Blood loss can be due to: Philadelphia, Pa.: Mosby Elsevier; 2012. http://www.clinicalkey.com. Also called osmometric thirst or osmotic thirst. WebThe term hypovolemia refers collectively to two distinct disorders: (1) volume depletion, which describes the loss of sodium from the extracellular space (i.e., intravascular and interstitial fluid) that occurs during gastrointestinal hemorrhage, vomiting, diarrhea, and diuresis; and (2) dehydration, which refers to the loss of intracellular Without treatment, hypovolemia can progress to hypovolemic shock, which is a life threatening emergency.

If you lacked vasopressin, would you drink like a beaver or like a gerbil? The risk of complications increases with age, especially if other conditions have already caused organ damage such as kidney failure or a heart attack.
