Have you been told your blood sugar is "a little high" but not quite diabetes? That in-between stage has a name. It is called prediabetes, and it is far more common than most of us think. Millions of Indians are walking around with a pre diabetic condition without even knowing it.
The good news? This is one health warning you can actually do something about. Let me explain what prediabetes really means, the symptoms to watch for, and how you can turn things around.
What is Prediabetes and Why Should You Care?
Prediabetes is a stage where your blood sugar levels are higher than normal, but not high enough to be called type 2 diabetes. Think of it as a yellow signal at a traffic junction. You have not crossed into danger yet, but if you keep going at the same speed, diabetes is waiting on the other side.
Your body runs on glucose, a type of sugar that comes from the food you eat. A hormone called insulin helps move that sugar from your blood into your cells for energy. In prediabetes, your cells stop responding to insulin the way they should. Doctors call this insulin resistance. Sugar then starts building up in your blood.
Left alone, many people with a pre diabetic condition go on to develop full diabetes within a few years. But that is not a fixed destiny. Caught early, it can be slowed, and very often reversed.
How Common is Prediabetes in India?
More common than you would guess. The large ICMR-INDIAB study, published in The Lancet Diabetes and Endocrinology, estimated that around 136 million Indians are living with prediabetes, alongside 101 million with diabetes. That is a staggering number. And here is the worrying part, many of them have no idea, because the early signs of diabetes are so easy to miss.
What Are the Common Prediabetes Symptoms?
Here is the tricky bit. Prediabetes often has no clear symptoms at all. You can feel perfectly fine while your blood sugar quietly creeps up. That is exactly why it slips under the radar for so long.
Still, some people do notice subtle changes. You might feel more tired than usual, even after a good night's sleep. You may feel thirsty often, or find yourself heading to the loo more than before. Some notice blurred vision, slow-healing cuts, or a nagging hunger soon after eating.
One sign doctors take seriously is darkened, velvety skin around the neck, armpits or knuckles. This is called acanthosis nigricans, and it can hint at insulin resistance. If you have spotted patches like these, it is worth a conversation with your doctor. These prediabetes symptoms are gentle whispers, not loud alarms. So please do not wait for a dramatic sign before getting checked.
What Are the Symptoms of Prediabetes in Females?
Women can have an extra clue. If you were diagnosed with gestational diabetes during pregnancy, your risk of prediabetes later in life goes up. Women with polycystic ovary syndrome, or PCOS, also face a higher chance of insulin resistance. Beyond that, the symptoms of prediabetes in females are much the same as in men, tiredness, increased thirst, frequent urination, and unexplained weight changes. The signals are quiet either way, which is why testing matters more than waiting.
What Causes Prediabetes?
At its heart, prediabetes comes down to insulin not working well. But why does that happen? A mix of reasons. Extra weight, especially around the belly, is a big one. Fat stored around your tummy makes your cells more resistant to insulin. A lifestyle heavy on sitting and light on movement adds to it. So does a diet full of refined carbs, fried snacks, sugary drinks and sweets, the very things many of us love at festivals and family functions.
Family history plays its part too. If your parents or siblings have type 2 diabetes, your own risk climbs. Age matters, with risk rising after 35 or so, though we are now seeing this pre diabetic condition in younger Indians far too often. Poor sleep and long-term stress quietly push blood sugar up as well.
Who is Most at Risk?
You should be extra watchful if you are overweight, carry weight around your waist, or have a family history of diabetes. The same goes if you have high blood pressure, abnormal cholesterol, PCOS, or a past history of gestational diabetes. South Asians, including us Indians, tend to develop insulin resistance at a lower body weight than many other populations. So even a "normal looking" build does not fully rule you out.
How is Prediabetes Diagnosed?
This is where a simple blood test does the talking. You cannot diagnose prediabetes by how you feel. You need numbers. Three tests are commonly used, and this quick table shows where you stand.
Fasting blood sugar: below 100 mg/dL is normal, 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or above indicates diabetes.
HbA1c: below 5.7% is normal, 5.7% to 6.4% indicates prediabetes, and 6.5% or above indicates diabetes.
OGTT (2-hour): below 140 mg/dL is normal, 140 to 199 mg/dL indicates prediabetes, and 200 mg/dL or above indicates diabetes.
The HbA1c is handy because it shows your average sugar over the past two to three months, not just one morning. At Unipath, these tests are quick and straightforward. If you are over 35, overweight, or have a family history, getting screened even once a year is a smart habit.
Can Prediabetes Be Reversed?
Yes, and this is the part I love telling patients. Can prediabetes be reversed? In many cases, absolutely. The landmark research here is the Diabetes Prevention Program, backed by the National Institutes of Health. It found that modest lifestyle changes cut the risk of prediabetes turning into diabetes by around 58%. Losing just 5 to 7% of your body weight, that is roughly 4 to 5 kilos for someone weighing 70 kilos, made a real difference. So no, you are not helpless here. Small, steady changes can nudge your blood sugar back towards normal.
What Should a Prediabetes Diet Look Like?
Let me be honest, there is no magic food. A good prediabetes diet is really just balanced, home-style eating with a few smart swaps. Fill more of your plate with vegetables, dals, and fibre-rich foods. Choose whole grains like whole wheat roti, brown rice or millets such as bajra and jowar over polished white rice and maida. Bring in some protein at each meal, whether that is eggs, paneer, curd, sprouts or chicken. It keeps you full and steadies your sugar.
Go easy on the obvious culprits, sugary tea, cold drinks, packaged biscuits, and that second helping of gulab jamun. You do not have to give up your favourite foods forever. Just make them an occasional treat rather than a daily habit. Watch your portions, eat slowly, and try not to skip meals only to overeat later.
What Are the Treatment Options for Prediabetes?
For most people, treatment is not about medicines at all. Lifestyle is the real medicine here. When we talk about pre diabetes symptoms and treatment, movement sits right at the centre. Aim for about 30 minutes of activity on most days. A brisk walk after dinner, cycling, swimming, or even dancing to a few songs counts. Add a little strength work if you can. Along with that, better sleep and lower stress help more than people expect.
Sometimes, doctors do prescribe a medicine called metformin, especially for younger patients or those at very high risk. That decision is best made with your doctor, based on your test results and overall health. The heart of prediabetes treatment, though, stays the same, eat well, move more, sleep enough, and get tested regularly.
When Should You See a Doctor?
If you are above 35, overweight, or have diabetes in the family, please get your blood sugar checked, even if you feel fine. If you have noticed constant thirst, frequent urination, unusual tiredness or those dark skin patches, do not brush them off. A single blood test can give you clarity. And clarity, in this case, is power. The sooner you know where you stand, the more you can do about it.
