Aim: The study aimed to identify the factors that complicate the management of diabetes of Type 2 Diabetes Mellitus patients to disease processes. Material and Method: This descriptive study was conducted with 150 Type 2 Diabetes Mellitus patients who consulted Van Regional Training and Research Hospital Internal Medicine Polyclinics for medical exam and control between April-August 2015 and who fit the research criteria. In the study, “Patient Information Form” was used to identify patients’ personal and medical characteristics and “Diabetes Care Profile” scala to determine the factors that complicated diabetes control. SPSS 23 statistics software program was used in data analysis. Results: Mean age for 150 participants was found to be 56.77±10.43 years, mean Fasting Blood Glucose was 214.04±87.74, HbA1c was 10.17±2.63 and Body Mass Index was found to be 29.53±5.05. Negative attitude mean score was identified to be the highest (3.09±1.14) factor among salient factors that complicated diabetes management whereas barriers in treatment had the lowest mean score (1.31±0.56) in diabetes management. It was determined that socio-demographic characteristics such as gender, age, education, status of employment and economic status and characteristics related to disease such as time of diagnosis, having regular check-ups, number of hospitalizations, type of treatment and existence of chronic complications related to diabetes have been found factors that complicate controlling diabetes (p<0.05). Conclusion: Metabolic control of patients with type 2 diabetes was not at a good level and their negative attitudes toward the disease were high. Some of the sociodemographic and diseaserelated characteristics of the patients made diabetes control difficult. It is proposed to further support the patients in diabetes management, to make appropriate attempts to change their negative attitudes, to plan the control problems faced by the patients and to identify the affected social and personal needs and to remove the barriers.
