Journal Title: Journal of the Indian Medical Association - Year 2018, Vol 116, Issue 4
Abstract
The present work is undertaken to study the effect of 2-5 years of tobacco chewing on pulmonary functions. The study group consisted of 30 male, young, healthy subjects, free from cardiopulmonary diseases and with history of tobacco chewing of 2-5 years duration, on an average of 5 packets of Gutkha per day. The control group consisted of 30 age and sex matched healthy individuals who had never chewed tobacco. The pulmonary function tests were carried out using electronic spirolyser. There was a significant lowering of the following parameters in tobacco chewers, forced vital capacity (FVC), forced expiratory volume at the end of first second (FEV1), maximum midexpiratory flow (MMEF), peak expiratory flow rate (PEFR). This study shows that 2-5 years of tobacco chewing leads to a definite tendency to narrowing of large airway.
