What Are Clear Liquids?

By Alyssa Speicher July 17, 2017

When you’re getting a medical imaging exam, sometimes your doctor asks that you not eat or drink anything except clear liquids before the exam. But what exactly are clear liquids?


 

Your doctor or radiologist might need you to have a clear liquid diet hours or a day before your medical imaging exam. Most people think that “clear liquids” refers to water. And yes, clear liquids include plain water, but you actually have more options than that. Clear liquids can also include things like tea and coffee (without cream), popsicles (without pulp or yogurt), and cranberry juice.

“Clear” refers to the fact that the liquids do not have added substances like milk or solid foods. The reasons for the “clear liquids” restriction vary depending on what kind of test you are having. Sometimes, the restriction is there so there is nothing in your system that would interfere with any contrast agents, whereas other times it’s to prevent you from becoming nauseous.  

No matter the reason, the quality of your exam depends in part on you following the instructions provided. If you don’t follow the instructions correctly, your exam might need to be rescheduled or redone. Use this guide to help you decide what you can and cannot drink to be best prepared for your exam:
