Key Facts

Historical Background

• World Diabetes Day was established in 1991 by the International Diabetes Federation (IDF) and the World Health Organization (WHO).
• It was introduced in response to the increasing global burden of diabetes and the need for international awareness.
• The date, 14 November, was selected to commemorate the birth anniversary of Sir Frederick Banting, who was born on 14 November 1891.
• Banting, along with Charles Best and other researchers, played a major role in the discovery of insulin in 1921.
• In December 2006, the United Nations General Assembly adopted Resolution 61/225, officially recognising World Diabetes Day as a United Nations Day.
• This recognition highlighted diabetes as a major global public health challenge.
• It encouraged governments, international organisations and civil society to strengthen diabetes prevention, treatment and awareness programmes.
• The blue circle is the globally recognised symbol of diabetes awareness.
• Blue represents the colour of the United Nations flag.
• The circle symbolises unity among the global community in the fight against diabetes.
• It represents the collective commitment to improving diabetes awareness, prevention and care.

What is Diabetes?

• Diabetes mellitus is a chronic metabolic disease characterised by elevated blood glucose (blood sugar) levels.
• It occurs when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces.
• Insulin is a hormone produced by the beta cells of the pancreas.
• It helps glucose enter the body's cells, where it is used to produce energy.
• When insulin production or utilisation is impaired, glucose accumulates in the bloodstream, leading to hyperglycaemia.

Types of Diabetes

Major Causes and Risk Factors

• Obesity: Excess body fat can increase insulin resistance
• Physical Inactivity: Lack of exercise affects glucose metabolism
• Unhealthy Diet: Excessive consumption of processed foods and sugary drinks can contribute to metabolic problems
• Family History: Genetic factors can increase susceptibility
• High Blood Pressure: Often associated with insulin resistance and metabolic risk
• Smoking: Increases the risk of Type 2 diabetes and cardiovascular complications
• Gestational Diabetes History: Increases the mother's future risk of Type 2 diabetes

Symptoms of Diabetes

• Frequent Urination (Polyuria): Increased glucose levels can cause excessive urination.
• Excessive Thirst (Polydipsia): Frequent urination can lead to dehydration and increased thirst.
• Increased Hunger (Polyphagia): The body's cells may not receive sufficient energy.
• Unexplained Weight Loss: The body may start breaking down fat and muscle for energy.
• Fatigue: High or poorly controlled blood glucose can cause tiredness.
• Blurred Vision: Changes in blood glucose can affect the eye's lens.
• Slow Wound Healing: Diabetes can affect circulation and immune function.

Major Complications of Diabetes

• Cardiovascular Diseases: Increases the risk of heart attack and stroke
• Diabetic Retinopathy: Damages blood vessels in the retina and may cause vision loss
• Diabetic Nephropathy: Damages kidneys and may lead to kidney failure
• Diabetic Foot: Can cause ulcers, infections and, in severe cases, amputation
• Oral Health Problems: Increases the risk of gum disease and infections

Global Burden of Diabetes

• Diabetes is one of the fastest-growing public health challenges worldwide.
• According to the IDF Diabetes Atlas 2025, approximately 589 million adults aged 20–79 years were living with diabetes in 2024.
• The number is projected to increase to approximately 853 million by 2050.
• Around 252 million adults were living with undiagnosed diabetes in 2024.
• Diabetes places a significant economic burden on healthcare systems due to long-term treatment and complications. 

Major Government Initiatives in India

• National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD)
  • The programme focuses on the prevention, screening, early diagnosis and management of major non-communicable diseases.
  • Diabetes is one of its major areas of focus.
  • It promotes population-based screening and early identification of individuals at risk.
  • It also supports the strengthening of healthcare services at primary, secondary and tertiary levels.
• Ayushman Bharat: Health and Wellness Centres

  • They focus on screening, prevention and management of non-communicable diseases, including diabetes.
  • They help improve access to healthcare services, particularly in rural and underserved areas.
• National Health Mission (NHM)
  • The National Health Mission supports the delivery of accessible and affordable healthcare.
  • It strengthens healthcare infrastructure, human resources and primary healthcare services.
  • It also supports initiatives related to the prevention and control of non-communicable diseases.
• Fit India Movement
  • Launched on 29 August 2019.
