Comorbidity in the practice of a pulmonologist: gastroesophageal reflux disease, Zenker's diverticulum and bronchopulmonary pathology (a clinical case)

A clinical observation of a comorbid state in a 72-year-old patient with chronic bronchopulmonary pathology is presented in the work. Gastroesophageal reflux disease and large Zenker's diverticulum have been revealed. Diseases manifested simultaneously, progressed in parallel, but were not regarded as comorbid, which did not allow optimizing their therapy and prognosis.
