Body water of specific parts of the body. In humans, total body water can be estimated based on the premorbid (or ideal) body weight and correction factor. formula_1. C is a coefficient for the expected percentage of weight made up of free water. For adult, non-elderly males, C = 0.6. For adult elderly males, malnourished males, or females, C = 0.5. For adult elderly or malnourished females C = 0.45. A total body water deficit (TBWD) can then be approximated by the following formula: formula_2 Where [Na]t = target sodium concentration (usually 140 mEq/L), and [Na]m = measured sodium concentration. The resultant
