India today carries one of the heaviest diabetes burden in the world. This is a crisis that is not just driven by genetics, but also by rapid urbanization, sedentary routines, shifting diets, stress, and late diagnosis. With over 101 million Indians currently living with diabetes in India, and 136 million in the pre-diabetic stage, as stated by the latest ICMR estimates, the country is facing an epidemic. This threatens to overwhelm the healthcare system in the coming years. Why Is Diabetes In India Rising So Rapidly?India’s diabetes epidemic is no longer limited to middle-aged adults or people with a family history. Younger Indians, those in their 20s and 30s, are increasingly being diagnosed.According to Dr. Hetashvi Gondaliya, the surge is largely due to “unhealthy dietary habits, physical inactivity, stress, and obesity,” adding that India is witnessing a rise in both Type 2 diabetes and prediabetes among younger people. She emphasizes that early screening, lifestyle modification, and weight management are no longer optional, they are essential.The biggest challenge in India’s diabetes landscape is late diagnosis. Many people discover their condition only after developing complications.Dr. Ankur Gehlot, Additional Director of Diabetes & Endocrinology at CK Birla Hospitals, stresses that early recognition, especially in high-risk groups, can prevent long-term complications. However, experts say that there is still hope. With early screening, community support, technological advances, and sustained lifestyle changes, the trajectory can be reversed. Diabetes, A Silent KillerEndocrinologist Dr. Kalyan Kumar Gangopadhyay describes diabetes as “a silent killer” because its early stages rarely trigger noticeable symptoms. As he puts it, many people assume diabetes only affects blood sugar, but in reality, “it quietly damages the body’s vital systems, from the heart and kidneys to the eyes, nerves, and even sexual health.” He cautions that in men, prolonged, uncontrolled diabetes can lead to erectile dysfunction, nerve damage, and hormonal imbalance. In women, it increases risks of heart disease, bone weakness, and vision problems. What makes it more dangerous is the misconception that diabetes always announces itself.“Another common myth is that early diabetes has obvious symptoms; in reality, up to 80% of people may not notice any signs until serious complications appear,” he explains. This delay in diagnosis is one of the biggest reasons India sees high numbers of kidney failure, amputations, heart disease, and blindness linked to diabetes.Diabetes And Heart, A Connection Most People UnderestimateCardiovascular complications remain the leading cause of death among people with diabetes. Dr. Anjan Siotia, Director of Cardiology at BM Birla Heart Hospital, warns that diabetes affects the heart “in more ways than most people realize.” High blood sugar damages blood vessels, accelerates artery blockages, and raises bad cholesterol (LDL). He advises that diabetic individuals must keep their LDL cholesterol below 2.6 mmol/L, alongside maintaining regular physical activity and a balanced diet.While heart risk is present year-round, he notes that winter months are particularly dangerous. Cold temperatures constrict arteries and increase cortisol levels, forcing the heart to work harder, especially risky for those with diabetes, high blood pressure, or obesity. “We often see a spike in cardiovascular cases during winter,” he stresses.Dr. Siotia explains that diabetes doesn’t just affect large arteries but also small vessels, leading to peripheral vascular disease, kidney problems, retinopathy, stroke, and heart failure.His key message: routine monitoring saves lives. Diabetic patients should complete blood tests on time and get an annual ECG to detect early abnormalities.The Hope, The Innovation, The Awareness, and The EmpowermentFor decades, diabetes care depended heavily on intermittent monitoring and patient self-discipline. But technology is now reshaping diabetes management in ways that reduce burden, improve outcomes, and make daily care more seamless.Endocrinologist Dr. Sanjay Kalra explains that diabetes care is shifting from periodic checks to “continuous, real-time, data-driven management.” According to him, the biggest breakthrough has been the widespread adoption of:Continuous Glucose Monitors (CGMs)These provide real-time readings and trend insights, reducing finger pricks and helping patients and caregivers make timely decisions.AI-enabled platformsThese analyze glucose patterns, diet, physical activity, and medication history, offering predictive insights that help prevent fluctuations rather than react to them.Smart insulin pensThey automatically track dose and timing and remind patients about missed doses through connected apps.Closed-loop insulin pumpsOften described as the closest to an “artificial pancreas,” these pumps automatically increase or decrease insulin delivery using CGM data, even while the patient sleeps.Dr. Kalra emphasizes that these systems reduce the cognitive load of living with diabetes and consistently improve accuracy, treatment satisfaction, and glycemic outcomes. The key, he says, is to individualize the technology based on each patient’s needs and lifestyle.Dr. Kalra notes that peer-support and community-led models are extremely effective, especially in underserved regions where specialist care is limited. He points out that patients participating in peer groups:have better glycemic outcomesask informed questionsmaintain long-term motivationand show improved adherence to medications, diet, and monitoring routinesPatients relate more easily to someone who has “been there,” he says, which makes health information more relatable.Doctors unanimously agree that India must strengthen routine screening for people who:are overweighthave a family history of diabeteslive sedentary lifestyleshave PCOShave high blood pressure or high cholesterolexperience frequent fatigue, excessive thirst, or slow wound healingRegular monitoring, they say, is not optional but foundational.
