Exercise Intolerance in Occupational Lung Diseases: A Narrative Review of Pathophysiology and Clinical Assessment
By Ashriya Juriani.
Abstract
Introduction
Occupational lung diseases result from workplace exposure to dusts, fibres, fumes, gases, vapours, sensitising agents, and bioaerosols. These diseases can cause substantial exercise intolerance, affecting physical activity, work capacity, safety, and quality of life.
Objectives
To summarise the pathophysiological mechanisms of exercise intolerance in occupational lung diseases and describe a practical framework for its clinical assessment.
Methods
This narrative review synthesised evidence from PubMed/MEDLINE, Scopus, Google Scholar, relevant reviews, clinical guidelines, and professional society standards addressing occupational respiratory disease, exercise limitation, pulmonary function, gas exchange, exercise testing, muscle function, and functional capacity.
