Diabetes mellitus is a disease that is defined as impaired glycemic control due to insulin resistance or impaired pancreatic insulin production. The prevalence is rising worldwide with Croatia not being an exception. It effects patient’s lipid metabolism which is one of the main causes of morbidity and mortality. The aim of this study was to investigate the state of metabolic control in patients being treated for T2DM in the CHC Rijeka. The data of 104 patients was used that were admitted for a counseling program of the daily hospital in the period from the 16th of March 2022 until the 29th of March 2023. Parameters included the age at the time of examination, age at the time of diagnosis, hemoglobin A1c, fasting plasma glucose, body mass index, total cholesterol, lowdensity lipoprotein, high-density lipoprotein, and triglycerides. The median age of participants at the time of examination was 62 years and the mean BMI was 30.19 kg/m2 . The mean value of HbA1c was 8.2% and the mean of LDL was 2.74 mmol/L, respectively. HbA1c values were higher in patients with a long-term diagnosis compared to those that have been recently diagnosed with T2DM. Target value of HbA1c < 7% was reached by only 26.9% of participants. LDL threshold values were reached by slightly more than a fifth of the participants (20.2%). Overall excellent metabolic control, considering LDL, HDL and TG values were only reached by 16.3 % of all participants. The study showed the metabolic control off the participants wasn’t satisfactory however, it was to be expected since they were all referred to the daily hospital to be educated on how to manage their disease. Reasons for referral were either evidence of long-term neglect of glycemic control or a recent diagnosis of T2DM.
