Overview
A colonoscopy examines the lining of the large bowel using a thin, flexible camera, commonly used to investigate bowel habit changes, bleeding or abdominal pain, and to screen for bowel cancer. Mr Alan Woodward performs colonoscopy for both diagnostic and screening purposes across South Wales and Bristol, drawing on decades of colorectal experience to identify and manage findings appropriately.
How it’s performed
A colonoscopy involves passing a flexible colonoscope through the rectum to examine the full length of the large bowel, with the option to take biopsies or remove polyps during the same procedure.
- Bowel preparation instructions provided in advance
- Sedation or gas and air offered for comfort
- Careful examination, with biopsies or polyp removal if needed
- A same-day discussion of findings, with written follow-up
Recovery & Aftercare
Most patients go home the same day once sedation has worn off enough for safe discharge, with any mild bloating settling quickly. Sedated patients should avoid driving or important decisions for the rest of the day. Results and any biopsy findings are usually discussed straight away or at a prompt follow-up.
Is Colonoscopy Right for Me?
The best way to find out is a consultation. Mr Woodward will review your symptoms and history, explain what to expect and recommend the right next step.
Frequently Asked Questions
What is a colonoscopy used for?
A colonoscopy examines the lining of the large bowel to investigate symptoms such as bleeding or changed bowel habit, and to screen for polyps or early bowel cancer. It allows biopsies to be taken and polyps removed during the same procedure where needed.
Is a colonoscopy painful?
Most patients experience mild discomfort rather than pain, particularly with sedation or gas and air available throughout. Some bloating or cramping can occur afterwards but typically resolves within a few hours.
How long does a colonoscopy take?
The procedure itself usually takes between 20 and 45 minutes, though patients should allow additional time for preparation, sedation and recovery on the day. Mr Woodward’s team will confirm expected timings when booking.
Do I need to prepare for a colonoscopy?
Yes, bowel preparation is required beforehand to clear the colon so it can be examined thoroughly. Clear written instructions, including dietary changes and preparation medicine, are provided ahead of the appointment.
How often should I have a colonoscopy?
This depends entirely on individual risk factors, family history and previous findings, so there is no single answer that applies to everyone. Mr Woodward will advise on appropriate timing for future colonoscopies based on personal circumstances.
Can polyps be removed during a colonoscopy?
Yes, small polyps can typically be removed during the same colonoscopy procedure and sent for analysis. This is one of the key benefits of colonoscopy in preventing bowel cancer before it develops.
