Can you drink mountain dew before colonoscopy?

Are you planning on having a colonoscopy soon, and are wondering if you can drink Mountain Dew beforehand? Well, you’ve come to the right place, because we’re about to answer that question for you!

Firstly, let’s discuss what a colonoscopy is.

What Is A Colonoscopy?

A colonoscopy is a medical procedure used to diagnose and treat conditions within the large intestine. During this procedure, your doctor inserts a thin tube with a camera attached into your rectum and advances it slowly through your entire colon. This allows them to view any abnormalities or issues along the way. It’s recommended that everyone over 50 years old has regular colonoscopies as part of preventative healthcare.

Now that we know what it is, let’s get back to our original question: “Can you drink Mountain Dew before a colonoscopy?” The simple answer is..


Under no circumstances should you consume carbonated drinks such as soda pop before undergoing this important medical procedure – especially not something like Mountain Dew which contains high amounts of sugar and caffeine. Consuming these types of beverages can cause several issues:

  1. Carbonation – drinking carbonated beverages produces gas in your stomach which will not only increase discomfort but makes inserting the endoscope more difficult.
  2. Sugar overload – sugary drinks such as Mountain Dew will leave remnants in your bowel after consumption and interfere with proper bowel preparation processes.
  3. Insomnia – caffeine found in sodas would stimulate an individual leaving him/her feeling restless thereby disrupting their sleep patterns making subsequent treatment procedures highly uncomfortable.

Prepping For Your Colonoscopy

Before undergoing any kind of visual examination of bowels/digestive tract or even minimally invasive procedures like colonoscopy, there are strict instructions on the foods and liquids you should consume prior to the examination. It would be in your best interest to avoid drinks altogether especially sugary, carbonated drinks such as Mountain Dew.

Why Can’t You Drink Before A Colonoscopy?

When preparing for a colonoscopy, you cannot eat anything solid, except clear broth or gelatin without fruit or toppings unless deemed otherwise by medical expert- at least 24 hours before starting preparation process.
Drinks restricted include any with red dye because they can mimic blood within intestines so no cranberry juice whatsoever! Do not drink/yogurt containing any lactic acid bacteria like orange juice. This specific bacterium fights against preventative medicine solutions that must coincide with preoperative preparations.
Most importantly when asked about drinking beverages – stick strictly to plain water .

It is vital that the bowel is clean of solids and liquids during prep time – which usually begins a few days beforehand – in order for doctors to obtain accurate readings during the procedure as well as visualizing possible abnormalities along whole digestive tract under lens. Drinking of soda pop will interfere with this entire process resulting in increased gasses present creating additional discomforts while performing subsequent operations including surgical ones

What Should You Drink Instead?

During your preparation process prior to undergoing a colonoscopy it’s essential that you remain hydrated so ensuring maximum digestion ease later doesn’t seem impossible! Ensure you’re only taking clear fluids within period leading up until appointment time –

Some things to consider:

1) Clear Broth/ Soup
2) Water (However much required)
3) Green Tea- Avoid sweeteners. Wake-up flavors further disrupt sleep routines necessary after consumption of tea leaves infused into hot liquid.
4) Fruit juices i.e apple,citrus or white grape lacking pulp — eating fats triggers excess bile production making interpretation afterwards more difficult than it already was supposed too hence why everyone recommends sticking strictly to fluids clear in color relative to their source.

You may also be given a laxative or bowel cleanse between one and three days before your colonoscopy which removes any stool remaining within the bowels, so drinking plenty of fluid is recommended during this time. It’s advisable not have electrolyte drinks/ other sport-based drinks -just as you shouldn’t with Mountain Dew- if doing this directed by physician then asking what should be drunk pre-examination will provide better guidance.


In conclusion, do not drink Mountain Dew before a colonoscopy, it (and any other sugary/carbonated beverages) interferes with processing procedures before undergoing examination.
It’s important that you prepare for your colonoscopy properly, and follow any specific instructions given by your doctor or gastroenterology team. By staying hydrated with water or suggested liquids listed above beforehand while having done sufficient prep works required and don’t leave it up to chance especially if just had a can of mountain dew recently!
