The epidemic of the 21st century - this is how diabetes can be described in a nutshell, especially its incidence in recent years and the tendency to increase the number of people suffering from it in the future. Over the last 35 years, the number of people suffering from diabetes has increased by almost 50%. Every year, more people die from diabetes in the world than from AIDS, malaria and tuberculosis combined. In Poland, as many as 2% of Poles die annually due to diabetic complications. What is worse, about 30% of patients do not know that they have the disease at all.
