THE PREVALENCE AND PATTERNS OF IMPAIRED LUNG FUNCTION IN IRAQI PATIENTS WITH TYPE II DIABETES MELLITUS

Background: Diabetes mellitus (DM) refers to a group of metabolic disorders that share the phenotype of chronic hyperglycemia, leading to chronic macrovascular and microvascular complications if not managed properly. Among these complications, lung involvement has been poorly characterized and followed worldwide, although the lung is a major organ in the body, same as other organs that are affected by microvascular and macrovascular complications. Aim of study: To determine the prevalence and patterns of impaired lung function in Iraqi patients with type II DM. Patients and methods: This cross-sectional study included (100) patients with II diabetes who were visiting Baghdad teaching hospital during the period from August 2014 to March 2015 for follow up. The patients accepted to take part in this study, after fulfilling the exclusion and inclusion criteria. The pulmonary function test was carried out using the Spirometer according to standard guidelines. Results: The results showed that 58 (58%) of type II DM patients had impaired pulmonary function, 38 (38%) had restrictive defect. Other impaired pulmonary functions showed that obstructive pattern constituted (13%) and mixed pattern constituted (7%) of the patients. Conclusions: Type II Diabetes mellitus can adversely affect and impair pulmonary function, this impairment, predominantly show restrictive pattern of airway disease, in addition to other less common patterns of involvement.
