[Hormonal control of human hydratation status in space flight]
Abstract:
In long-lasting stay in state of weightlessness the astronaut develops a moderate hypophydratation of the organism accompanied by increase production of vasopressin. Most changes of the water-salt balance and kidney function will be fast enough normalised. The synthetic agonist of vasopressin V2-receptors proved to be able to control human hydratation status. The data obtained indicate a certain efficacy of Desmopressin thus opening prospects for development of a simple pharmacological means of prophylactics of the weightlessness effect.

Regulation of Water Intake
Primary Motives: Hunger and Thirst
Hunger arises when the brain detects changes in the body's nutrient levels, including glucose, lipids, amino acids, and hormones such as ghrelin and leptin. The hypothalamus plays a central role in hunger regulation. The lateral hypothalamus acts...
