recommendation was based on multiple clinical trials showing that the reduced osmolarity solution reduces stool volume in children with diarrhea by about twenty-five percent and the need for IV therapy by about thirty percent when compared to standard oral rehydration solution. The incidence of vomiting is also reduced.
Partial fluid restriction can be used as therapy, but has the disadvantages of being difficult to maintain, and it is often ineffective. [6] Drugs causing increased diuresis is generally an alternative, and have less risk of causing decreased glomerular filtration rate through the kidneys and resultant decreased kidney function.
