Diabetes is a serious, chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces.

There are three major types of diabetes: type 1 diabetes which is the most frequent among children and adolescents; type 2 diabetes which is the most frequent among adults and it is linked to obesity or overweight, lack of physical activity and poor nutrition; and gestational diabetes which is a complication of pregnancy that affects an estimated 10% of pregnancies globally.
