About this calculator
The Water Deficit Calculator is a useful tool for healthcare professionals, especially in Endocrinology, who want to calculate the water deficit in patients with hypernatremia.
The calculation is based on the formula TBW·((Na/140) − 1), where TBW is the total body water and Na is the blood sodium level. This allows healthcare professionals to have a precise idea of the water deficit in each patient.
It is essential to use this calculator in cases of hypernatremia, when the blood sodium level is above normal. This can be caused by several conditions, including excessive water loss through urine, consumption of isotonic beverages or excessive sweating.
Before using this calculator, it is essential to remember that patients with hypernatremia need to be carefully evaluated and treated by qualified healthcare professionals.
