Alcohol-induced upper airway symptoms: prevalence and co-morbidity

SummaryLittle is known about effects of alcohol intake on the upper, nasal airways. The present aim was to examine the prevalence of alcohol-induced nasal symptoms (ANS) and to explore associations between ANS and other respiratory diseases. A postal questionnaire focused on respiratory diseases and symptoms was sent to 11,933 randomly selected adult individuals. Subjects with ANS, n=316 (3.4%) received a second questionnaire focusing on this condition. Nine thousand three hundred and sixteen (78%) subjects answered the first and 228 (72%) the second questionnaire. Two-thirds of the subjects with ANS were women. Red wine and white wine were the most frequent triggers of ANS, reported by 83% and 31% of the subjects, respectively. Nasal blockage was the most prominent symptom, but also sneezing, nasal discharge, as well as lower airway symptoms occurred after intake of alcoholic drinks. Self-reported physician's diagnoses of asthma, chronic bronchitis⧸emphysema, chronic obstructive pulmonary disease (COPD), as well as allergic rhinitis were more common in subjects with ANS compared with the general population (P
