Laxatives And Endoscopy: Necessary Prep Or Unnecessary Hassle?

Preparing for an endoscopy involves taking laxatives to ensure the success of the procedure. Laxatives are used to clean out the bowels, allowing the doctor to see inside the colon clearly. This is crucial for detecting signs of colorectal cancer, such as polyps, which often cling to the inside walls of the colon. The type of laxative formula and the timing of ingestion depend on the patient's personal sensitivities and their healthcare provider's recommendations. It is important to follow the instructions provided by medical professionals to ensure the effectiveness of the procedure and avoid rescheduling.

What to eat and drink before an endoscopy

Preparing your body for an endoscopy requires a few days of dietary changes. Here is a detailed breakdown of what to eat and drink before the procedure:

One Week Before the Procedure:

It is recommended to stop taking any iron supplements. Iron can interfere with the endoscopy, so it is important to discontinue its use at least one week in advance.

Three Days Before the Procedure:

Discontinue the use of Vitamin E, ibuprofen, and similar medications. These substances can have an impact on your body that may affect the endoscopy results. If your physician approves, you may also stop taking blood thinners such as Coumadin, Warfarin, or Plavix. It is important to consult your doctor before making any changes to your medication.

The Day Before the Procedure:

On this day, it is crucial to follow a clear liquid diet. This means you can consume clear liquids such as apple juice, Sprite, ginger ale, tea, coffee (without milk), and broth. Solid foods, milk, and milk products are not allowed. It is important to note that red or purple liquids should also be avoided. In the evening, at 6 pm, drink a laxative as directed by your physician. This will help clear your bowels. Continue with the clear liquid diet throughout the evening to stay hydrated.

The Day of the Procedure:

On the day of your endoscopy, you should not consume anything else except for approved medications, which you can take with a small sip of water. It is important to follow the instructions provided by your physician regarding the timing of your last meal and any specific dietary restrictions.

Remember, it is always best to consult your healthcare provider for personalized instructions and to address any questions or concerns you may have about the procedure.

When to take laxatives

The timing of when to take laxatives depends on the type of laxative formula you are using and the time of your procedure. Laxatives are typically taken the day before your procedure, but in some cases, you may need to start taking them several days in advance.

For example, if you are using a PEG-based laxative formula, you will typically need to start taking it the afternoon or evening before your colonoscopy. This type of laxative usually comes in powder form and needs to be mixed with a large volume of water. It is important to follow the schedule in your bowel preparation packet carefully, as inadequate preparation may result in your procedure being postponed, cancelled, or repeated.

On the other hand, if you are using a sodium phosphate (NaP)-based laxative, you may be able to take it in tablet form. These formulas are often taken the day before the procedure, but the exact timing will depend on the specific formula and the time of your colonoscopy.

In some cases, you may need to take additional steps, such as an enema or a second dose of the laxative, if your bowel movements are not progressing as expected. It is important to follow the instructions provided by your healthcare provider and to contact them if you have any questions or concerns.

Additionally, it is recommended to make dietary changes several days before your procedure. This includes eating a low-fibre diet for two to three days, followed by a clear liquid diet on the last day before the procedure.

What to do if you don't have a laxative prescription

If you don't have a laxative prescription for your endoscopy, you should contact your healthcare provider. They will be able to advise you on the best course of action and may provide you with a prescription if necessary. It is important to follow their instructions carefully to ensure the success of your endoscopy procedure.

• Contact your healthcare provider: Get in touch with the clinic or hospital where you are scheduled for your endoscopy. Ask to speak to a nurse or doctor who can advise you on the next steps. They may provide you with instructions on how to obtain a laxative prescription or recommend an alternative preparation method.
• Discuss your options: Depending on the type of endoscopy and your medical history, your healthcare provider may suggest different options. Be sure to disclose any relevant medical information, such as digestive issues or allergies, to help them determine the best approach.
• Obtain a prescription: If your healthcare provider determines that you need a prescription laxative, they can send it electronically to your pharmacy. Contact your pharmacy to confirm receipt of the prescription and request that it be filled. If there are any issues, don't hesitate to reach out to your gastroenterology doctor's office for assistance.
• Follow instructions carefully: Once you have obtained the prescribed laxative, carefully follow the instructions provided by your healthcare provider. This typically involves taking the laxative a certain number of hours before your procedure. It is important to adhere to the schedule to ensure that your bowels are properly cleansed for the endoscopy.
• Prepare for side effects: Taking a laxative can cause side effects such as nausea and stomach discomfort. Stay hydrated by drinking clear liquids, and follow any additional instructions provided by your healthcare provider to mitigate these side effects.
• Seek assistance if needed: If you experience any severe side effects or if your bowels are not cleansed properly after taking the laxative, contact your gastroenterology doctor as soon as possible. They can advise you on the necessary steps to ensure a successful endoscopy procedure.

Remember, it is important to consult with your healthcare provider if you have any concerns or questions about your endoscopy preparation, including the use of laxatives. They are there to ensure your procedure is safe and effective.

What to do if you don't think your laxative will work

If you are preparing for a colonoscopy or upper endoscopy, it is important to follow the instructions in your bowel preparation packet. This includes taking any laxatives as directed. If you don't think your laxative will work, here are some things you can do:

• Contact your gastroenterology doctor at least two weeks before your procedure to discuss alternative options and a diet plan. They may recommend a different type of laxative or a higher dose.
• Make sure you are taking the laxative correctly. Follow the schedule and instructions provided in your bowel preparation packet.
• Try to make lifestyle changes such as eating high-fiber foods, taking probiotics, drinking more fluids, and exercising. These changes can help improve digestion and may enhance the effects of the laxative.
• If you are experiencing side effects such as severe diarrhoea or constipation from the laxative, contact your healthcare provider. They can advise you on how to manage these side effects and determine if a different laxative is needed.
• Be patient and give the laxative time to work. It may take a few days for a gentle laxative to provide relief.
• If you are concerned about the safety or effectiveness of the laxative, consult your doctor or healthcare provider. They can assess your individual situation and provide guidance.

Remember, it is important to have a clean bowel before your procedure to ensure the success of the colonoscopy or endoscopy. Do not hesitate to reach out to your healthcare team if you have any doubts or concerns about the laxative or your bowel preparation.

What to do if you're still going to the toilet before your endoscopy

It is important to follow the instructions provided by your healthcare provider when preparing for an endoscopy or colonoscopy. This typically involves cleansing your bowels using a laxative formula, which can be prescribed or purchased over the counter.

If you are still going to the toilet before your endoscopy, it is important to continue following the instructions provided by your healthcare provider. Here are some things to keep in mind:

• Timing: Follow the schedule in your bowel preparation packet carefully. This includes the timing of when to take your laxative and when to expect bowel movements. It is important to finish the laxative as instructed, typically 4 hours before your scheduled arrival time.
• Diet: Continue to follow the recommended diet, which is typically a clear liquid diet on the day before the procedure. Avoid solid foods, milk, and milk products. Choose clear liquids such as apple juice, Sprite, ginger ale, tea, coffee (without milk), broth, Jell-O, and clear soup.
• Hydration: Drink plenty of clear liquids to stay hydrated. This includes water, broth, and electrolyte-containing sports drinks.
• Medications: Take your regular medications as instructed, unless advised otherwise by your healthcare provider. However, stop taking any medicines that thin your blood 3-5 days before the procedure, unless your provider advises otherwise. This includes aspirin, Plavix, Mobic, and Coumadin, among others.
• Transportation: Arrange for a friend or family member to provide transportation to and from the procedure, as you will be sedated and unable to drive.
• Contact: If you have any concerns or questions, don't hesitate to contact your healthcare provider or the endoscopy unit for guidance.

Remember, it is important to follow the specific instructions provided by your healthcare provider, as they may vary depending on your individual needs and the type of procedure you are undergoing.
