obstructive lung disease is when there is a problem with
getting air out of the lungs
The airflow in and out of the lungs. It occurs when the air passages become narrowed, inflamed and restricted, making it difficult for air to move freely through the airways.
The two most common types of obstructive lung disease are chronic obstructive pulmonary disease (COPD) and asthma. COPD is a group of lung diseases that include chronic bronchitis and emphysema, while asthma is a chronic inflammatory disorder of the airways.
In COPD, the airways become damaged and inflamed, resulting in a permanent narrowing of the air passages. This makes it difficult to breathe and can lead to symptoms such as coughing, wheezing, shortness of breath and chest tightness. COPD is most commonly caused by smoking, but can also be caused by exposure to air pollution or occupational hazards.
Asthma, on the other hand, is characterized by intermittent episodes of wheezing, coughing, chest tightness and shortness of breath. It is caused by airway inflammation and constriction of the smooth muscle in the airways. Asthma can be triggered by a variety of factors such as allergens, exercise, cold air, stress and respiratory infections.
Both COPD and asthma are chronic conditions that require ongoing management and treatment. Treatment options may include medications such as bronchodilators and inhaled corticosteroids, as well as lifestyle changes such as quitting smoking and avoiding triggers. Pulmonary rehabilitation and oxygen therapy may also be recommended in more severe cases.
