Prediabetes: Can You Reverse It?

Q: What HbA1c level is prediabetes?

An HbA1c of 5.7 to 6.4% is the commonly used range for prediabetes. Below 5.7% is considered normal, and 6.5% or above is in the diabetes range. It is interpreted together with fasting and post-meal sugar.

Q: How long does it take to reverse prediabetes?

There is no fixed timeline; it depends on the starting point and how consistently changes are made. Many people see improvement over a few months of sustained changes, confirmed by repeat testing.

Prediabetes means your blood sugar is higher than normal but not yet in the diabetes range — and in many people it can be brought back to normal with the right changes, before it becomes diabetes. Dr. Manuj Sondhi, MRCP (UK), a Consultant Physician & Diabetologist at Nirvana Clinic, Greater Noida, helps people with prediabetes or "borderline sugar" act early.

The Basics

What Counts as Prediabetes

Prediabetes is a stage where blood sugar is raised but has not reached the level used to diagnose diabetes. It is a warning sign — and also an opportunity, because this is the stage where progression can most often be slowed or reversed. The values below are the commonly used reference ranges (your doctor interprets them alongside your overall picture):

Test	Normal	Prediabetes	Diabetes
HbA1c	Below 5.7%	5.7–6.4%	6.5% or above
Fasting glucose	Below 100 mg/dL	100–125 mg/dL	126 mg/dL or above
2-hour post-meal	Below 140 mg/dL	140–199 mg/dL	200 mg/dL or above

The Good News

Can Prediabetes Be Reversed?

Often, yes. Unlike established diabetes, prediabetes frequently returns to normal blood sugar when the underlying drivers — weight, diet pattern and physical activity — are addressed early. In the landmark Diabetes Prevention Program (DPP) study, structured lifestyle change reduced the risk of progressing from prediabetes to type 2 diabetes by around 58% over about three years — more than medication did in the same trial.

That doesn't mean it happens automatically or for everyone. Results vary from person to person, and the earlier and more consistently the changes are made, the better the chance of returning to normal and staying there.

Why acting now matters

Left unaddressed, a meaningful proportion of people with prediabetes go on to develop type 2 diabetes over the following years. Catching it at the prediabetes stage gives the best window to avoid that.

Common Questions

Prediabetes — FAQs

What HbA1c level is prediabetes?

An HbA1c of 5.7–6.4% is the commonly used range for prediabetes. Below 5.7% is considered normal, and 6.5% or above is in the diabetes range. Your doctor interprets this together with your fasting and post-meal sugar.

Can prediabetes go back to normal?

In many people, yes. Prediabetes often returns to normal blood sugar with earlier weight, diet and activity changes — which is why it's worth acting at this stage rather than waiting. Outcomes vary between individuals.

How long does it take to reverse prediabetes?

There is no fixed timeline — it depends on the starting point and how consistently changes are made. Many people see improvement in their numbers over a few months of sustained changes, confirmed by repeat testing.

Do I need medication for prediabetes?

For most people the first approach is lifestyle change. Medication is considered only in selected situations based on clinical guidelines and an individual discussion with your doctor — it is not automatic.
