  • feeling thirsty and lightheaded
  • dry mouth
  • tiredness
  • having dark coloured, strong-smelling urine
  • passing urine less often than usual

  • babies and infants – they have a low body weight and are sensitive to even small amounts of fluid loss
  • older people – they may be less aware that they are becoming dehydrated and need to keep drinking fluids
  • people with a long-term health condition – such as diabetes or alcoholism
