He hit the gym four times a week, ate what he called "clean," and hadn't seen a doctor in three years because, frankly, there was no reason to. At 34, Arjun looked the picture of health. Then a routine corporate health check flagged an HbA1c of 7.2 - well into diabetic range. He hadn't felt a thing.

His story is not unusual. Across India, endocrinologists are seeing a quiet but telling shift: elevated blood sugar is increasingly being diagnosed in people who, by every visible measure, appear to be doing fine. Young professionals. Regular walkers. People with no family history of weight issues. People who would be the last ones anyone would flag.
This growing pattern of "invisible" high blood sugar is exactly the gap that awareness campaigns are now trying to close.

Gyaan by Ganesh - Making India Win Over Diabetes is an awareness initiative by Sun Pharma, in partnership with the American Diabetes Association, focused on helping Indians better understand, prevent, and manage diabetes through expert backed information.

When The Body Doesn't Send A Memo

One of the most persistent myths around diabetes is that it announces itself through obvious weight gain, visible fatigue, or a clearly unhealthy lifestyle. In clinical practice, that is rarely how it works.

When people picture someone with high blood sugar, they tend to imagine a person who's visibly overweight, fatigued, or clearly unwell. But doctors are increasingly diagnosing elevated blood sugar in people who look perfectly healthy from the outside - young professionals, regular gym-goers, even people with a completely normal body weight.
That disconnect, he explains, is exactly why diabetes so often gets caught late.

High blood sugar can quietly build up over years while a person continues to feel energetic and productive. By the time symptoms appear: blurred vision, tingling in the feet, fatigue that doesn't shift, the damage to organs may already be underway.

The Indian Body's Particular Vulnerability

Genetics plays a major role here. A person can maintain a perfectly reasonable weight and still develop insulin resistance, simply because of inherited metabolic tendencies that are disproportionately common among South Asians. Compounding this is a pattern researchers have flagged for years: many South Asians store fat around their internal organs - known as visceral fat - even when they don't look overweight on the outside at all.

The numbers back this up starkly. According to the ICMR-INDIAB study - a nationwide survey published in The Lancet Diabetes & Endocrinology - India is home to over 101 million people living with diabetes, making it the world's diabetes capital. Another 136 million Indians are estimated to be in the prediabetic range, many of them undiagnosed and, crucially, unsuspecting.

"High blood sugar is often called a 'silent condition' because many people look and feel perfectly healthy despite having elevated glucose levels. Don't rely on symptoms alone. Routine health check-ups and blood sugar testing are the most effective ways to detect diabetes early and prevent long-term complications," Dr Rajendra Patel, Diabetologist, Shreeji The Diabetes Clinic, Vadodara.
