Tea Before Colonoscopy

When it comes to tea:

Remember to abstain from adding any milk, cream, or non-dairy creamers as these are not part of a clear liquid diet. This preparation is critical for the success of your colonoscopy, as a clean colon allows your doctor to observe the lining without obstructions.

Types of Tea Permissible Before Colonoscopy

Ahead of a colonoscopy, it's crucial to stick to clear or light-colored teas that are free of additives.

Herbal Teas

  • Peppermint Tea: Completely clear and free of any additives.
  • Lemon Verbena: Must be strained well to ensure no leaves or residue.

Note: Avoid any herbal teas with red, purple, or blue coloring as they can potentially mimic blood in the colon.

Clear Teas

  • White Tea: Pure and light in color, without milk or cream.
  • Green Tea: Ensure it's not too concentrated; a lighter brew is preferable.

Remember, the tea you choose should be free of pulp, leaves, or thick agents that are not easily strained.

Teas to Avoid Prior to Colonoscopy

Black and Green Teas:

  • Traditional black tea and green tea are typically safe if they're unflavored, but you must ensure they're not strongly colored.
  • Milk or cream should not be added to any tea, as dairy can interfere with the cleanliness of the colon.

Timing for Consuming Tea Before Colonoscopy

When preparing for a colonoscopy, the timing of what you consume is crucial. You'll need to switch to clear liquids, which may include some types of tea, the day before your procedure. Your doctor will provide exact instructions, but typically, the timeline looks like this:

The Day Before Your Colonoscopy:

  • Morning to Early Afternoon: You may drink light-colored teas, such as white, green, or yellow tea.

  • Up to Midnight: You can continue drinking clear liquids, including the allowed teas.
