A colonoscopy is a diagnostic procedure to check inside your bowel to find out the cause of your bowel symptoms. The procedure uses a narrow, flexible, telescopic camera called a colonoscope to look inside your large bowel, also known as the large intestine or colon. The large bowel is the last part of your digestive tract, absorbing water from the remaining indigestible food and moving the waste from the body.
When is a colonoscopy advised?
A colonoscopy is often advised when you are experiencing the following bowel symptoms:
- bleeding from your bottom or blood in your poo
- persistent diarrhoea or constipation
- a change in your bowel habits
- abdominal pain
- weight loss for no known reason
- a raised temperature, feeling generally unwell, feeling or being sick, and extreme fatigue, in combination with any of the above
A colonoscopy can be used to look for bowel conditions like:
- Crohn’s disease
- Diverticular disease or diverticulitis
- Ulcerative colitis
- Colorectal cancer
- Internal haemorrhoids
Most of the time it will not find anything to worry about. But sometimes it might find something that needs a closer look or further testing.
What to expect
You may be asked to modify your diet to very plain food in the days leading up to having the procedure. Your bowel will need to be completely empty for the procedure so you will be given a strong laxative to take the day before. The laxative can make you open your bowels very quickly and you may feel some discomfort or bloating in your tummy so it’s best to be at home and able to relax.
The procedure will take 30 to 45 minutes. You may be offered sedation to help you relax. The colonoscope, a thin, flexible tube, will be inserted into your colon. Air will be pumped in to your rectum to open up your bowels so the tube can go through all of your large bowel. You may feel little discomfort and maybe some bloating or cramping, but you will not feel pain.
Any polyps (growths) will be removed during the procedure but you will not be able to feel this. A sample may be taken of any tissue removed so a biopsy can be performed. It’s not uncommon to have polyps in your bowels, and most of the time they’re harmless. However, they can sometimes become cancer so they need to be checked.
After the procedure
Following the procedure you will feel bloating but this will pass within a few hours. Patients can usually go home after 2 hours. You may have some bleeding but this is normal. You should be able to return to work the next day unless otherwise advised.
