The aim of this descriptive research was to study the relationship between Quality of Life - QOL - and the eve of Hemoglobin A1c - HbA1c. Using purposive sampling, the sample size was 343 patients withType 2 Diabetes Mellitus--T2DM who were receiving medical services in DM--Diabters Mellitus clinic at the out-patient department at Amphorae Hospital. Data were collected by using the following questionnaires: Socio-demographic data, Health profiles and, The Diabetes Quality of Life Questionnaire, which had a reliability of the Alpha Cronbach’s coefficient of .85. Data were analyzed using descriptive statistics and Pearson Correlation Coefficients. The results showed that the overall score of QOL was high (M=5.01, SD.=1.34). Relationship between QOL of T2DM patients and HbA1c levels revealed a negative correlation and significant level (r= .156, p=.004). In conclusion, the study led to understandings about poorer glycemic control related to health problems and comorbidity and low quality of life for patients with T2DM.
