The stage nobody is standing in alone
Before diabetes there is a waiting room, and it is crowded. National surveys count roughly 136 million Indians in the borderline zone alongside about 101 million already diagnosed — which means, in a district like ours, that the borderline group is very likely larger than the diabetic one, and almost entirely unaware of itself. Nothing hurts. Nothing shows. Sugar — sakkarai noi in Tamil, prameham in Malayalam — is discussed in every household here as something that happens at fifty, suddenly, to somebody else’s father. It does not happen suddenly. It is built quietly across ten or fifteen years, and this page is about those years, because they are the only part of the story you can still edit.
“It runs in my family” — where most people start
Almost everyone who reads a page like this was sent here by a relative’s diagnosis. The honest numbers first: with one parent who has type-2 diabetes, lifetime risk sits near thirty percent; with both, near seventy. An Indian study of families where both parents had type-2 found that about six in ten of their grown children already had abnormal glucose when tested — not later, already. That figure frightens people into fatalism, which is exactly the wrong conclusion, because the same research tradition produced the opposite finding: in an Indian trial of high-risk adults, ordinary lifestyle change cut new diabetes by nearly a third. Genes load the gun; the next twenty years decide whether anyone pulls the trigger.
Sixty seconds, then one blood test
Worry is not a plan, and neither is waiting for a symptom. Start with the 60-second diabetes risk score — four questions about age, waist, activity and family history, no needle, no lab, no fee — which is the same scoring method Chennai’s diabetes researchers built for Indian bodies. A high score does not diagnose anything; it tells you the test is now urgent rather than optional.
Then the test itself, because one blood test settles what years of speculation cannot: a fasting sugar, or an HbA1c, which needs no fasting and reads the last three months instead of one morning. Take the report and hold it against the blood sugar levels chart before anyone tells you it is fine.
The word on the report: borderline
Borderline is the most misread word on any lab report in this district. Patients hear it as almost normal, file the paper in the almirah, and return three years later with a diagnosis. It is neither normal nor a sentence. In a Kerala cohort followed over a decade, about sixty percent of people with borderline fasting sugar had become diabetic within ten years — and in an Indian trial, more than half of untreated borderline cases progressed within just three. Read the other way, that is the largest opportunity anyone gets: a warning delivered years before the damage, in writing.
Borderline sugar (prediabetes) — what your numbers mean →HbA1c between 5.7 and 6.4, value by value →
What the body says before the lab does
Sometimes there are signs, and they are read as something else — age, heat, work, weak eyes. Passing urine twice a night, thirst that a tumbler does not settle, hunger an hour after a full meal, wounds that take their time, a tiredness that sleep does not fix. Early signs of diabetes sets them out plainly, including the ones nobody mentions.
And one sign is visible from across a room: a velvety darkening at the back of the neck that no amount of scrubbing removes, often noticed first on a child. It is not dirt and it is not a hygiene failure — it is frequently the earliest visible mark of insulin resistance.
The work that turns it back
Here is the part worth forwarding to the family: prediabetes can be reversed — returned to normal regulation — and the evidence for it in Indian bodies is good. Not by a package, a course or a plant, but by weight that comes off and stays off, meals that stop spiking, and movement that survives December. How to reverse prediabetes covers what the trials actually achieved and how long it took, including the honest part: it can return if the habits do.
Two pages carry the daily practice. The 30 minutes that prevent diabetes is about the walk you will still be doing next year rather than the gym membership you will not, and the ten minutes after a meal that do more than their size suggests. The borderline-sugar food list is written for a rice, idli and kappa coast, not for a magazine’s quinoa: matta versus white, how many idlis, what to do about parotta and payasam, and which swaps genuinely move a number.
Two bodies the rulebook misses
The weighing scale is a poor guardian here. South Asian bodies reach the diabetes risk of a heavyset European at a BMI of about 22 — a build most families would call slim, even underfed — because the fat that matters sits around the organs rather than on the frame. The thin uncle with a paunch and a high HbA1c is not an exception; he is a pattern.
Normal weight, abnormal sugar →
The second miss is a mother. Sugar that appeared during pregnancy usually leaves with the delivery, and the risk stays behind: more than one in five women develop abnormal sugar within a year of a gestational diagnosis. The six-week postpartum test is the single most-skipped test in this practice, at exactly the moment when prevention is cheapest.
Where prevention fails — the other half of this practice
Dr. Ruskin also works in intensive care, which gives this hub an unusual companion: a page-by-page account of what these years lead to when nobody intervenes. Prevention from an ICU doctor is that wing — written not to frighten, but because knowing the destination changes how seriously the road is taken.
Two of its pages belong to everyone reading this one. Diabetes can switch off the chest pain that is supposed to save a life, so a heart attack arrives instead as breathlessness or plain exhaustion — the silent heart attack. And the most preventable admission in this district still begins with a sentence spoken in good faith: I wasn’t eating, so I skipped the insulin — the sick-day rules.
What to do in the next seven days
Take the risk score today; it costs a minute. If you are past thirty-five, or sugar runs in the family, get a fasting sugar or an HbA1c done rather than assuming — and if a previous report said borderline, repeat it now rather than next year. Measure your waist honestly, at the navel, without pulling in. Add a ten-minute walk after the largest meal of your day, which is the smallest change with the best attendance record. And if the report has already crossed the line, the diabetes practice is where the rest of the work lives — targets, food, medicines and reviews that keep the numbers honest.

Frequently asked questions
They are the same thing said two ways. Borderline sugar is what families here call it; prediabetes is the word on the report. It means fasting glucose between 100 and 125, post-meal between 140 and 199, or an HbA1c of 5.7 to 6.4 — above normal regulation, below the diabetes line, and still reversible.
Largely, yes. Family history raises the risk substantially — with one diabetic parent the lifetime risk is roughly thirty percent, with both around seventy — but inheritance sets the odds, not the outcome. An Indian trial showed that steady lifestyle change cut new diabetes by nearly a third among people already at high risk.
Yes, and that is precisely the point. The borderline years produce no thirst, no weight loss and no tiredness worth reporting — feeling perfectly well is the normal experience of this stage, not evidence against it. If you are past thirty-five, or sugar runs in the family, the test is the only honest answer available.
A fasting blood sugar or an HbA1c, and either can be done at PPK Hospital's laboratory or any reliable lab near you. HbA1c has one practical advantage: no fasting is needed, so it survives a working morning. A single borderline result should be repeated before it is treated as a verdict.
For many people, yes — this is one of the few genuinely hopeful sentences in diabetes medicine. Prediabetes can be returned to normal regulation with weight loss, movement and portion change sustained over months. It can also come back if the changes stop, which is why the yearly test continues even after a normal report.
