The aim of the present study is to investigate the role of Helicobacter pylori in olfactory function. Thirty-six patients (mean age 38.5) aged between 18 and 55 years who were diagnosed with H. pylori by gastric biopsies and age- and sex-matched 30 healthy adults (mean age 33.6) were included in the study. All participants underwent a detailed ear–nose–throat examination including endoscopic examination of the nasal cavity and laryngeal area, and olfactory tests were performed using the Sniffin’ Sticks, a 12-item screening test (Sniffin’Sticks; Burghart, Wedel, Germany) and odor scores were recorded. The mean odor score was 7.9 ± 1.7 (range 2–10) in the patient group and 10.3 ± 1.4 (range 6–12) in the control group. There were significant lower scores in the patient group compared to the control group (p < 0.05). In conclusion, it is apparent that there is an association of H. pylori infection with olfactory dysfunction. H. pylori infection should be considered as possible etiological factors in patients with olfactory dysfunction.
