The objective of the work was to assess whether education focused on hypoglycaemic complications can influence in a favorable way the number of these acute episodes in diabetics type I treated by an intensified insulin regime. Using a questionnaire method, the authors examined 40 diabetics type I without chronic complications, treated by an intensified insulin regime. The authors investigated the most frequent cause, clinical severity and number of hypoglycaemic episodes three months before and three months after a 10-day educational camp. During the three months before reconditioning in the group as a whole total of 600 hypoglycaemic episodes were recorded, while during the same period after reconditioning only 240. The most frequent causes before and after reconditioning were a physical load and a delayed meal. Education reduces markedly the severity and total number of hypoglycaemic episodes in diabetics type I.
