Hypo-Aldosterone

Aldosterone when it's released plays an important role at the kidneys to reabsorb sodium back into the body. So we're losing more sodium than water, even though water is being lost. We also get a more significant loss of solute in the extracellular fluid. But because the water's been dragged into the cell, the cell's going to become over-hydrated, but also hypo-osmodic as well.
