Dehydration occurs when the loss of water and minerals is not compensated by adequate external inputs. Although the human body contains about 60 per cent of water, it regularly releases water through urine, breathing and sweat. 2 per cent loss of water is considered moderate dehydration and 10 per cent loss of water.

There are two types of dehydration:

  • Subcellular dehydration: Sodium loss results in proportional loss of water. Intracellular dehydration: leakage of water from the cell to the extracellular sector. To restore osmotic balance, intracellular fluid flows into the extracellular environment.

Dehydration is most often global and includes both of the above types of dehydration.

Causes of dehydration

  • Excessive sweating due to long loads or severe heat

Initial signs of dehydration

  • The thirst for the lips and the throat is tired. Loss of concentration.

Severe dehydration

  • Loss of weight Low blood pressure Deteriorated eyes and fallen eyelids

What do you do when dehydrated?

  • Cool a man with wet tissue. Let him drink something, especially drinks containing sugar and mineral salts. Heavy dehydration is treated in a hospital by injecting water with glucose and adding mineral salts.
