Quality of life is a multi-dimensional concept influenced by many objective environmental factors and personal factors based on which are evaluated certain aspects of life. In this process of evaluating the quality and satisfaction with life in general and satisfaction in some areas, the important role have our personal beliefs and attitudes and the importance we attach to events in our life. According to this, the assessment of the quality of life associated with health relates to the mutual relationship, the impact of the health condition and general functioning. It has been proven that diseases by their characteristics and physical and functional constraints, among which definitely stand out chronic diseases with long-term treatment and rehabilitation, affect the quality of life. Part of this group of chronic diseases is diabetes as well, for which many authors believe it represents the most endocrine disorder, and which is, according to epidemiological data, ranked among the most common diseases associated with increased comorbidity and mortality of the population. Diabetes itself imposes certain limitations on the patient's life and requires a protocol in the treatment of the fundamental disease and its complications. The aim of this research was to examine some aspects of the quality of life of persons with type 2 diabetes and to examine the perception of the effect of diabetes on quality of life. Methods and respondents For the purpose of the research was created an appropriate survey questionnaire which was applied to a suitable sample of 62 subjects with diabetes mellitus. The questionnaire collects data on the socio-demographic characteristics of the respondents, examines the characteristics of the disease and assesses aspects of quality of life. The study was carried out in the Nedelišće Diabetes Association and within the Health Center of Čakovec in the Belica Municipality. Collected data were processed in the trial version of the IBM SPSS Statistics software and there were used standard statistical tests. The results obtained in the paper are presented in tables and graphs. To conclude, this research confirms existing research on the reduction of the quality of life and the diversity of the subjective experience of satisfaction with certain aspects of the life of people suffering from diabetes.
