Abstract
Introduction: Adhesive capsulitis, commonly known as frozen shoulder, is a prevalent and painful condition that limits shoulder mobility. A strong association exists between diabetes and this condition. This study aims to investigate the inflammatory risk factors involved in the development of adhesive capsulitis in diabetic patients.
Materials & Methods: In a descriptive-analytical study, individuals diagnosed with adhesive capsulitis were evaluated over three years. Among these patients, those with a confirmed diagnosis of diabetes who were undergoing treatment were identified and included in the study. They were compared to non-diabetic individuals. A pre-defined questionnaire was used to collect demographic data, diabetes duration, treatment type, and laboratory findings, which were then analyzed for associations with this condition.
Results & Discussion: A total of 53 patients were examined, with the prevalence of concurrent diabetes and adhesive capsulitis being 47%. Hyperlipidemia and hypercholesterolemia showed a significant association with the co-occurrence of diabetes and adhesive capsulitis. The mean duration of diabetes was 4.43 ± 2.22 years in patients receiving oral medication and 4.55 ± 2.60 years in those on insulin therapy (P = 0.26). The mean HbA1C level was 7.72 ± 1.01 in the oral medication group and 6.71 ± 0.48 in the insulin therapy group, indicating a significant association between treatment type, diabetes duration, and the development of adhesive capsulitis.
Conclusion: Based on the findings of this study, the coexistence of hyperlipidemia and hypercholesterolemia with diabetes plays a significant role in the development of adhesive capsulitis.
