Type 1 diabetes (previously known as insulin-dependent, juvenile or childhood-onset) is characterized by deficient insulin production and requires daily administration of insulin.
Until recently, this type of diabetes was seen only in adults but it is now also occurring increasingly frequently in children. As a result, the disease may be diagnosed several years after onset, after complications have already arisen. Symptoms may be similar to those of type 1 diabetes but are often less marked. This type of diabetes is largely the result of excess body weight and physical inactivity. More than 95% of people with diabetes have type 2 diabetes. Type 2 diabetes (formerly called non-insulin-dependent, or adult-onset) results from the body’s ineffective use of insulin. In lower-middle-income countries, the mortality rate due to diabetes increased 13%.īy contrast, the probability of dying from any one of the four main noncommunicable diseases (cardiovascular diseases, cancer, chronic respiratory diseases or diabetes) between the ages of 30 and 70 decreased by 22% globally between 20. Another 460 000 kidney disease deaths were caused by diabetes, and raised blood glucose causes around 20% of cardiovascular deaths (1).īetween 20, there was a 3% increase in age-standardized mortality rates from diabetes. In 2019, diabetes was the direct cause of 1.5 million deaths and 48% of all deaths due to diabetes occurred before the age of 70 years.
In 2014, 8.5% of adults aged 18 years and older had diabetes. Hyperglycaemia, also called raised blood glucose 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. Insulin is a hormone that regulates blood glucose. Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces.
