Totale Liggaamswater-sakrekenaar
Water is die grootste enkele komponent van die menslike liggaam. Hierdie sakrekenaar skat jou totale liggaamswater (TBW) in liter en as 'n persentasie van liggaamsgewig met die gevalideerde Watson-formule, wat ouderdom, geslag, lengte en gewig gebruik. TBW is tipies ongeveer 50–65% van liggaamsgewig — hoër by mans en by maerder mense, en laer wanneer liggaamsvet hoër is omdat vet min water hou. Dit word in voeding, nierversorging en vloeistofbestuur as 'n basislynverwysing gebruik.
Skatting met die Watson-formule. Totale liggaamswater is tipies ongeveer 50–65% van liggaamsgewig (hoër by mans en maerder mense, laer met meer liggaamsvet). Hidrasiebehoeftes en kliniese gebruik moet met 'n professionele persoon bevestig word.
Gereelde Vrae
- What is total body water and why does it matter?
- Total body water (TBW) is the total volume of fluid in your body, both inside and outside your cells. It's central to circulation, temperature control and nutrient transport, and typically makes up a little over half of adult body weight.
- How is total body water calculated?
- This calculator uses the Watson formula, which estimates TBW in litres from your age, sex, height and weight using sex-specific equations. Enter those four values and it returns your estimated litres of body water and that water as a percentage of body weight.
- What percentage of body weight should be water?
- Total body water is generally around 50–65% of body weight, typically near 50–55% for women and 55–65% for men, declining with age and higher body fat. Leaner, more muscular bodies hold a higher water percentage since muscle is water-rich.
