- It was created in 1991 by the International Diabetes Federation with WHO support and became an official UN day in 2006.
- The 2026 theme listed by WHO is "Early action on diabetes."
- In the US, November is National Diabetes Month (Diabetes Awareness Month).
Why November 14?
World Diabetes Day falls on the birthday of Sir Frederick Banting, who, with Charles Best, discovered insulin in 1921 — turning type 1 diabetes from a fatal disease into a manageable one. The International Diabetes Federation (IDF) launched the day in 1991 with the World Health Organization, and the United Nations recognized it officially in 2006.
The blue circle
The IDF's blue circle is the global symbol for diabetes awareness. The circle stands for unity, and the blue reflects the sky and the UN flag. On November 14, landmarks around the world light up in blue.
2026 theme: early action
WHO lists "Early action on diabetes" as the theme for World Diabetes Day on 14 November 2026. Early action fits the facts: in the US alone, about 11 million adults with diabetes don't know they have it, and 115 million have prediabetes.
Diabetes Awareness Month in the US
November is National Diabetes Month in the United States, with campaigns from organizations such as the American Diabetes Association and government health agencies encouraging screening, education, and support.
Simple ways to take part
- Know your numbers: ask for an A1C or fasting glucose test, especially if you're 35 or older.
- Learn the signs: read about diabetes symptoms and share them.
- Take a walk: organize a blue-themed walk — 150 minutes a week of activity lowers type 2 risk.
- Wear blue or the blue circle and share why it matters to you.
- Support someone living with diabetes — offer to join a healthy meal or a checkup.
- Learn the plate method: try a week of meals using the diabetes plate method.
Check your risk this November
Risk factors include age over 35, family history, overweight, inactivity, high blood pressure, and a history of gestational diabetes. If any apply, make November the month you get tested.
