Lung Hyperinflation: A Complication of Breathing Disorders

3. Symptoms of Lung Hyperinflation

Hyperinflation of the lungs results in uncomfortable and frightening symptoms, including shortness of breath, tightness in the chest, and heavy, rapid, or shallow breathing. People with hyperinflated lungs describe an acute yet unsatisfied need to inhale and exhale, often referred to as "air hunger." Physical symptoms of hyperinflation may lead to emotional or psychological fear, anxiety, or panic. Respiratory distress can result, which intensifies the physical symptoms. Observable signs of chronic hyperinflation include changes in the walls of the chest, the shape of the diaphragm, and the muscle fibers in the lungs.
