A Cross Sectional Study on Impact of Diabetes Mellitus on Lung function Parameters

Abstract

Chronic hyperglycemia in Type 2 Diabetes Mellitus (T2 DM) is associated with ongoing damage, dysfunction, and failure of many organs, particularly the eyes, kidneys, nerves, heart, lungs, blood vessels and the diabetic patients may have considerable reductions in lung functioning. Diabetes Mellitus, Peak Expiratory Flow, and Fasting Blood Sugar are some of the terms used in this study. One hundred T2 DM patients, ranging in age from 30-70 years old and of either gender, were submitted to spirometry, vital parameters were recorded, glycated hemoglobin (HbA1c) and fasting blood sugar (FBS) were evaluated, and healthy controls were a matched. Diabetics forced vital capacity (FVC) ranged from 1.51 to 4 (Liters) with a mean of 2.4 ±0.6SD, whereas controls' FVC ranged from 2.2 to 4.74 with a mean of 3.14 ±0.7SD and a significant P value. (P<0.001) diabetics peak expiratory flow rate (PEFR) ranged from 188 to 459 (liters per minute) with a mean of 288 ±70SD, whereas controls PEFR ranged from 243 to 571 with a mean of 373±74 and a significant P-value. When compared to male diabetics, the PEFR in female diabetics was 239 ±38SD with a significant P-value. Spirometric parameters in male diabetics were found to be insignificant when compared to healthy controls (P <0.001). In both sexes, HbA1c and FBS were shown to be extremely significant when compared to controls. Variable PEFR in healthy controls and in the lung function was found to be impaired in female diabetics, but male diabetics had a normal PEFR.
