Why copd person take a long time to breathe out?

Individuals with Chronic Obstructive Pulmonary Disease (COPD) often experience prolonged exhalation due to airway obstruction and reduced lung elasticity. The inflammation and damage to the airways make it difficult for air to flow out of the lungs, leading to a prolonged expiration phase. This inefficiency in expelling air can result in a buildup of carbon dioxide and a feeling of breathlessness. Additionally, the effort required to exhale can lead to fatigue, further complicating their breathing patterns.
