Colonoscopy

A colonoscopy is recommended for investigating specific digestive symptoms and diagnosing colon diseases. Common symptoms that warrant a colonoscopy include:

• Persistent changes in bowel habits, such as diarrhoea or constipation.
• Blood or mucus in stool.
• Unexplained weight loss.
• Abdominal pain, bloating, or discomfort.
• Iron deficiency anaemia.

Colonoscopy is also a crucial tool for colon cancer colonoscopy screening and prevention. It reduces the risk of colon cancer by detecting and removing precancerous polyps before they become malignant. Individuals aged 45 and above, or those with a family history of colon cancer, should prioritise regular colonoscopies.

Colonoscopy is the gold standard for colon cancer screening. It allows early detection of precancerous polyps and early-stage cancers, significantly reducing the risk of developing advanced colon cancer.

Screening is generally recommended for adults aged 45 and above, or earlier for those with a family history of colon cancer or certain genetic conditions. Both men and women benefit from regular screening, as early detection improves treatment outcomes and survival rates.

During a screening colonoscopy, the gastroenterologist can identify and remove polyps immediately, preventing them from developing into cancer. Colonoscopy screening is typically performed every 10 years for average-risk individuals, but your specialist may recommend a shorter interval depending on personal risk factors or previous findings.

To ensure a successful colonoscopy, patients must follow specific preparation guidelines:

• Fasting: Avoid food for at least 6 hours before the procedure. Clear fluids can be consumed up to 2 hours prior.
• Bowel Preparation: Take prescribed medications to clear the bowels, following the instructions carefully.
• Medication Adjustments: Most medications can be continued, but diabetic drugs should be omitted during fasting. Blood thinners may need to be paused, as advised by your colonoscopy doctor.
• Post-Procedure Care: Avoid driving, working, or making major decisions after the procedure due to the effects of sedation. Arrange for someone to take you home.

Before the procedure, a nurse will conduct preliminary checks and insert an intravenous line for sedation.

During the colonoscopy, you will lie on your left side, and sedation will be administered to ensure comfort. Once you are asleep, the procedure begins. You will not feel or remember anything during the process.

After the procedure, you will be looked after in a recovery area or room, where medical staff will monitor you until the effects of the anaesthesia have worn off. Nurses will provide light refreshments and ensure you are ready for discharge. It is advisable to arrange for a family member to receive discharge instructions and accompany you home. You should avoid driving, working, or engaging in significant activities until the following day. Mild abdominal discomfort or bloating is normal after a colonoscopy and typically resolves within 24 hours.

Your colonoscopy doctor will schedule a follow-up appointment to review the procedure, discuss the findings, including any biopsy results, and outline an appropriate management plan moving forward.
