Dr Haydar Bolat
UK-registered GP and Clinical Director at MHW. Provides diabetes and pre-diabetes screening, interprets HbA1c and related results, and agrees prevention or management plans with patients.
View profileType 2 diabetes and pre-diabetes often develop quietly, with no obvious symptoms for years. A simple blood test (HbA1c) plus a risk review can tell you where you stand — and pre-diabetes, caught early, can often be reversed. We offer doctor-led screening with your results clearly explained and a practical plan.
Educational information — not a substitute for clinical assessment
This page explains diabetes screening in general terms. A diagnosis depends on blood results interpreted alongside your symptoms and risk factors. Screening tells you your current status; it is not a substitute for ongoing care if you are diagnosed.
Diabetes means blood glucose (sugar) is too high. In type 2 diabetes — the most common form — this develops gradually as the body becomes less responsive to insulin. Pre-diabetes is a warning stage where glucose is higher than normal but not yet in the diabetes range. It is important because it can often be reversed with the right changes, lowering your future risk.
Early type 2 diabetes frequently has no symptoms, which is why screening matters. When symptoms do appear, they can include:
Finding raised glucose before it becomes diabetes is genuinely valuable — with diet, activity and weight changes, many people bring their levels back to normal and avoid progressing.
The main screening test is HbA1c, a blood test that reflects your average blood glucose over the past 2–3 months. It does not need fasting. Depending on your situation we may also check a fasting glucose, and review related factors such as cholesterol, blood pressure, weight and kidney function for a fuller picture of your metabolic health.
We explain your HbA1c in plain terms — normal, pre-diabetes range, or diabetes range — alongside your other results and risk factors. A single result sometimes needs confirming with a repeat. We then agree what happens next, whether that is reassurance and rescreening, a prevention plan, or starting management if diabetes is confirmed.
Book if you have risk factors, symptoms, or simply want to know your status. Seek urgent help for very high thirst with drowsiness, vomiting, abdominal pain or rapid breathing, which need immediate assessment.
The consultation and HbA1c test are priced on our Fees page, with options to add related blood tests.
Not for HbA1c — it can be done at any time. If we add a fasting glucose or cholesterol, we will tell you whether to fast beforehand.
Turnaround depends on the test, and we explain your results with a doctor rather than just sending a number. We will confirm timing at your appointment.
Often, yes. Many people return to normal glucose with changes to diet, activity and weight — which is exactly why early screening is worthwhile.
We explain it clearly and start a management plan, and can coordinate ongoing care. With your consent we can share information with your NHS GP.
It depends on your risk and previous results. If you are at higher risk or in the pre-diabetes range, we will suggest when to recheck.
