Mild to moderate dehydration

Symptoms of mild dehydration include:

  • You are more thirsty than usual.
  • Your urine is darker than usual.

Symptoms of moderate dehydration include:

  • You are a lot more thirsty than usual.
  • Your mouth and eyes are drier than usual.
  • Your urine is much darker than usual.
  • You pass little or no urine for 8 or more hours.
  • You feel dizzy when you stand or sit up.

Whenever you have an illness that causes a high fever, vomiting, or diarrhea, your chance of dehydration increases because your body is losing water more quickly than you can replace it. This is especially true if you are vomiting and are unable to replace lost fluids.

Babies, small children, and older adults cannot replace lost fluids as efficiently as older children and young adults. They should be watched closely for signs of dehydration when they become ill.
