Patients and Methods: A prospective study was conducted on 150 patients suffering from obstructive lung disease diagnosed by consultant pulmonologist on the basis of clinical and spirometry parameters. Body mass index was calculated in all the patients by WHO formula and they were classed as normal, overweight or obese depending upon body mass index. Factors like age, gender, tobacco smoking and ethnicity were associated with presence of obesity among the study participants.

Results: Out of 150 patients of obstructive lung diseases,85 (56.7%)were male and 65 (43.3%) were female. Mean duration of illness in our target population was 4.63±7.831 years. Out of total study participants, 47 (31.4%) had obesity while 103 (68.6%) did not show obesity and had body mass index less than 30 kg/m². Chi-square analysis revealed that tobacco smoking had statistically significant relationship with presence of obesity among the target population (p-value-0.001).

Conclusion: Around 1/3^rd of patients suffering from obstructive lung diseases had comorbid obesity as well. Patients who were tobacco smokers were more at risk of having obesity as compared to those who did not smoke tobacco.
