India has 136 million people with pre-diabetes — and most do not know it. Pre-diabetes is a condition where blood sugar levels are higher than normal but not yet high enough for a type 2 diabetes diagnosis. Without intervention, pre-diabetes progresses to type 2 diabetes within 5-10 years in most cases.
The tragedy: pre-diabetes is completely reversible with lifestyle changes — but only if caught early enough.
"Pre-diabetes is not a warning — it is an opportunity. The last exit before the highway of diabetes begins." — Dr. Anurag Singh
Indians develop insulin resistance at significantly lower BMI levels than Western populations. An Indian at BMI 23 may already be metabolically at risk — whereas Western guidelines typically flag risk only at BMI 25+. This means millions of "normal weight" Indians are already in pre-diabetic territory.
If you consistently feel extremely tired or sleepy after meals — especially carbohydrate-heavy Indian meals — this may indicate blood sugar dysregulation. When cells cannot effectively use glucose for energy (insulin resistance), post-meal energy crashes result.
⚠️ Watch for: Needing to sleep or rest after lunch or dinner; feeling drained within 1-2 hours of eating.
Higher blood sugar levels cause the kidneys to work harder to filter excess glucose — leading to more frequent urination and consequently more thirst. Many pre-diabetics notice they are waking up at night to urinate or drinking unusually large amounts of water.
This is one of the most visible and underrecognised signs of pre-diabetes in Indians. Dark, velvety skin patches — typically appearing on the back of the neck, armpits, groin, or knuckles — are caused by excess insulin driving skin cell growth. This sign is especially common in Indian and South Asian populations.
⚠️ Check: Look at the back of your neck and armpits for darkening or thickening of the skin — not from sun exposure.
High blood sugar impairs circulation and the immune response, slowing the body's natural healing ability. If minor cuts, bruises, or skin irritations seem to take longer than usual to heal, this warrants attention.
Fluctuating blood sugar levels can cause the lens of the eye to swell and change shape, leading to intermittent blurry vision. This is different from needing glasses — it comes and goes, often correlating with meals or times of day.
Elevated blood sugar damages small nerve fibres over time — a condition called peripheral neuropathy. Early signs include tingling, numbness, or a "pins and needles" sensation in the extremities, particularly feet. Many people dismiss this as poor circulation or sleeping position — but in pre-diabetics, it reflects early nerve damage.
High blood sugar creates an ideal environment for fungal and bacterial growth. Frequent urinary tract infections (UTIs), fungal skin infections (especially in skin folds), or recurring oral thrush may indicate chronically elevated blood sugar levels.
⚠️ Particularly notable in women: Recurring vaginal yeast infections or frequent UTIs with no other obvious cause.
Multiple large-scale studies, including the Indian Diabetes Prevention Programme (IDPP), have demonstrated that pre-diabetes can be reversed with structured lifestyle intervention — achieving 58% reduction in progression to diabetes through diet and exercise alone. You have the power to change this trajectory.
