Health Center: Hydration

• It is extremely important to drink adequate fluids with illnesses such as colds, flu, fever, diarrhea, urinary tract infections, etc.

• Signs of dehydration include dry mouth; dark, concentrated and scant urine; dizziness on standing.

• If you are not able to eat much, then a substantial proportion of the fluids you drink should contain electrolytes.  Examples include non-caffeinated and non-diet sodas, apple juice, Gatorade.  There are rehydration mixes available that contain the exact balance of electrolytes that are best for the body.  You should drink at least 2-3 liters of fluid per day.
  

• Vomiting complicates hydration strategies (see below).

• If you are unable to take adequate fluids by mouth, then it may be necessary to give them through an IV.
