Can You Drink Tea Before a Colonoscopy?

The short answer to this commonly asked question is yes, but there are conditions attached.

Before a colonoscopy, preparing your bowel for the procedure is essential. This is achieved by undergoing strict diets in the days preceding the colonoscopy. These diets are the Low-fiber diet and the clear liquid diet. On both diets, you can drink tea. However, on the clear liquid diet (which is the stricter diet), only clear tea is allowed. This means you cannot add milk, creamer, or other opacity-inducing additives to your tea on a clear liquid diet.

When Tea May Not Be Allowed

While tea is generally permissible before a colonoscopy, there are some instances when drinking certain types of tea is not allowed. Some examples include:

Tea with Dairy: Tea containing milk or milky products is impermissible on a clear liquid diet. The milk changes the tea’s clear state, and opaque liquids are not allowed before a colonoscopy.

Artificial Coloring: Before a colonoscopy, it is advisable to avoid artificial coloring, specifically red, blue, and purple. These colors can stain the colon’s lining and be mistaken for pathological signs.

Solid Particles: Some herbal teas contain solid—mostly leafy—particles, which makes them unsuitable for drinking on a clear liquid diet.
