About World Diabetes Day
World Diabetes Day is marked on 14 November every year, and in 2026 it falls on Saturday, 14 November 2026. The International Diabetes Federation and WHO started it in 1991, and the United Nations recognised it in 2006. The date is Frederick Banting's birthday, the co-discoverer of insulin. In India the ICMR-INDIAB survey, published in 2023, estimated 101 million adults with diabetes and 136 million more with prediabetes.
In India this date is already busy. Schools are running Children's Day programmes on 14 November, and the diabetes camp in the same town gets half the attention. That is a pity, because the thing the day asks for takes ten minutes and a finger prick.
Why is World Diabetes Day on 14 November?
The date is the birthday of Sir Frederick Banting, who was born on 14 November 1891 and who, with Charles Best, worked out how to extract and use insulin in 1922. Before that, a diagnosis of type 1 diabetes in a child was close to a death sentence.
The International Diabetes Federation and WHO started the day in 1991, when diabetes cases were climbing and no global campaign existed. The United Nations General Assembly passed Resolution 61/225 by consensus in December 2006, and the first official UN observance followed in 2007. The blue circle you see on posters was drawn for that campaign in 2006: a circle for wholeness, in the blue of the United Nations flag.
IDF now sets the theme in two-year blocks. The theme for 2026 and 2027 is "Early action on diabetes", which pushes for earlier diagnosis and less stigma. The reason is in IDF's own numbers: 589 million adults worldwide were living with diabetes in 2024, and about 252 million of them did not know it.
How many people in India have diabetes?
The ICMR-INDIAB survey, a national study of more than 1.1 lakh adults published in 2023, estimated that 11.4 per cent of Indian adults have diabetes, roughly 101 million people, and that another 15.3 per cent, about 136 million, have prediabetes, which means blood sugar high enough to be a warning but not yet diabetes.
WHO's India office adds the part that matters most for the day: more than half of people with diabetes in India do not know they have it. It also notes that diabetes raises the risk of heart attack and stroke by two to three times, and can damage nerves, eyes and kidneys.
The survey also showed that the map is uneven, and that the old assumption of a city disease no longer holds. Rural India is catching up fast, especially on prediabetes.
| Measure | Lowest state in the survey | Highest state in the survey |
|---|---|---|
| Diabetes in adults | Uttar Pradesh, 4.8% | Goa, 26.4% |
| Prediabetes in adults | Mizoram, 6.8% | Sikkim, 31.3% |
The same study found high blood pressure in 35.5 per cent of Indian adults and abdominal obesity, meaning fat around the waist, in 39.5 per cent. These travel together, which is why one camp usually checks blood pressure and sugar on the same table.
Under the National Programme for Prevention and Control of Non-Communicable Diseases, running since 2010, district NCD clinics give free tests and free medicines, and health workers screen people aged 30 and above in their own villages and wards.
What are the warning signs, and what should you do on the day?
- Know the common signsPassing urine often, especially at night. Thirst that does not settle. Losing weight without trying. Cuts and boils that heal slowly. Blurred vision. Constant tiredness.
- Get tested if you are 30 or olderA fasting blood sugar or HbA1c test at any government health centre. Free under NP-NCD screening, and cheap at most labs.
- Get tested earlier if there is family historyA parent or sibling with type 2 diabetes moves the age down. So does a high waist measurement.
- Ask about pregnancy testingBlood sugar is checked during antenatal visits, because diabetes that starts in pregnancy needs treatment and usually settles after delivery.
- Check the feetPeople with diabetes should look at the soles of their feet daily, since nerve damage can hide a wound until it turns serious.
Type 1 diabetes, the kind that usually begins in childhood, is not caused by diet and is not prevented by any lifestyle change. Children with type 1 need insulin every day for life. Saying so plainly matters, because families of these children spend a lot of energy correcting the assumption that someone ate too much sugar.
Etiquette: what not to do around a relative with diabetes
Do
- Offer fruit, nuts or dry snacks alongside the sweets at a family function.
- Ask once what they can eat, then stop asking.
- Make the walk social. "Come with me for a round" works better than a warning.
- Treat insulin injections and finger pricks as ordinary, especially in front of children.
Avoid
- Don't gift a box of mithai to someone with diabetes, however polite it feels.
- Don't say "one piece won't hurt" or push food at a wedding.
- Don't recommend stopping medicines for a herbal cure you read about.
- Don't discuss someone's weight in front of others and call it concern.
- Don't tell a child with type 1 diabetes that they brought it on themselves.
What to write on World Diabetes Day
Happy World Diabetes Day, Papa. Your 6 am walks have outlasted all my gym memberships. Proud of you.
Heard about the diagnosis. It's a lot at the start and it does get routine. I'm around if you want to talk food, doctors or nothing at all.
Happy World Diabetes Day. Lunch walk today? Apparently ten minutes after eating is worth more than an hour of good intentions.
Thinking of you today. The counting, the injections, the night checks, none of it is small. You are doing it beautifully.
World Diabetes Day today. Free sugar tests at the government centre. More than half of people with diabetes in India don't know they have it, so let's all just go and find out.
Wishing you a happy World Diabetes Day. I'm bringing fruit this Sunday, not sweets, and I want a full report on the walking.
Thank you for the patience with every repeated question about diet charts. Happy World Diabetes Day.

How to wish someone on World Diabetes Day
A good World Diabetes Day message is affectionate and practical, never preachy. For a relative living with diabetes, praise the routine rather than the numbers on the meter, and avoid any joke about sweets. For everyone else, the useful nudge is a blood sugar test, since WHO India says more than half of people with diabetes do not know they have it. In gifting season, offer fruit, nuts or a walk instead of a box of mithai.

It is the birthday of Sir Frederick Banting, born on 14 November 1891, who worked with Charles Best to discover how insulin could be used to treat diabetes in 1922. The International Diabetes Federation and WHO chose his birthday when they began the day in 1991.
What is the theme of World Diabetes Day?
The International Diabetes Federation sets themes in two-year blocks. The theme for 2026 and 2027 is "Early action on diabetes", which focuses on diagnosing diabetes earlier, cutting the risk of complications and reducing stigma.

What should I gift someone with diabetes during the festive season?
Skip mithai. Fresh fruit, unsalted nuts, good tea or coffee, a walking accessory or anything non-edible works better. If you are unsure, ask them once rather than guessing, and never push food at a function.
What is the blue circle on World Diabetes Day posters?
It is the global symbol for diabetes, created in 2006 for the campaign that won United Nations recognition for the day. The circle stands for wholeness and unity, and the blue is the blue of the UN flag. Buildings and offices are lit in blue on 14 November, and people wear blue circle pins.
Is diabetes in children caused by eating too much sugar?
No. Type 1 diabetes, the kind that usually starts in childhood, happens when the body stops making insulin, and it is not caused by diet or by anything the child or family did. Children with type 1 need insulin every day for life.
