Obesity is the one factor which affects cardiac as well as pulmonary function. So our study is to explore Cardiac and Pulmonary parameters among normal weight, overweight and obese subjects. Total 152 subjects were selected randomly for study between age group 15 to 45 years. They were divided into three groups on the basis of their Body Mass Index (BMI). Group A, BMI-18.6 to 24.9Kg/m² (normal weight), Group B, BMI-25 to 29.9Kg/m² (overweight) and group C, BMI >30Kg/m² (obese). After recording of anthropometric measurements all the subjects underwent measurement of the resting heart rate, blood pressure and following spirometric values, Forced vital capacity (FVC) in liters, Forced expiratory volume in first second (FEV1) in liters, Peak expiratory flow rate (PEFR) in liters/sec, Forced expiratory flow during the middle half of the FVC (FEF25–75%)liters/sec, FEF25% (Vmax25%)liters/sec, FEF50%(Vmax50%)liters/sec, FEF75%(Vmax75%)liters/sec and FEV1/FVC%. Our results show significant increase in Resting Heart Rate (RHR), Resting Blood Pressure (RBP) with increase in BMI. Spiromertic values FEV1/FVC% ratio and FEF75% were significantly changed with change in BMI, but not any significant difference was found in Pulse Pressure, Mean Arterial Pressure and FVC, FEV1, PEFR, FEF25-75%, FEF25%, FEF50%, FEF75%, in different BMI groups. A significant increase in RHR, SBP and DBP with increase in BMI could point towards an altered autonomic balance with increase in body weight. Obesity does not have effect on the spirometry parameters among healthy nonsmokers, except FEV1/FVC% and FEF75%. We recommend searching for alternative diagnosis in case of findings abnormal spirometry tests results in obese.
