Chronic Cough and Esophageal Diverticulum: Clinical Connection

Pathophysiological Connection

Esophageal diverticula can cause chronic cough through direct irritation of the esophageal-bronchial reflex pathway 1
Associated gastroesophageal reflux disease (GERD) commonly coexists with diverticula, contributing to chronic cough 1, 2
Worsening of cough when lying down is a positional effect allowing regurgitation, consistent with esophageal diverticulum 2
Complete resolution of cough during travel may suggest dietary changes or different eating patterns influence the condition 2, 3

The American College of Radiology confirms esophageal diverticulum and acid reflux as strong evidence for the etiology of chronic cough 4
Cough exacerbated by meals and positional worsening (nighttime) are characteristic of reflux-related cough 2
Up to 75% of patients with reflux-related cough may not have typical GI symptoms like heartburn, making the connection less obvious 1

Intensive antireflux therapy, including antireflux diet and proton pump inhibitor therapy, is recommended for chronic cough associated with esophageal diverticulum and GERD 2, 3
Prokinetic therapy may be considered if initial treatment is insufficient 5
Positional therapy, such as elevating the head of bed and avoiding meals within 3 hours of bedtime, can help alleviate symptoms 2

Resolution of cough during travel can be a critical diagnostic clue suggesting environmental or dietary factors influence the condition 3
Social embarrassment from chronic cough significantly impacts quality of life and should be considered when determining treatment intensity 5
