Diabetes in India is no longer confined to older adults. It is increasingly affecting younger populations, including children and adolescents, making early detection more urgent than ever. According to the International Diabetes Federation, India had an estimated 89.8 million adults living with diabetes in 2024. The ICMR-INDIAB study places adult prevalence at 11.4per cent, with another 15.3per cent classified as prediabetic. Among children and adolescents, government-linked data highlights a significant burden, with over 22.9 lakh individuals affected by type 1 diabetes globally in India’s context.
A Silent Disease With Early Clues
One of the biggest challenges with diabetes is that it often progresses quietly. While the condition is commonly associated with symptoms like excessive thirst and frequent urination, early warning signs tend to appear in less obvious ways particularly in the legs, feet and brain.
A Mayo Clinic review notes that diabetic neuropathy often begins in the lower limbs, leading to numbness, tingling, burning sensations, muscle weakness and slow-healing foot ulcers. These symptoms may appear mild initially but can indicate ongoing nerve damage caused by prolonged high blood sugar levels.
Experts Urge Attention to Subtle Symptoms
Dr. Bhupesh Kumar Mansukhani, Director – Neurology at Neuromet Wellness Care and Diagnostics, Gurgaon, said that early neurological changes linked to diabetes are often overlooked because they appear minor at first.
He said, “Unusual sensations in the legs such as tingling, numbness or burning, as well as subtle cognitive changes, can often be the earliest indicators of diabetic nerve involvement. These symptoms are frequently ignored or attributed to fatigue or lifestyle factors, but in individuals with risk factors like genetic predisposition or unhealthy habits, they may signal the beginning of a more serious metabolic disorder. Recognising these early warning signs is critical because timely intervention can significantly reduce the risk of long-term complications.”
He also stressed the importance of prevention and lifestyle management. He added, “A balanced diet, regular physical activity, maintaining a healthy weight and managing stress are fundamental to preventing the progression of diabetes and its complications. Early identification of symptoms allows for timely medical intervention, which can slow or even prevent nerve damage from advancing to more severe stages.”
Brain Fog, Fatigue and Hidden Risks
Diabetes does not only affect the limbs, it can also impact brain function in subtle but significant ways. Dr. Gaurav Batra, Neurosurgeon (Brain & Spine) at Max Hospital, Vaishali, explained that fluctuating blood sugar levels can influence cognitive health, often presenting as symptoms that are easy to dismiss.
He said, “Symptoms such as persistent headaches, lack of focus, memory lapses and unexplained fatigue may not immediately be linked to diabetes, but they can reflect underlying fluctuations in blood glucose levels. These manifestations are often mistaken for stress or routine exhaustion, which delays proper diagnosis and management. However, in many cases, they may be early indicators of prediabetes or diabetes.”
He also emphasised the need for timely medical attention when such symptoms persist.
He added, “If individuals experience ongoing numbness in the legs, excessive fatigue, difficulty concentrating or wounds that are slow to heal, they should seek medical evaluation without delay. More serious warning signs such as sudden confusion, extreme fatigue or infections in the legs and feet require immediate attention, as they may indicate advanced complications.”
The Cost of Delayed Diagnosis
Delayed recognition of diabetes continues to be a major issue in India. Many patients begin treatment only after complications have already developed, increasing both health risks and financial burden.
A national representative study found that 38per cent of households with diabetic members face catastrophic health expenditure, while nearly 10per cent are pushed below the poverty line due to out-of-pocket costs. Medicines account for a significant share of these expenses, making early detection and consistent management essential.
A Growing Public Health Challenge
India’s diabetes burden is projected to rise sharply in the coming decades. The International Diabetes Federation estimates that the number of adults living with diabetes in India could increase from 89.8 million in 2024 to 156.7 million by 2050 if current trends continue.
This growing burden highlights the importance of identifying early, often overlooked symptoms before the disease progresses to advanced stages.
Why Early Detection Matters
Doctors emphasise that diabetes-related damage often begins long before visible symptoms appear. By the time classic signs emerge, nerve damage and metabolic complications may already be underway.
For this reason, even mild or seemingly insignificant symptoms especially those affecting the legs, feet or cognitive function should not be ignored. This is particularly important for individuals over 40, those with obesity, or those with a family history of diabetes.
In India, the bigger challenge is not just the disease itself, but the tendency to wait for clear symptoms. Recognising the early warnings can make the difference between prevention and lifelong complications.
