Drinks For Cancer Patients

Staying properly hydrated is important for everyone - especially those undergoing cancer treatments and radiation therapy. Side effects of radiation therapy such as diarrhea, nausea or vomiting can put you at increased risk of becoming dehydrated. Follow these tips to make sure you are getting enough fluids.

  • Aim to drink 6 to 8 cups of fluid per day
  • Keep a water bottle with you and take sips throughout the day
  • Drink liquids an hour before or after eating to avoid fullness 
  • Drink even if you are not thirsty

What counts as fluid?

Broth, carbonated beverages, fruit juices, Italian ice, Popsicles, gelatin, tea, water, nutritional supplements, children’s electrolyte drinks (such as Pedialyte), pudding and soups can all help to keep you hydrated.
