The incidence and prevalence of Type 2 Diabetes Mellitus (DM) are increasing worldwide. Due to the restrictions, increased stress, and increased sedentary life during the pandemic, deterioration in diabetes control is expected. The aim of this study is to determine the effect of COVID-19 on HbA1c values and how it affects diabetes control. In our study, a total of 6217 diabetic patients were examined retrospectively in 5 separate periods (March 2018-February 2019, March 2019-February 2020, March 2020-February 2021, March 2021-February 2022, March 2022-February 2023). According to the HbA1c value; those with HbA1c values were classified as well-controlled, those between 7-9% as poorly controlled, and those >9% as very poorly controlled. In addition, LDL, HDL, cholesterol and fasting blood sugar values were recorded. There are significant differences between the groups in terms of HbA1c measurements (p<0.001). The lowest HbA1c value was found to be 7.61% in the measurement between March 2018 and February 2019, and the highest value was found to be 8.39% in the measurement between March 2020 and February 2021. The HbA1c very poor control rate was the highest in March 2020 and February 2021 (30.9%), and the good control rate was the highest in March 2018 and February 2019 (51.3%). In our study, HbA1c values and poorly controlled patient rates were found to be higher during the pandemic period. Considering this result, it can be said that the pandemic process caused deterioration in disease control in Type 2 diabetes patients.
