Post-COVID lung disorder, also known as post-acute sequelae of SARS-CoV-2 infection (PASC) or long COVID, refers to a range of persistent respiratory symptoms and complications that occur after recovering from COVID-19. While many individuals with COVID-19 experience mild to moderate symptoms that resolve within a few weeks, some continue to experience respiratory issues and other symptoms for an extended period. Common post-COVID lung disorders include:

Persistent Shortness of Breath: Some individuals experience ongoing shortness of breath, even after recovering from the acute phase of COVID-19. This can be due to lung inflammation, scarring (pulmonary fibrosis), or reduced lung function.

Chronic Cough: A persistent cough may develop post-COVID, possibly due to airway inflammation or irritation.

Fatigue: Fatigue is a common symptom of long COVID and can be exacerbated by respiratory issues and decreased lung function.

Exercise Intolerance: Individuals with post-COVID lung disorders may experience difficulty exercising or engaging in physical activity due to shortness of breath and reduced lung capacity.

Chest Pain or Tightness: Some individuals may experience ongoing chest discomfort, pain, or tightness, possibly due to inflammation or scarring of lung tissue.

Reduced Lung Function: COVID-19 can cause damage to the lungs, leading to reduced lung function and impaired oxygen exchange, which may persist after recovery.

Management of post-COVID lung disorder focuses on alleviating symptoms and improving respiratory function. Treatment may include:
