Prediabetes Explained: What Your Blood Sugar Results Mean
You go for a routine health checkup, collect your reports, and notice that your blood sugar is slightly above the normal range. You feel fine, so you wonder whether it really needs attention.
Then your doctor mentions “prediabetes.”
It is an unfamiliar word for many people, and it usually brings up two questions: Do I already have diabetes? Will I need medicines?
Prediabetes means your blood sugar is higher than normal, but below the range used to diagnose diabetes. It deserves attention, but developing type 2 diabetes is not inevitable. Changes to your daily habits, along with regular medical follow-up, can help reduce that risk.
What Happens in Prediabetes?
After you eat, your body breaks down carbohydrates into glucose, which enters your bloodstream. A hormone called insulin helps glucose move into your cells, where it is used for energy.
Sometimes, the cells stop responding to insulin as effectively as they should. Your body tries to compensate by producing more insulin. Over time, it may struggle to keep blood sugar within the normal range.
This reduced response to insulin is called insulin resistance, and it commonly plays a role in prediabetes.
Understanding Your Blood Sugar Report
Doctors use laboratory blood tests to check for prediabetes. The commonly used ranges below apply to people who are not pregnant.
| Test | Normal range | Prediabetes range | Diabetes range |
|---|---|---|---|
| HbA1c | Below 5.7% | 5.7%–6.4% | 6.5% or higher |
| Fasting plasma glucose | Below 100 mg/dL | 100–125 mg/dL | 126 mg/dL or higher |
| Two-hour oral glucose tolerance test | Below 140 mg/dL | 140–199 mg/dL | 200 mg/dL or higher |
The oral glucose tolerance test measures blood sugar two hours after a standard glucose drink. It is different from a routine blood sugar test taken after a meal. Pregnancy testing uses different criteria.
HbA1c reflects your average blood sugar over roughly the previous three months and does not usually require fasting. A fasting glucose test measures your level after at least eight hours without food.
For example, an HbA1c of 6.0% falls within the prediabetes range. Your doctor may recommend repeat testing to confirm the result. Conditions such as certain types of anaemia can affect HbA1c accuracy, so the number should be interpreted alongside your medical history.
Can You Have Prediabetes Without Symptoms?
Yes. Prediabetes often has no noticeable symptoms. Feeling well does not necessarily mean your blood sugar is normal.
Testing is particularly worth discussing if you have a parent or sibling with type 2 diabetes, carry excess weight, spend much of your day sitting, have PCOS, or have previously had diabetes during pregnancy. These factors can increase your risk.
What Can You Change in Your Daily Routine?
You do not have to change everything overnight. Start with habits you can realistically continue.
Look at the Whole Meal
Cutting down on sweets is useful, but meal portions and sugary drinks matter too.
If lunch is mostly rice with a little curry, try adjusting the balance: a smaller rice portion, more vegetables, and a protein source such as dal, eggs, fish or tofu. Choose water or unsweetened drinks more often, and make room for fibre-rich foods.
A healthy eating plan should fit your usual food preferences and nutritional needs. It should also be practical enough to follow beyond the first few weeks.
Make Movement Part of Your Week
Regular activity can help lower the risk of developing type 2 diabetes. A common goal is at least 150 minutes of moderate activity each week, such as brisk walking.
If you are currently inactive, begin with shorter walks and build up gradually. If you have a heart condition, significant joint pain or another health concern, discuss a suitable activity plan with your doctor.
Discuss a Suitable Weight Goal
For people who are overweight, losing around 5%–7% of their starting weight can help reduce diabetes risk. For someone weighing 80 kg, that is approximately 4–5.6 kg.
This is a gradual goal, not a reason to start a crash diet. Your doctor can help decide whether weight loss is appropriate for you.
Does Prediabetes Always Need Medicine?
Not everyone with prediabetes needs medication. Healthy eating, physical activity and weight management are central parts of care.
For some people at higher risk, a doctor may also consider metformin. The decision depends on your results, medical history and individual risk factors.
Frequently Asked Questions
Can blood sugar return to the normal range?
Yes, it can. However, improvement is not guaranteed, and continued healthy habits and follow-up remain important.
How often should I repeat my tests?
People with prediabetes are generally tested for diabetes at least once a year. Your doctor may recommend an earlier review depending on your results.
Do I have to stop eating rice completely?
Not necessarily. Portion size, the foods you eat alongside rice, and your overall eating pattern all matter. Ask your care team to help you plan meals around foods you normally eat.
