What Prediabetes Really Means
Prediabetes is a stage where your blood sugar is higher than normal, but not yet high enough to be called type 2 diabetes. Many patients in Hyderabad first hear the words "borderline sugar" during a routine health check or an insurance screening, and understandably feel confused — is it diabetes or not?
Think of prediabetes as a yellow traffic light. You have not crossed into diabetes yet, but your body is already struggling to keep blood sugar in the safe zone. The good news is that this is one of the few health conditions where timely action can genuinely turn things around. It is a window of opportunity, not a sentence.
Behind the scenes, the usual culprit is insulin resistance — a state where your body still makes insulin (the hormone that moves sugar from the blood into your cells for energy), but the cells stop responding to it properly. Sugar then builds up in the blood instead of being used.
How Prediabetes Is Diagnosed
Prediabetes is diagnosed with simple blood tests — the same ones used for diabetes, just read at slightly lower cut-offs. You do not need any special or expensive investigation to find out.
- Fasting blood sugar: 100 to 125 mg/dL (normal is below 100; diabetes is 126 or above).
- HbA1c: 5.7% to 6.4% (this reflects your average sugar over the past 2 to 3 months; below 5.7% is normal).
- Oral glucose tolerance test (2-hour value): 140 to 199 mg/dL after a measured sugar drink.
Why South Asians Are at Higher Risk
People of Indian origin tend to develop insulin resistance at lower body weights and younger ages than many other populations. This is sometimes described as the "thin outside, fat inside" pattern — you may look slim but carry more fat around the abdomen and internal organs, which quietly drives blood sugar problems.
In Hyderabad specifically, a few everyday factors add up: diets rich in white rice, refined flour (maida), sweets and fried snacks; long hours of sitting at desks and in traffic; high stress; and a strong family history of diabetes in many households. If a parent or sibling has type 2 diabetes, your own risk is meaningfully higher.
- Being overweight, especially a large waistline (over 90 cm for men, over 80 cm for women).
- A family history of type 2 diabetes.
- Age above 35 to 40, though prediabetes is increasingly seen in younger people too.
- Women who had diabetes during pregnancy (gestational diabetes) or who have PCOS.
- High blood pressure, or abnormal cholesterol and triglycerides.
The Quiet Symptoms — and Why Screening Matters
Prediabetes usually causes no symptoms at all. That is exactly why it is so easily missed. Some people do notice subtle changes, such as feeling more tired than usual, increased thirst, or a darkening of the skin in the neck and armpit folds (a sign called acanthosis nigricans that often points to insulin resistance).
Because it stays silent, the only reliable way to catch prediabetes is to test for it. If you have any of the risk factors above, a yearly fasting sugar and HbA1c is a small, worthwhile investment. Catching it early is far easier than managing full diabetes and its complications later on.
The Numbers That Should Reassure You
Large studies, including landmark research done here in India, have shown that structured lifestyle changes can cut the risk of prediabetes progressing to type 2 diabetes by roughly half. In other words, what you do over the next year or two truly matters.
Even modest changes count. Losing just 5 to 7 percent of your body weight — for someone weighing 80 kg, that is about 4 to 6 kg — combined with regular activity, can shift your sugar back toward the normal range. You do not need a dramatic transformation; you need consistent, realistic steps you can sustain over time.
Practical Steps to Reverse Prediabetes
The plan for prediabetes is refreshingly straightforward. It centres on four things — food, movement, sleep and stress — with no complicated regimen required.
- Rebalance your plate: fill half with vegetables and salad, a quarter with protein (dal, eggs, paneer, fish, chicken, sprouts), and only a quarter with carbohydrates. Prefer whole grains like millets (jowar, bajra, ragi) and brown rice over polished white rice and maida.
- Cut back on sugary tea, soft drinks, packaged juices, bakery items and fried snacks — the everyday extras that quietly push sugar up.
- Move most days: aim for about 150 minutes of brisk walking or activity a week, spread across the days. A 30-minute walk after dinner is especially helpful for blood sugar.
- Add some strength work twice a week — bodyweight exercises or light weights build muscle, and muscle uses up glucose.
- Protect your sleep and manage stress, as poor sleep and constant tension both worsen insulin resistance.
- Do not smoke, and keep alcohol to a minimum.
When to See a Doctor, and What to Expect
If a report shows a fasting sugar of 100 to 125 mg/dL or an HbA1c between 5.7 and 6.4 percent, treat it as a prompt to consult a physician rather than a reason to panic. A proper evaluation looks at the full picture — your weight, blood pressure, cholesterol, family history and lifestyle — and builds a plan around your actual routine, including your food habits and work schedule here in Hyderabad.
For most people, lifestyle change is the first and main treatment. In selected cases — for example, younger patients at very high risk, or those who do not respond to lifestyle measures alone — a doctor may consider adding medication. That decision, and any prescription, should always be made and monitored by your treating physician. Please do not start or stop any medicine on your own.
