Adequate bowel preparation is a critical component of ensuring a successful colonoscopy, as it provides the clearest view of the colon and rectum, allowing the physician to detect potential abnormalities such as polyps, tumours, or inflammation. To achieve the best possible outcomes, it is essential to follow the prescribed preparation guidelines precisely.

Below is a comprehensive guide to ensure effective bowel preparation.

Adhere to Your Physician’s Instructions

Your gastroenterologist will provide personalised instructions for bowel preparation based on the type of solution prescribed. It is paramount to follow these directions carefully, as the effectiveness of the procedure largely depends on the thoroughness of bowel cleansing.

Dietary Adjustments Prior to the Procedure

: You may be instructed to reduce fibre intake to avoid residual material in the colon. High-fibre foods, such as whole grains, nuts, seeds, fruits, and vegetables, should be limited during this period.

Water, clear broths, and clear fruit juices (e.g., apple or white grape juice)

Plain gelatin (without artificial colours)

Avoid solid foods, dairy, alcohol, and beverages with pulp or artificial colouring, particularly red or purple, as they can interfere with the procedure.

Laxative Preparation: Key to Colon Cleansing

Your gastroenterologist will typically prescribe a bowel prep solution, designed to induce frequent bowel movements and thoroughly clear the colon. Important tips include:

: You will likely be asked to take the solution in two phases—half the dose the evening before your colonoscopy and the remaining portion several hours before the procedure. Ensure you follow the timing precisely to maximize effectiveness.

: In addition to the bowel prep solution, drinking ample 

 is essential. This helps prevent dehydration and ensures the solution works effectively. Continue to hydrate well throughout the preparation phase.

As the laxative solution begins to work, you will experience frequent and urgent bowel movements. It is crucial to stay near a bathroom during this phase, as the colon empties rapidly. Have items such as wet wipes and soothing ointments on hand to minimise discomfort.

Adequate hydration is essential during bowel prep, as the process can lead to fluid loss. Aim to drink plenty of 

, but avoid drinks with dyes or pulp. Staying well-hydrated will help alleviate potential side effects like dizziness or fatigue and support the effectiveness of the laxatives.

Discuss any regular medications with your gastroenterologist. Certain medications, such as those for diabetes, hypertension, or heart disease, may need to be adjusted before the procedure. Some medications may need to be temporarily suspended, particularly those that affect blood clotting or gastrointestinal motility. Always consult your healthcare provider regarding the timing of your medications during the prep period.

 and any liquids that are not part of the clear liquid diet.

, as it can lead to dehydration and interact with your medications.

Refrain from drinking beverages with artificial colours (e.g., red, purple, or blue) as these can mimic blood during the colonoscopy, potentially complicating interpretation of the results.

While bowel preparation is generally well-tolerated, some individuals may experience nausea, bloating, or mild abdominal cramping. These symptoms are typically temporary but can be distressing. If you have trouble tolerating the solution, or experience excessive discomfort, contact your gastroenterologist for guidance.

 prior to your procedure. This means no food or drinks (except for clear liquids) should be consumed within this period. This ensures that your stomach is empty, reducing the risk of aspiration during sedation and making the procedure safer and more effective.

After the colonoscopy, you will be monitored as the effects of sedation wear off. Due to the sedative medications used, you will not be able to drive or operate machinery, so it is important to arrange for transportation home. You may feel slightly bloated or experience mild cramping after the procedure, but these symptoms usually resolve within a few hours.

Proper bowel preparation is essential for a high-quality colonoscopy. By following your doctor’s instructions for diet, medication, and the bowel prep solution, you will help ensure that the procedure is as effective as possible. The clearer your colon is, the more likely it is that any potential issues—such as colorectal cancer, polyps, or inflammatory conditions—will be detected early, improving outcomes and enabling timely intervention.

If you have any questions or concerns about the bowel preparation process, please reach out to your gastroenterologist.

Maintaining optimal gut health is crucial for overall well-being, as the digestive system plays a vital role in nutrient absorption, immune function, and even mental health. In this blog post, we will explore what gut health is, why it matters, and practical tips to promote a healthy digestive system.

Gut health refers to the balance and function of the gastrointestinal (GI) tract, which includes the stomach, small intestine, and large intestine (colon). A healthy gut is characterised by a diverse community of beneficial bacteria (microbiota), effective digestion and absorption of nutrients, a robust immune system, and minimal inflammation or gastrointestinal symptoms.

Nutrient Absorption: Proper digestion allows the body to absorb essential nutrients from food efficiently.

Immune System Support: The gut microbiota plays a crucial role in immune function, helping to protect against infections and regulate inflammation.

Mental Health: Emerging research suggests a link between gut health and mental well-being, influencing mood and cognitive function.

Overall Well-Being: A healthy gut can reduce the risk of digestive disorders such as irritable bowel syndrome (IBS).

Eat a Balanced Diet: Include a variety of fibre-rich foods (fruits, vegetables, whole grains), probiotics and prebiotics (garlic, onions, bananas) to support a diverse microbiota.

Stay Hydrated: Drinking plenty of water helps maintain digestive health and prevents constipation.

Manage Stress: Chronic stress can impact gut health. Practise relaxation techniques such as deep breathing, meditation, or yoga.

Exercise Regularly: Physical activity supports healthy digestion and helps maintain a balanced microbiome.

Limit Unhealthy Habits: Reduce intake of processed foods, sugary snacks, and excessive alcohol, which can disrupt gut bacteria balance.

Get Enough Sleep: Aim for 7-8 hours of quality sleep each night to support overall health, including digestive function.

Avoid Smoking: Smoking can harm the digestive system

If you experience persistent digestive symptoms such as abdominal pain, bloating, diarrhoea, or constipation, it's essential to consult with a gastroenterologist. They can evaluate your symptoms, perform diagnostic tests if needed, and recommend appropriate treatment to address any underlying gastrointestinal issues.

Prioritising gut health through healthy lifestyle choices can have profound benefits for your overall well-being. By nourishing your gut with a balanced diet, managing stress, and adopting healthy habits, you can support a healthy digestive system and enjoy a better quality of life.

Recent update to bowel cancer screening age

As of July 1, 2024, the National Bowel Cancer Screening Program lowered the eligibility age for free, at-home faecal occult blood testing (FOBT) from 50 to 45 years.

As part of the National Bowel Cancer Screening Program, eligible patients receive a free at-home FOBT.

A positive FOBT result indicates the presence of hidden blood in the stool, which can be a sign of various gastrointestinal conditions. It's important to note that whilst FOBT is a useful screening tool, it does not directly detect colorectal cancer but suggests the need for further investigation.

Potential Causes of Positive FOBT Results:

 A positive FOBT can be indicative of colorectal cancer, though not all positive results are due to cancer.

 Benign growths and precancerous growths can bleed leading to positive FOBT results.

 Conditions like diverticulosis can cause bleeding in the colon, resulting in a positive test.

 Swollen blood vessels in the rectum or anus can bleed, leading to positive results.

 Conditions like ulcerative colitis or Crohn's disease can cause intestinal bleeding.

 Abnormal blood vessels in the colon can lead to bleeding detected by FOBT.

If a FOBT result is positive, a colonoscopy is typically recommended to identify the source of bleeding. This procedure helps in diagnosing the underlying cause of the bleeding, facilitating early intervention, and improving patient outcomes.

Recent updates to colorectal cancer screening guidelines in Australia have introduced significant changes to the recommended starting age for FOBT. As of July 1, 2024, the National Bowel Cancer Screening Program lowered the eligibility age for free, at-home FOBT from 50 to 45 years. This means that individuals aged 45 to 74 are now encouraged to participate in biennial (every two years) screening

 The recommended age to begin FOBT screening is now 45 years for individuals at average risk of bowel cancer

 Eligible individuals should complete the free, at-home FOBT every two years.

 Those aged 50 to 74 will continue to receive test kits by mail. Individuals aged 45 to 49 can request their first kit online or by calling the National Cancer Screening Register

These changes aim to enhance early detection of bowel cancer, improving treatment outcomes. It's important to note that individuals with a family history of bowel cancer or other risk factors may need to start screening earlier or undergo more frequent testing. Consulting with a healthcare provider can help determine the most appropriate screening schedule based on personal risk factors.
