The Hard Truth: Solid Food is Forbidden
It is a common and critical misconception that you can consume solid food, or anything you want, while taking Nulytely. Nulytely is a powerful osmotic laxative designed to empty your digestive system completely. Consuming any solid food, milk, or other non-clear liquids during the critical preparation phase can compromise the effectiveness of the bowel prep, leading to a poorly cleansed colon. A poorly prepped colon may result in an inaccurate diagnosis, missed polyps, and could force your doctor to reschedule the procedure.
The Dietary Timeline Before Nulytely
Proper preparation for a colonoscopy with Nulytely begins well before you start drinking the solution. Following a tiered dietary plan is key to setting yourself up for success.
Days Before: Low-Fiber/Low-Residue Diet
Starting several days before your procedure—typically 3 to 5 days, depending on your doctor's instructions—you must switch to a low-fiber, low-residue diet. This helps reduce the amount of indigestible material in your system, making the final flush more effective. Low-residue foods are those that leave minimal stool in the colon after digestion.
Here are some examples of what to eat and what to avoid during this phase:
Allowed low-fiber foods:
- Lean meats, like chicken, fish, and eggs
- White bread, white rice, and plain crackers
- Ripe bananas and canned or cooked fruit without skin or seeds
- Well-cooked vegetables without skin or seeds, like peeled potatoes or carrots
- Broth, bouillon, or strained soups
- Plain pasta or noodles
Foods to avoid (high-fiber/high-residue):
- Nuts, seeds, and popcorn
- Whole grains, brown rice, and cereals with high fiber content
- Raw fruits and vegetables, especially with skins or seeds
- Legumes, including beans and peas
- Fatty or fried foods
- Tough meat with gristle
The Day Before: The Clear Liquid Diet
The day before your colonoscopy is when the diet becomes most restrictive. You must switch entirely to a clear liquid diet and cease all solid food intake. This means consuming only liquids that are transparent and have no pulp or solid bits. It is also important to avoid anything with red or purple dye, as these can be mistaken for blood in the colon.
The Crucial Clear Liquid Diet
This part of the preparation requires strict discipline. While it is challenging, remembering that it is temporary for a more accurate result can help.
Allowed Clear Liquids
- Water
- Clear broth (chicken, beef, or vegetable)
- Strained, pulp-free juices (like apple or white grape)
- Sports drinks (light-colored, like yellow or green Gatorade)
- Plain gelatin or popsicles (yellow, green, or orange)
- Black coffee or tea (no milk or cream)
- Clear sodas (Sprite, 7-Up, ginger ale)
- Hard candies (lemon or other light flavors)
Prohibited Items
- Solid Food: No exceptions.
- Milk or Dairy Products: This includes milk, cream, and non-dairy alternatives.
- Juices with Pulp: Orange juice, grapefruit juice, and prune juice.
- Alcohol: Avoid completely.
- Anything with Red or Purple Dye: Gelatin, sports drinks, or candies.
- Nutritional Supplements: Such as Ensure or Boost.
Understanding the "Why" Behind the Restrictions
The purpose of Nulytely is to clean out your colon completely for your doctor to get a clear view of the lining. The preparation is effective only if there are no solid remnants blocking the view. The low-fiber diet reduces the amount of indigestible material, and the subsequent clear liquid diet prevents new material from entering the colon. Failure to follow this process risks an inadequate cleanout, potentially requiring a repeat procedure.
How to Make the Clear Liquid Diet Tolerable
- Chill the prep solution: Many find Nulytely easier to drink when it is very cold.
- Use a straw: Drinking the solution through a straw can help bypass some of your taste buds.
- Add flavoring: If your prep doesn't include a flavor packet, you can add a clear, light-colored flavor mix, such as lemonade Crystal Light, but avoid red or purple.
- Suck on hard candies: Sucking on hard candies (not red or purple) can help with the taste and keep your mouth busy.
- Stay busy: Distract yourself with books, movies, or other activities to take your mind off of hunger.
What to Expect While Taking Nulytely
As the name suggests, this preparation is intense. You should expect frequent and watery bowel movements within a few hours of starting the solution. This is the expected effect and indicates the prep is working. Other common side effects include nausea, bloating, and abdominal cramping. If nausea or discomfort becomes severe, your doctor may advise you to slow down your drinking pace. For rectal irritation from frequent trips to the bathroom, using a soft cloth and a protective ointment can provide comfort.
Allowed vs. Forbidden: A Quick-Reference Table
| Item | Low-Fiber Phase (Days Before) | Clear Liquid Phase (Day Before) |
|---|---|---|
| Solid Food | Yes (Low-fiber only) | No |
| Clear Broth | Yes | Yes |
| Pulp-free Juice | Yes | Yes |
| Milk/Dairy | Yes (in moderation) | No |
| Whole Grains | No | No |
| Nuts/Seeds | No | No |
| Red/Purple Dyes | Avoid | No |
| Alcohol | Yes (in moderation) | No |
Conclusion: Patience for a Clear Result
To answer the question, "Can I eat anything while taking Nulytely?" the answer is an emphatic 'no' for the day leading up to the procedure, and a very limited 'yes' for the preceding days. By adhering strictly to the low-fiber and clear liquid diet guidelines provided by your doctor, you ensure the most accurate and effective result from your colonoscopy. The dietary restrictions are temporary, and following them precisely prevents the inconvenience and risk of having to repeat the procedure.
