Dehydration occurs when more water is lost from the body than we take in. Every day we lose water when we breathe, when when we sweat and when we go to the toilet. In a normal day, we have to drink a significant amount of water to replace this routine loss.

The signs and symptoms of dehydration will become apparent very quickly if the body’s water is not replenished. The body monitors the amount of fluid loss and the thirst mechanism alerts us that we need to drink water when our body is ‘dry’. In addition, hormones like anti-diuretic hormone (ADH) work with the kidney to limit the amount of water lost in the urine when the body needs to conserve water.<
