This study aims to assess long-term complications, treatment patterns, and QoL of diabetic patients during COVID-19. Methods: A cross-sectional study was conducted on 385 diabetic patients (aged 18-80) from tertiary hospitals in Dhaka and Mymensingh between May and October 2022. Data were collected via a semi-structured questionnaire on sociodemographics, complications, treatment patterns, and QoL (SF-12 scale). Chi-square tests, ANOVA, and linear regression were used for inferential analysis. Results: The sample predominantly included middle-aged males (41 - 55 years) with type 2 diabetes. Diabetic retinopathy (34.5%), polyneuropathy (32.2%), and hypertension (52.3%) were the most common complications. Oral medications were used by 59.7% of patients, with 29.1% on insulin. Chi-square analysis showed a significant association between treatment adherence and complications (p < 0.05), with insulin users exhibiting more complications than those using oral medications. ANOVA revealed that insulin users had significantly lower QoL scores compared to oral medication users (p < 0.01). Linear regression analysis indicated that treatment adherence and age were significant predictors of QoL (β = 0.45, p < 0.01). Poor treatment adherence was associated with poorer QoL. Conclusion: Complications in diabetic patients significantly affect QoL in Bangladesh. Treatment adherence, especially with oral medications, positively impacts QoL. There is a need for improved access to diabetes care to manage complications and enhance the overall well-being of diabetic patients. %K Diabetes Mellitus %K Quality of Life %K Long-Term Complications %K Treatment Patterns %K Bangladesh %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=140617
