Goal: To determine main causes of the complication and the death in patients with diabetes, and to identify strategies for preventing from complication and deaths due to diabetes and improving quality of life and prolonging the life of diabetes patients.Objectives:1. To determine the occurrence of diabetes-related complications2. To study the causes diabetes-related complications and deaths3. To study prevention methods for these complicationsMaterials and Methods: From 17953 patient records from the past five years (2005-2009) of the State Clinical Hospital, we have selected 296 records from patients with diabetes. From these records we collected the following information: age, sex, duration of disease, type of work and complications experienced. Also from 2825 death cases, we have selected 48 patient records from the same period. We extracted information on age, sex, type of work and cause of death. Result: Compared to the 1997 data, kidney complications occurred in 68.9% of cases, which has risen from 25.6%. Eye complications occurred in 29.8% (1997) and have fallen to 19.6%. Leg complications rose to 12.8% which may indicate a continued rise in the future. It is evident from the study that type 2 diabetes occurs more often in people from urban areas (75.3%), who have sedentary jobs (87%), with poor health habits, and excess food and alcohol intake.Conclusion: The control of the primary and secondary health organization of the patients with diabetes are poor and preventative medication such as insulin are introduced late. There is poor public knowledge of healthy lifestyle and too much dependence on free drugs and no self-healthmanagement, patients seek medical treatment at late stages, and free drug distribution by order of the Minister of Health is not adequate.
