Inability to urinate / dark urine
The kidneys need water to function properly and remove toxins from the body. If you don’t drink enough water, your kidneys will retain more water and produce less urine. In addition, the next time you urinate, it will be more toxic, darker in color and more smelly.
Constant hunger and strong cravings for sweets
Without enough water, the body will have difficulty releasing energy from glucose stores. As a result, you are hungry and crave for sweet foods like chocolates, cakes and sweets. If this happens, meaning you are still hungry after eating, it may be a sign of dehydration.
