Dr Thines Karunakaran
Consultant Gastroenterologist
Reasons for a colonoscopy
A colonoscopy examines the whole large bowel with a thin flexible camera, and allows polyps to be removed and biopsies taken at the same time. It is commonly recommended for:
- Rectal bleeding or blood in the stool
- A persistent change in bowel habit
- Unexplained abdominal pain or bloating
- Iron deficiency anaemia
- Unexplained weight loss
- Suspected or known inflammatory bowel disease
- Bowel cancer screening or a family history of bowel cancer
- Surveillance after previous polyps
What happens on the day
You will be admitted, checked by the nursing team and see Dr Karunakaran to go through consent and sedation options. The examination itself takes 20–40 minutes, after which you rest in recovery and are given your findings before going home.
Polyp removal and biopsies
Polyps found during the examination can usually be removed there and then, which reduces future bowel cancer risk. Small tissue samples may also be taken and sent to the laboratory for analysis.
Insured and self-pay
Recognised by all major insurers including Bupa (Fee Assured), AXA Health, Aviva, Vitality, WPA, Healix and Allianz. Self-pay packages are available and quoted in advance.
Colonoscopy FAQs
How much does a private colonoscopy cost in Colchester?+
Self-pay packages at The Oaks Hospital usually cover the procedure, sedation, nursing care and any biopsies taken, and are quoted before you book. If you are insured with Bupa, AXA, Aviva, Vitality, WPA, Healix or Allianz, the cost is normally covered once your insurer has authorised the test.
How do I prepare for a colonoscopy?+
You will be given a bowel preparation drink to take the day before, along with written instructions on diet and which medicines to pause. A clear bowel is essential for an accurate examination, so following the instructions closely matters more than anything else you do on the day.
Is a colonoscopy painful?+
Most patients describe cramping or pressure rather than pain. Sedation and pain relief are routinely offered, and Entonox (gas and air) is also available. Dr Karunakaran will discuss the options with you before the procedure.
How long does a colonoscopy take?+
The examination usually takes 20–40 minutes, with additional time for preparation and recovery. Allow around half a day at the hospital in total, and arrange for someone to take you home if you choose sedation.
When will I get my colonoscopy results?+
Dr Karunakaran explains what was seen on the day, immediately after your procedure. If biopsies or polyps were taken, laboratory results usually take a few weeks and are discussed at your follow-up appointment.
Do I need a referral for a private colonoscopy?+
Self-pay patients can usually self-refer. Most insurers ask for a GP referral letter before authorising a colonoscopy, so it is worth checking with your insurer first.
