  • Sunken eyes or cheeks

  • Irritability

  • Rapid breathing

  • No wet diaper in 3+ hours

  • Less frequent urination

  • Dark-colored urine

  • Dizziness

  • Fatigue

  • Confusion

  • Headache

  • Feeling unusually tired or confused

  • Dizziness when standing up

  • Not passing urine for 8+ hours

  • Weak pulse

  • Rapid pulse

What causes dehydration?

The cause of dehydration can often be simple. If you are sick, busy or lack safe drinking water, you may not be drinking enough water to properly hydrate your body. Other causes of dehydration can include:

  • Vomiting and/or diarrhea

  • Fever

  • Excessive sweating

  • Increased urination

If you are unsure of the cause of your dehydration or have several other symptoms, it is best to visit an urgent care center near you so a medical provider can treat all your symptoms and determine the root cause of your illness.

How can I treat dehydration at home?

The best way to treat dehydration is to rehydrate the body and drink fluids like water, diluted fruit juice or rehydration solutions (Pedialyte). A sweet drink and salty snack can help replace lost sugar and salt in the body. Other treatment includes:

It is best to seek help from a medical professional for babies. In the meantime, give them
plenty of liquids like breast milk or formula. Oftentimes, it is better to give them smaller
amounts of fluids more often.

Give them an oral rehydration solution, like Pedialyte. Water alone may dilute the minerals
in their body, so they will need help maintaining their nutrient intake.

Seek medical attention immediately. It is not recommended to treat severe dehydration at
home.
