World Diabetes Day 2026 is observed on November 14. It is a good day to learn the early signs of diabetes, who is at higher risk and which tests can detect it. India has a very large number of people with diabetes and prediabetes, and many do not know they have it, because early diabetes often causes few or no symptoms.
This guide is general information, not medical advice. Only a doctor can diagnose diabetes and decide on treatment.
World Diabetes Day 2026: Why It Matters in India
A large national study published in 2023 (ICMR-INDIAB) estimated that around 10 crore people in India were living with diabetes, and a much larger number had prediabetes. Because high blood sugar can damage the eyes, kidneys, nerves, heart and blood vessels over time, finding it early gives you a chance to protect your health.
Each year, the International Diabetes Federation and WHO choose a theme for the day. Check the official IDF website for this year's theme and campaign.
Early Signs and Symptoms of Diabetes
| Sign | What you may notice |
|---|---|
| Increased thirst | Feeling thirsty even after drinking water |
| Frequent urination | Passing urine more often, including at night |
| Tiredness | Feeling very tired without a clear reason |
| Blurred vision | Vision that changes or becomes unclear |
| Slow healing | Cuts, sores or infections that take long to heal |
| Unexplained weight loss | Losing weight without trying |
| Tingling or numbness | Pins and needles in the hands or feet |
These symptoms can have other causes, and some people with type 2 diabetes have no symptoms at all. If you notice them, see a doctor and get tested instead of guessing.
Who Is at Higher Risk?
- A parent, brother or sister with diabetes.
- Being overweight, especially with extra fat around the waist. South Asians can develop diabetes at lower body weights than other groups.
- Low physical activity and a diet high in refined carbohydrates and sugary drinks.
- High blood pressure, high cholesterol or a history of heart disease.
- A history of gestational diabetes or polycystic ovary syndrome (PCOS).
- Age. Risk rises with age, and doctors often advise screening from around the early 30s, or earlier if you have other risk factors.
Which Tests Detect Diabetes?
Your doctor may use one or more of these blood tests. The cut-offs below are widely used, but your doctor will interpret your results and may repeat a test to confirm.
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting blood sugar | Below 100 mg/dL | 100 to 125 mg/dL | 126 mg/dL or higher |
| HbA1c | Below 5.7% | 5.7% to 6.4% | 6.5% or higher |
| 2-hour glucose tolerance test | Below 140 mg/dL | 140 to 199 mg/dL | 200 mg/dL or higher |
HbA1c shows your average blood sugar over about three months. A random blood sugar of 200 mg/dL or more with classic symptoms can also point to diabetes. Do not diagnose yourself from one reading or a home glucometer alone.
Healthy Habits That Lower Risk
- Move more: aim for about 150 minutes of moderate activity a week, such as brisk walking, plus some muscle-strengthening exercise.
- Eat balanced meals: include vegetables, whole grains, pulses, nuts and fruit, and cut back on sugary drinks, sweets and deep-fried snacks.
- Watch your weight and waist: even a modest weight loss can reduce risk if you are overweight.
- Sleep well: poor sleep affects blood sugar. See our guide on how to improve your sleep routine.
- Do not smoke, and limit alcohol.
- Get checked: have regular health check-ups, especially if you have risk factors. Build healthy routines with our guide to healthy habits.
If You Already Have Diabetes
- Take medicines exactly as prescribed, and do not stop or change them on your own.
- Check your blood sugar as your doctor advises, and keep a log.
- Have regular check-ups for your eyes, feet, kidneys and blood pressure.
- Learn the signs of very high or very low blood sugar, and seek urgent medical help for confusion, severe weakness, fainting or persistent vomiting.
- Plan festival meals sensibly. Read our guide to Diwali health tips.
