Background: Nasal obstruction and complaints are common attendance causes in otorhinolaryngology clinics. Obese patients are especially more vulnerable for these complaints. There is not enough data about nasal resistance and weight.
Patients and methods: One hundred ten patients who had no nasal complaint and nasal pathology were investigated by peak nasal inspiratory flow meter, nasal symptom evaluation scale (NOSE), and visual analog scale (VAS) calculation.
Results: According to the statistical analyses among the BMI groups, there is no significant difference detected. Peak nasal inspiratory flow values highly correlated with height. Height correlated with VAS and weight correlated with NOSE scores. VAS score highly correlated with NOSE score. Also, there is a negative statistically significant correlation between BMI and nasal congestion index.
Conclusion: All these data show that there is no relation between BMI and nasal resistance, and although the nasal congestion cycle is preserved in all BMI groups, nasal congestion index is decreased when the weight is raised.
