Four weeks exercise in obstructive sleep apnea syndrome patient with type 2 diabetes mellitus and without continuous positive airway pressure treatment: A case report

Abstract

The purpose of this study was to investigate the effect of exercise in patient with obstructive sleep apnea syndrome (OSAS) and type 2 diabetes mellitus (T2DM) and without continuous positive airway pressure therapy (CPAP) treatment, in polysomnography and cardiopulmonary exercise testing (CPET) parameters. 41 years old man with T2DM underwent full overnight polysomnography (PSG) and 48 hours after PSG performed maximal CPET. Patient re-checked after 24 and 28 weeks. After the 24 weeks follow-up the patient underwent 4 weeks aerobic exercise. The results showed changes between baseline and after 4 week exercise in parameters of polysomnography study, blood test and cardiopulmonary exercise testing. The findings of our study suggest that exercise can reduced the apnea-hypopnea index, improve the sleep quality and reduced the hemoglobin A1-c levels in patients with OSAS and without CPAP treatment.
