India has long been called the “Diabetes Capital of the World.” According to a 2023 ICMR-INDIAB study, over 100 million Indians are living with diabetes, and another 140 million are pre-diabetic—meaning they’re at high risk of developing the condition soon.

Contrary to popular belief, diabetes isn’t just linked to obesity. Even people who appear thin can be metabolically unhealthy and may develop diabetes. More than 70% of Indians have poor metabolic health, meaning their blood sugar, cholesterol, and blood pressure are not well-controlled.

Diabetes: No Longer Just an Old-Age Disease

Experts warn that diabetes is increasingly affecting young adults, teenagers, and even children. According to Dr. Pankaj Agarwal (Consultant Diabetologist, Hormone Care & Research Centre, Ghaziabad), Dr. Subodh Banjal (Head, Endocrinology, Sri Aurobindo Medical College, Indore), and Dr. Balram Sharma (Professor, Endocrinology, SMS Medical College, Jaipur), the shift in age group is primarily due to lifestyle and dietary changes.

Modern youth lead sedentary lives, spend excessive time on screens, and consume junk food regularly. The COVID-19 pandemic worsened these habits, leading to a spike in obesity and early-onset Type 2 diabetes among people as young as 15–25 years—an age group previously considered low-risk.

Why Are Young People Developing Diabetes?

• Poor diet and inactivity: High-calorie foods and low physical activity reduce insulin sensitivity.

• Genetic factors: Family history increases the risk.

• Stress and poor sleep: Both can disrupt hormone balance.

• Childhood obesity: Rising rates are a major contributor.

If lifestyle habits aren’t corrected early, diabetes can develop even in youth.

5 Key Warning Signs Your Body Gives

While Type 1 diabetes often shows early symptoms, Type 2 diabetes may remain hidden for years. According to doctors, here are five important warning signs:

1. Frequent urination and excessive thirst

2. Unexplained fatigue or weakness

3. Sudden weight loss

4. Itching or redness in private parts

5. Slow-healing wounds or blurred vision

If any of these signs appear, consult a doctor and get your blood sugar levels checked immediately.

Tests to Detect Diabetes

Doctors recommend three main tests for diagnosis:

1. Fasting Blood Glucose:

   • Normal: below 100 mg/dL

   • Prediabetes: 100–125 mg/dL

   • Diabetes: above 126 mg/dL

2. Post-Prandial (After-Meal) Glucose:

   • Normal: below 140 mg/dL

   • Prediabetes: 140–199 mg/dL

   • Diabetes: 200 mg/dL or above

3. HbA1c (Average Blood Sugar for 3 Months):

   • Normal: below 5.7%

   • Prediabetes: 5.7–6.3%

   • Diabetes: above 6.4%

For accurate results, avoid random glucose or urine sugar tests. Instead, follow the 75-gram glucose tolerance test under medical supervision.
