Half of diabetics in Bulgaria are undiagnosed and considered "healthy"

There are about 770,000 Bulgarians with diabetes, but only half of them know their diagnosis. The main risk factor is prediabetes, a condition in which blood sugar levels are higher than normal-between 5.7 and 6.4 mmol/L. Diabetes development can be prevented with the necessary lifestyle changes. Other risk factors include obesity, high blood pressure and advancing age.
