This study becomes significant as it is being conducted in Sikkimese population who resides in high altitude have a different lifestyle. Objective To evaluate the risk factors for laryngopharyngeal reflux among Sikkimese origin. Method Patients of Sikkimese origin visiting Ear Nose Throat outpatient department Were administered with validated questionnaire. The patients were further subjected to validate Reflux symptom Index score. Indirect laryngoscopy was performed to calculate reflux finding score. Presence of laryngopharyngeal reflux was identified with patients having reflux symptom index and reflux finding score of greater or equal to 13 or more and 7 or more. Result Out of 200 subjects analysed, there were 77(38.5%) male and 123(61.5%) female. Heartburn and regurgitation were the most common symptom among the masses. Hoarseness and frequent throat clearance were the commonest laryngopharyngeal reflux symptoms. Various risk factors were computed as mentioned in the results column.
