Type 2 diabetes mellitus impairs lung function, reducing forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). The severity of lung impairment correlates with the duration of diabetes.

Area of Science:

  • Pulmonary Medicine
  • Endocrinology
  • Diabetic Complications

Background:

  • Type 2 diabetes mellitus (T2DM) is a metabolic disorder with potential systemic complications.
  • Emerging evidence suggests T2DM may affect respiratory health, but the extent and relationship with disease duration require further investigation.

Purpose of the Study:

  • To investigate the impact of T2DM on pulmonary function.
  • To assess the correlation between the duration of T2DM and the severity of lung function impairment.

Main Methods:

  • A comparative study involving 32 male T2DM patients and 40 age, height, weight, and socioeconomic status-matched healthy male controls.
  • Spirometry was performed using an Electronic Spirometer (Schiller AT-2 Plus).
  • Statistical analysis included the 2-tailed Student's t-test.

Main Results:

  • T2DM patients exhibited significantly reduced forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF) compared to controls.
  • No significant differences were observed in the forced expiratory ratio (FEV1/FVC%) or FEF 25-75% between the groups.
  • A dose-response relationship was identified between diabetes duration and the degree of lung function impairment.

Conclusions:

  • T2DM is associated with impaired lung function, characterized by decreased FVC, FEV1, and PEF.
  • The duration of T2DM significantly influences the severity of lung function abnormalities.
  • These findings highlight the importance of monitoring respiratory health in patients with T2DM.
