title: Bronchial hypersecretion, chronic airflow limitation, and peptic ulcer.
abstract: Men with and men without a history of peptic ulcers were compared using respiratory symptoms and spirographic measurements taken from data recorded in an epidemiologic study. Among the 1,049 men examined, 7% reported a history of peptic ulcer. A clear relationship appeared between bronchial hypersecretion and peptic ulcers. It persisted after adjustment for age, smoking habits, social class, and country of origin. Men with ulcers inhaled tobacco smoke more often. Ulcers, smoking, and chronic phlegm were independently related to a lower body build index. It seems that the relationship between smoking and ulcers was greater among men with chronic phlegm, and it is postulated that peptic ulcers and "chronic bronchitis" might be related to a "common secretory disorder." After adjustment for age, men with a history of peptic ulcers had, not a lower FEV1, but a higher vital capacity. A slightly lower FEV1/VC ratio cannot in such cases be considered as an index of chronic airflow limitation.
