OBJECTIVES: Two surveys were conducted to assess the impact of nocturnal and daytime hypoglycaemia on the individual and on the Turkish economy. METHODS: People with diabetes who had experienced a non-severe hypoglycaemic event in the 4 weeks prior to the survey were eligible for inclusion. The surveys were conducted face to face; all information, including hypoglycaemic events, was self-reported. RESULTS: In the Turkish cohort, 95 people responded (50 for the nocturnal survey [N]; 55 for the daytime survey [D]). Mean age was 49 years/48 years (N/D), mean weight was 76.9 kg/75.2 kg (N/D), 40%/31% (N/D) of respondents were male, and 64%/80% (N/D) had type 2 diabetes. Among respondents with type 2 diabetes, 63%/48% (N/D) received insulin ± OADs and 63%/66% (N/D) received OADs ± insulin. Non-severe hypoglycaemic episodes were experienced at least once/week by 20%/35% (N/D) and at least once/month by 58%/73% (N/D) of respondents. After the non-severe nocturnal (N)/daytime (D) hypoglycaemic event, 16% and 9% (N/D) of respondents decreased their insulin dose and 16% and 20%, respectively, contacted a healthcare professional. On average, respondents used 1.5 or 1.6 (N/D) extra blood glucose tests the following week, and 34%/26% (N/D) of those surveyed reported a high level of fear of a hypoglycaemic event. Of respondents who worked for pay (n=22/17), 59%/77% (N/D) reported a high/medium impact on work productivity following a hypoglycaemic event. Mean time to return to sleep following a nocturnal event was 60 minutes; 28% reported that the event had a high impact on sleep, and 54% had difficulty focusing at work the next day.  CONCLUSIONS:  In Turkey, nocturnal and daytime non-severe hypoglycaemic events impact quality of life, utilisation of healthcare resources and productivity in people with diabetes.
