What is a diagnostic colonoscopy?
A diagnostic colonoscopy is a procedure to examine the lining of the large bowel using a thin, flexible camera. It is the most accurate investigation available for evaluating symptoms such as rectal bleeding, a change in bowel habit, abdominal pain, and unexplained anaemia.
Mr Daulatzai is an accredited endoscopist and performs colonoscopies in a comfortable, private setting. The procedure is carried out under sedation, ensuring you are relaxed and comfortable throughout. Results and next steps are discussed with you on the same day.
When a diagnostic colonoscopy is recommended
Diagnostic colonoscopy is the most accurate investigation for evaluating the lining of the large bowel. It is recommended for persistent rectal bleeding, a sustained change in bowel habit, unexplained abdominal pain, iron-deficiency anaemia, positive faecal immunochemical test (FIT), or to investigate abnormalities seen on imaging.

Preparation and what to expect
Thorough bowel preparation is essential for a high-quality examination. You will receive clear instructions on dietary modification and laxatives before your appointment. Good preparation improves detection of polyps and small lesions and reduces the need for repeat examinations.
On the day, nursing staff guide you through admission and consent. I review your medical history, explain the procedure again, and answer questions before sedation and examination begin. Suspicious areas can be biopsied during the procedure for laboratory analysis.
You must arrange for a responsible adult to escort you home after sedation and avoid driving, signing legal documents, or operating machinery for 24 hours.
After your colonoscopy
You receive a summary of findings and preliminary advice before discharge. If biopsies are taken, results are reviewed when available and follow-up arranged if further treatment or surveillance is needed.
Serious complications are uncommon but include bleeding or perforation; I discuss these risks before the procedure. Most patients feel back to normal within 24 hours aside from mild bloating or wind.
Your consultation
If you have symptoms requiring bowel investigation, specialist assessment ensures the right test at the right time. Appointments are available through NHS referral and private practice across London and Hertfordshire.

Frequently asked questions
How do I prepare for a colonoscopy?
You will receive detailed written instructions prior to your procedure. In general, you will be asked to follow a low-residue diet for one to two days beforehand and to take a bowel preparation solution to clear the bowel. You will need to arrange for someone to drive you home following the procedure if sedation is used. Full pre-procedure instructions will be provided by the clinical team.
What happens at my first consultation?
Your first appointment will typically last 30 to 45 minutes. Mr Daulatzai will take a full history, review any relevant investigations, and examine you where appropriate. He will explain your diagnosis and all available treatment options clearly, and involve you fully in any decisions about your care. There is no obligation to proceed with any treatment at the initial consultation.
How quickly can I be seen?
Private patients can typically be seen within one week. Please contact the secretary directly to check current availability.
