This page is health information, not a diagnosis and not medical advice.
It is written to help you decide whether to get checked, not to replace
the doctor who does the checking.
How common it is
India has an estimated 136 million people with prediabetes and 101 million with diabetes, a weighted prevalence of 15.3% and 11.4% respectively (ICMR-INDIAB-17 national study, published in The Lancet Diabetes & Endocrinology, 2023). Abdominal obesity, the strongest single predictor, affects 39.5% of adults.
The number that matters is the first one. Prediabetes is a warning, not a diagnosis, and the population carrying it is larger than the population that has already crossed over.
Why Indian bodies cross the line earlier
South Asians develop insulin resistance at lower body weights than European populations, and carry more of their fat viscerally, around the organs rather than under the skin. Visceral fat is metabolically active and drives insulin resistance directly.
This is why Healthness+ scores BMI against the Indian consensus thresholds rather than the international ones. Overweight begins at a BMI of 23, not 25, and obesity at 25, not 30. A person told they are a “normal weight” under the WHO chart can be well inside the risk range under the Indian one.
What is actually happening
Muscle, liver and fat cells stop responding properly to insulin. The pancreas compensates by producing more of it. For years, often a decade, blood glucose stays near normal because the extra insulin is doing the work, which is precisely why a single fasting glucose reading can look reassuring while the underlying problem is well advanced.
Prediabetes is the stage where that compensation starts to fail. Weight around the middle, energy crashes after meals, skin tags, darkened patches at the neck or armpits, and a family history of diabetes are all worth taking seriously together, even when each one on its own looks minor.
What tends to move the needle
The interventions with the strongest evidence are unglamorous and behavioural rather than pharmacological:
- Resistance training. Working muscle increases glucose uptake independently of insulin. The effect on insulin sensitivity is measurable for a day or two after a single session.
- Walking after meals. Ten to fifteen minutes after a main meal blunts the post-meal glucose rise more reliably than the same walk taken at another time of day.
- Meal order. Eating vegetables and protein before the rice or roti, rather than alongside it, measurably lowers the post-meal glucose and insulin response to the same food.
- Sleep. Short or broken sleep produces insulin resistance in healthy people within days. It is not a soft factor here.
- Liquid sugar. Sweetened chai, juice, flavoured yoghurt and soft drinks deliver glucose faster than solid food and are usually the easiest single change to make.
Where the Healthness+ assessment fits
The Healthness+ Health Risk Assessment scores metabolic signals alongside sleep, stress, gut and activity, because prediabetes rarely arrives on its own. A raised metabolic score sitting next to a poor sleep score is a different problem from the same score with good sleep, and it needs a different plan.
Common questions
Can prediabetes be reversed?
Prediabetes is considered modifiable, and a substantial proportion of people return to normal glucose regulation through sustained changes to diet, activity, weight and sleep. It is not guaranteed, and it depends on how long the insulin resistance has been developing and on individual factors. What is well established is that the progression to type 2 diabetes is not inevitable.
Does prediabetes have symptoms?
Usually none. That is the defining problem with it. Some people notice fatigue after meals, increased thirst, weight gain around the abdomen, or darkened skin at the neck and armpits, but the majority have no symptom that would send them to a doctor.
What blood test detects prediabetes?
Fasting plasma glucose, HbA1c, or an oral glucose tolerance test, the criteria are set by the WHO and your doctor decides which applies. A risk assessment like ours does not replace those tests; it tells you whether and how urgently to go and get them done.
I am not overweight. Can I still have prediabetes?
Yes. Insulin resistance in South Asians frequently appears at body weights that look unremarkable, because the fat distribution matters more than the total. Waist measurement and metabolic markers are more informative than the number on the scale.
