Prediabetes

Overview

Prediabetes means your blood sugar is above the normal range but not yet high enough to be called diabetes. It is a warning sign, not a disease sentence: with the right changes, many people bring their sugar back to normal and avoid developing diabetes altogether. The challenge is that prediabetes has no symptoms, so it is usually found only on a fasting sugar or HbA1c test — often during a routine check-up.

Think of prediabetes as the body asking for help before real damage begins. The pancreas is still producing insulin, but the cells are starting to resist it. At this stage the process is largely reversible, which is why identifying and acting on prediabetes is one of the most worthwhile things you can do for your long-term health.

What prediabetes means

Blood sugar normally stays within a narrow range. In prediabetes, fasting sugar sits between 100 and 125 mg/dL, or the HbA1c sits between 5.7% and 6.4%. These numbers are above normal but below the diabetes threshold. They tell us the body is already struggling to keep sugar in range — and without changes, many people with prediabetes develop type 2 diabetes within a few years.

Importantly, prediabetes is not a mild version of diabetes. It carries its own risks — including a higher chance of heart disease — and it is the single best window to act. Weight loss, regular activity and dietary changes at this stage are far more effective than waiting until diabetes is established.

Who should be checked

• Anyone with a family history of diabetes in a parent or sibling.
• People who are overweight, especially carrying weight around the waist.
• Women with a past history of diabetes in pregnancy (gestational diabetes) or a baby weighing over 4 kg.
• Adults with high blood pressure, cholesterol abnormalities or a known fatty liver.
• Anyone over 35 who has not had a sugar test in the last year.
• People with polycystic ovary syndrome (PCOS).

How prediabetes is diagnosed

Prediabetes is diagnosed purely from blood tests, since there are no symptoms to notice. Dr. Nayak uses the standard accepted criteria and, where a result is borderline, confirms it with a second test on a different day to avoid a false label.

• Fasting blood sugar (after at least 8 hours without food) — 100–125 mg/dL suggests prediabetes.
• HbA1c — the three-month average — 5.7% to 6.4% suggests prediabetes.
• A post-meal or glucose-drink test may be used when fasting results are borderline.

Reversing prediabetes

Prediabetes can often be returned to a normal range without medication. The most effective steps are also the most sustainable:

• Losing even 5–7% of body weight — for many people, that is just a few kilograms.
• Building regular activity into your day, such as a brisk walk after meals.
• Adjusting meal patterns to reduce sugar spikes — smaller, regular meals with more fibre and protein.
• Cutting back on sugary drinks, sweets and refined starches.
• Improving sleep and managing stress, both of which quietly raise sugar.

Medication is not usually needed at this stage, but in selected higher-risk people a short course of treatment may be discussed. The emphasis is firmly on lifestyle, with regular retesting to confirm the numbers are moving in the right direction.

How we help

Dr. Nayak interprets your reports accurately, identifies the reversible factors driving your sugar up, and gives you a practical, realistic plan — diet, activity and weight targets — to bring the numbers back to normal. Regular retesting keeps you on track and catches any drift early, so a borderline result never silently becomes diabetes. Consultations are available in-clinic in Bhubaneswar and over teleconsultation.
