This information will help you follow a clear liquid diet. Keep this resource in your kitchen. It will help you see what you can and can’t eat or drink while on a clear liquid diet.

What is a clear liquid diet?

A clear liquid diet includes mostly liquids you can see through, that don’t have any solids in them. These liquids are easy to digest and help keep you hydrated.

Your healthcare provider may tell you to follow a clear liquid diet:

  • Before your surgery or procedure.
  • For your first few meals after your surgery or procedure.
  • If you have:
    • Nausea (feeling like you’re going to throw up).
    • Vomiting (throwing up).
    • Diarrhea (loose or watery bowel movements).

Only follow a clear liquid diet for as long as your healthcare provider tells you to. This will be a short period of time. Talk with your healthcare provider about why a clear liquid diet will help you.

 

While you’re following a clear liquid diet:

  • Drink at least 1 (8-ounce) cup of clear liquid every hour while you’re awake.
  • Drink different types of clear liquids. Do not just drink water, coffee, and tea.
  • Do not drink any fluids that you cannot see through, such as milk or smoothies.
  • Do not drink sugar-free liquids unless you have diabetes and your healthcare provider tells you to.
  • Do not eat any solid foods.

How to follow a clear liquid diet if you have diabetes

Ask the healthcare provider who manages your diabetes:

  • What to do while following a clear liquid diet.
  • If you need to change the dose of insulin or other diabetes medication, if you take them.
  • If you should drink sugar-free clear liquids.

Make sure to check your blood sugar level often while following a clear liquid diet. If you have questions, talk with your healthcare provider.

Examples of clear liquids

Your healthcare provider may tell you to avoid anything red, orange, or purple. This includes liquids, gelatin (Jell-O®), and hard candies. Follow their instructions. If you have questions, talk with your nurse or healthcare provider.
