Determine the Fluids and Electrolyte Requirement at high Altitude?

In addition to cold induced diuresis, hyperventilation together with a dry environment at HA makes an individual prone to hypohydration. Acute exposure to inoderate altitude causes transient hypohydration, which is due to an increased diuresis and reduction in thirst perception. Prolonged stay at extreme altitudes may cause severe salt and water retention. The role of hormones in normal fluid metabolism at high altitude is not clear, but a number of hormones play a role in retention of salt and water in pathologic states like acute and sub-acute mountain sickness.
