Need for the diet:
The clear liquid diet is a temporary diet that is used in several different settings:

  • Preparation for surgery and medical tests such as sigmoidoscopy, colonoscopy, and other x-rays or tests that require little food in the stomach and intestines.
  • When someone has been unable to eat any food for several days or after surgery.

The clear liquid diet helps to keep you hydrated (body fluids, salts and minerals) and helps to get the body used to food after long periods of time without food. The clear liquids diet is easy to digest and does not leave much residue in the stomach and intestines.

Important Considerations:

  • If you experience abdominal discomfort, such as cramps or pain, contact your doctor or nurse as soon as possible.
  • The clear liquids diet does not provide enough energy, protein and many other nutrients for daily use. This diet is temporary and should not be used for more than 5 days. If you are on this diet for more than 5 days, your doctor and/or dietitian will tell you which supplement to use.
  • The amount of liquid that you drink or eat on this diet may be important. If your doctor sets a limit about the amount, follow those directions carefully.

How to choose the clear liquid diet: 

Liquids that you can see through at room temperature (about 78-72º F) are considered clear liquids. This includes clear juices, broths, hard candy, ices and gelatin. The table below will help you with your choices.
