The concept of these diets has common core foundations and recommendations.

While diagnosing hyponatraemia, it is of major importance to carefully ask in the anamnesis about habits related to the amount of fluid intake and the type of consumed fluids. It should also be noted that a frequent procedure during an infection is to increase fluid ingesting as a prevention of dehydration.
