Can you drink cola before a colonoscopy?

It is generally recommended to avoid drinking cola or other carbonated beverages before a colonoscopy. This is because carbonated beverages can cause gas and bloating, which can make it more difficult for the doctor to perform the procedure. Additionally, the sugar content in cola can interfere with the accuracy of the colonoscopy results.

Instead of cola, it is recommended to drink clear liquids, such as water, broth, and tea, before a colonoscopy. These liquids will not cause gas and bloating, and they will help to keep you hydrated.
