Type 1 diabetes presenting with weight loss ('dimagrimento'), thirst ('polidipsia'), and frequent urination ('poliuria') is a triad Italian GPs are trained to recognise. Italy has about 300,000 type 1 diabetic patients and 3.5 million type 2. The Italian Society of Diabetology ('SID') runs awareness campaigns. Newly diagnosed diabetics in Italy are enrolled in comprehensive diabetes management programmes through the SSN.
