World Diabetes Day - 14 November

World Diabetes Day raises global awareness of diabetes - its escalating rates around the world and how to prevent the illness in most cases. Started by the International Diabetes Federation (IDF) and WHO (World Health Organization), the Day is celebrated on 14 November to mark the birthday of Frederick Banting who, along with Charles Best, was instrumental in the discovery of insulin in 1922, a life-saving treatment for diabetes patients.WHO estimates that more than 180 million people worldwide have diabetes, according to 2005 figures. This number is likely to more than double by 2030 without intervention. Almost 80% of diabetes deaths occur in low and middle-income countries.

WHAT IS DIABETES?
Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin, or alternatively, when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar. Hyperglycaemia, or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels.
Type 1 diabetes (previously known as insulin-dependent or childhood-onset) is characterized by a lack of insulin production. Without daily administration of insulin, Type 1 diabetes is rapidly fatal.
Symptoms include excessive excretion of urine (polyuria), thirst (polydipsia), constant hunger, weight loss, vision changes and fatigue. These symptoms may occur suddenly.
Type 2 diabetes (formerly called non-insulin-dependent or adult-onset) results from the body’s ineffective use of insulin. Type 2 diabetes comprises 90% of people with diabetes around the world, and is largely the result of excess body weight and physical inactivity.
Symptoms may be similar to those of Type 1 diabetes, but are often less marked. As a result, the disease may be diagnosed several years after onset, once complications have already arisen.
Until recently, this type of diabetes was seen only in adults but it is now also occurring in obese children.
Gestational diabetes is hyperglycaemia which is first recognized during pregnancy.
Symptoms of gestational diabetes are similar to Type 2 diabetes. Gestational diabetes is most often diagnosed through prenatal screening, rather than reported symptoms.
Impaired Glucose Tolerance (IGT) and Impaired Fasting Glycaemia (IFG) are intermediate conditions in the transition between normality and diabetes. People with IGT or IFG are at high risk of progressing to type 2 diabetes, although this is not inevitable.

WHO ACTIVITIES TO PREVENT AND CONTROL DIABETES
WHO aims to stimulate and support the adoption of effective measures for the surveillance, prevention and control of diabetes and its complications, particularly in low and middle-income countries. To this end, WHO:
- Provides scientific guidelines for diabetes prevention;
- Develops norms and standards for diabetes care;
- Builds awareness on the global epidemic of diabetes; including partnership with the International Diabetes Federation in the celebration of World Diabetes Day (14 November);
- Conducts surveillance of diabetes and its risk factors.

The WHO Global Strategy on Diet, Physical Activity and Health complements WHO's diabetes work by focusing on population-wide approaches to promote healthy diet and regular physical activity, thereby reducing the growing global problem of overweight and obesity. The Strategy calls upon all stakeholders to take action at the global, regional and local levels and aims to lead to a significant reduction in the prevalence of diabetes and other chronic diseases.
WHO's work on diabetes is integrated into the overall WHO chronic disease prevention and control framework of the Department of Chronic Diseases and Health Promotion. The strategic objectives of the Department are to raise awareness about the global epidemic of chronic diseases; create healthy environments, especially for poor and disadvantaged populations; slow and reverse trends in common chronic disease risk factors such as unhealthy diet and physical inactivity; and prevent premature deaths and avoidable disability due to major chronic diseases.
