Hypervolemia simply means too much fluid volume, not always just too much water. If it should occur as a result of too much water, ? mechanisms serve
to correct it. However, if just the volume is expanded and there is no disruption of water concentration, the correction mechanism will differ. Basically, the
expanded volume increases blood pressure and results in increased glomerular filtration in nephrons of the kidney causing increased urine output until the
volume imbalance is corrected.
