Prediabetes: What It Means and What to Do About It
Prediabetes is the stage where sugar sits above normal but below the diabetes threshold. It is the point at which lifestyle change does the most work.
Prediabetes is often waved away as "sugar is a bit high". It is a warning — and the good news is that this is the stage where you have the most options.
The ranges
| Test | Prediabetes range |
|---|---|
| Fasting sugar | 100 – 125 mg/dL |
| HbA1c | 5.7% – 6.4% |
| 2 hours post-meal | 140 – 199 mg/dL |
Laboratories differ slightly, so read the range on your own report.
Symptoms
Most people have none. Some notice darkened skin at the neck or underarms. Prediabetes is almost always found by testing rather than felt.
What to do
- 30 minutes of activity on most days — brisk walking counts
- If weight is high, even a modest reduction shows up
- Stop sugary drinks — the single fastest-acting change
- Protein and fibre at every meal
- Get enough sleep
- Retest at the interval your doctor sets
How long does it take?
There is no fixed period. Some people see reports improve within months, others take longer, and in some it progresses. That is exactly why retesting matters — reading the number rather than guessing.
Is medication needed?
Lifestyle is usually tried first. In some situations doctors do start medication — it depends on your age, weight, other conditions and the report.
Frequently asked questions
Does prediabetes always become diabetes?+
Not necessarily. Many people improve with lifestyle change. Some progress, which is why regular testing matters.
Do I have to cut out sweets completely?+
Not completely. Cutting sugary drinks and daily sweets does most of the work.
When should I retest?+
Your doctor decides, typically in 6 to 12 months — sooner if your risk is higher.
Can thin people have prediabetes?+
Yes. It occurs at normal weight in India, so do not let weight alone decide whether you test.
