Water balance
Water balance the way in which an organism maintains water in dry or hot conditions. It is often discussed in reference to plants or arthropods, which have a variety of water retention mechanisms, including a lipid waxy coating that has limited permeability.
Disorders of water balance, particularly hyponatremia from altered antidiuretic hormone (ADH) secretion, are a common post-operative complication of transsphenoidal surgery (TSS).
