Why Colonoscopy?

For most people at average risk of developing colon cancer, screening starts at age 45.

There are multiple screening options available, including stool tests y blood tests, but colonoscopy is still considered the “gold standard” screening test because of its effectiveness and efficiency in cancer prevention.

In order for a colonoscopy to be effective, the physician must be able to get a thorough view of your colon, and in order for that to happen, you need to prepare your bowel beforehand.

Prep is often the most dreaded part of a colonoscopy, but it doesn’t need to be a cause of anxiety. We’ve put together information on the most common bowel prep methods below, along with some helpful tips.

Prep Instructions

In many cases, when your physician orders a colonoscopy, they’ll also write you a prescription for their preferred prep method. Most bowel preps require a prescription. While all prescription bowel preps come with instructions, your doctor will likely have their own set of instructions.

In general, bowel prep begins the day before a colonoscopy and ends when you complete your colonoscopy:

  • Fasting the day before the colonoscopy
  • Begin taking the bowel pre in the afternoon
  • Split-dose methods may be offered if your colonoscopy is scheduled for the afternoon.
  • Split-dose means you may take the last of the bowel prep the morning of your colonoscopy.

A few essential steps:

  • Order ahead – don’t wait until the day before your colonoscopy to pick it up. Sometimes pharmacies don’t have the bowel prep you need in stock, and they will need to order it – which can take a few days.
  • Stay in communication with your doctor’s office. If you’re sick, if you don’t think it’s working, or if you need an alternative, let your doctor know.
  • Complete all of the prep. If you don’t drink everything (or take all of the pills), your colonoscopy may be ineffective, and you may even have to reschedule (and repeat the prep!)

Split Dosing

A “split-dose” regimen uses the same volume of bowel prep but splits the dosage in two: one dose in the evening, and one dose in the morning of your procedure date. Split dosing may be easier to tolerate for some people and has been shown to be an effective method of bowel prep administration.

All of the bowel prep options include instructions for a split-dose regimen. If you are interested in splitting your prep dose, discuss this with your physician so you can schedule your colonoscopy for an appropriate time and receive clear instructions on how to take your prep.

A split-dose regimen typically follows these instructions:

  • Do not consume the entire bowel cleansing agent at once or on the same day.
  • Take half the total dose of the bowel cleansing agent the evening before your colonoscopy. This is usually between 5:00-7:00 PM.
  • Continue to consume clear liquid diet after the first dose of the bowel cleansing agent.
  • Take the second half of your bowel cleansing agent on the day of your colonoscopy, about 4-5 hours before your scheduled colonoscopy.
  • Do not consume anything at least 2 hours before your colonoscopy.

Instead of writing you a prescription for prep, your doctor may advise you to use an over-the-counter (OTC) alternative. OTC methods can provide satisfactory prep results, but it is important that you follow the instructions provided to you closely.

Are you on a GLP-1?

Many patients are currently on a GLP-1 for type 2 diabetes management and/or weight loss. These drugs may slow down your digestion, and could impact your colonoscopy prep.

If you have scheduled a colonoscopy, make sure to notify your doctor if you’re on a GLP-1 so you can discuss altering the prep instructions so you get an adequate prep.

Prep Diets

As part of the prep process, you’ll be required to adhere to a specific diet to minimize residue in your colon. Your physician will tell you exactly what you need to do, but generally, you’ll be asked to maintain a low fiber/low residue diet in the days leading up to your colonoscopy, and a clear liquid diet the day before and day of the actual procedure.

Maintaining this diet is critical to the success of your colonoscopy prep. If you are unable to sufficiently cleanse and flush your colon, you’ll likely be required to reschedule your procedure and repeat the entire prep process, adding time and inconvenience to an already somewhat inconvenient process.

Clear Liquid Diet

Many prep methods require you to maintain a clear liquid diet the day before (and day of) your colonoscopy. This helps the prep work more effectively and ensures that your colon is clean and ready for the procedure.

A clear liquid diet excludes red and purple colored substances, and excludes alcohol. Examples of clear liquid diet include water, tea, plain coffee, lemonade from powdered mix, carbonated beverages and soda, clear juices such as apple and white grape, plain or flavored gelatin, sports drinks such as Gatorade® , All-Sports®, Powerade®; sorbet, popsicles, honey, sugar, hard candy, fat-free broth, bouillon or consommé.

Low Fiber/Low Residue Diet

Your doctor may also recommend that you follow a low fiber/low residue diet for several days leading up to your colonoscopy, with a clear liquid diet the day before.

Or, new 2025 guidance has suggested that eating a low-residue diet the day before a colonoscopy may be permissible. Read more in our blog: What Can I Eat the Day Before a Colonoscopy?

Low residue refers to undigested food or fibers that make up part of the stool. A low residue diet reduces the frequency and volume of stool while prolonging the time it takes food to travel the intestine.

You should avoid the following food items: whole wheat breads, cereals, crackers and rolls; whole wheat pasta, brown or wild rice; any item with nuts, seeds and fruits; buckwheat, granola, cornbread, pumpernickel bread; tough meat and meat items with skin; raw fruits, prunes and prune juice, berries, raisins and dried fruits; raw or partially cooked vegetables. You should also avoid milk and milk products.

If you are on a low residue diet, you may be allowed to have white bread, rolls and biscuits; white rice or noodles; plain crackers, potato rolls, skinless cooked potato; skinless chicken, skinless turkey, fish and other sea food; canned fruits without seeds or skin; eggs; vanilla wafers.

How do I know if my prep worked?

Great question! You’ve likely been spending a lot of time on the toilet during your prep process, so it’s natural to wonder if you’ve done everything correctly. Your last stool after finishing your prep agent can act as a guide.

Your stool should be clear, yellow, light, and fully liquid. The presence of dark particles or thick brown stool means that you are not yet ready for your colonoscopy.

If you are still having solid or dark stools on the morning of your scheduled procedure, reach out to your doctor’s office for advice on how to proceed.

Look for these three signs to know you’re ready for your colonoscopy:

  • Your stool is clear yellow liquid without dark particles
  • Your stool comes out like an open tap
  • You feel like having a bowel movement, but nothing comes out

How do I know if my prep worked?

What happens after my colonoscopy?

After a colonoscopy, some patients are in “the clear” and do not need to return for another colonoscopy for 10 years. If a polyp or abnormality was found, or if you are not average-risk for colorectal cancer, you will need to repeat a colonoscopy sooner.

Talk to your doctor about the best screening interval for you. And whatever you do, go have a great meal. You earned it!
