Gorączka, wymioty, silna biegunka, nadużywanie leków moczopędnych i intensywny wysiłek fizyczny mogą prowadzić do odwodnienia, potencjalnie poważnego stanu, w którym organizm traci więcej wody niż przyjmuje. Nawet łagodne odwodnienie (utrata zaledwie 1 do 2 procent masy ciała) może powodować osłabienie, zawroty głowy i zmęczenie.
