Before your procedure
Every endoscopy begins with a consultation so the right test is chosen for your symptoms. You will receive written preparation instructions and have the chance to discuss sedation and any concerns before the day.
On the day at The Oaks
Procedures take place in the endoscopy unit at The Oaks Hospital, Mile End Road, Colchester. You will be looked after by an experienced nursing team, and findings are explained to you before you go home.
Afterwards and follow-up
A written report is issued for you and your GP. If biopsies were taken, results are typically available within a few weeks and reviewed at a follow-up appointment with a clear plan for treatment or surveillance.
Endoscopy FAQs
What types of endoscopy are available in Colchester?+
Dr Karunakaran performs gastroscopy (OGD), colonoscopy, therapeutic endoscopy, ERCP and endoscopic ultrasound (EUS). Diagnostic procedures are carried out at The Oaks Hospital in Colchester; advanced procedures are arranged at an appropriate specialist unit.
How quickly can I have an endoscopy privately?+
Private endoscopy in Colchester is typically available within days rather than weeks, and can often be arranged shortly after your initial consultation.
Is endoscopy safe?+
Diagnostic endoscopy is a very safe, routine procedure. Serious complications such as bleeding or perforation are rare, and the specific risks for your procedure are explained during consent before you go ahead.
Can I eat and drink before an endoscopy?+
No. Gastroscopy requires an empty stomach — usually no food for six hours and no clear fluids for two hours. Colonoscopy requires bowel preparation the day before along with dietary restrictions. Written instructions are supplied when you book.
Will the same consultant do my procedure?+
Yes. Dr Karunakaran personally performs the endoscopy for the patients he assesses, so the consultant who takes your history is the one who examines you and follows up your results.
Do I need a GP referral?+
Self-pay patients can usually self-refer. Most private medical insurers require a GP referral letter before they will authorise an endoscopy.
