Severe Persistent Asthma
What is Severe Persistent Asthma?
Severe persistent asthma is a type of asthma where symptoms occur frequently and are difficult to control despite the use of prescribed medications. It is characterized by chronic inflammation of the airways, leading to frequent flare-ups, wheezing, shortness of breath, and coughing. This form of asthma can significantly impact daily activities and quality of life.
Causes of Severe Persistent Asthma:
- Allergens: Exposure to pollen, dust mites, pet dander, or mold
- Respiratory infections: Viral infections, particularly in early childhood
- Genetic factors: Family history of asthma or other allergic conditions
- Air pollution: Exposure to smoke, pollution, or strong odors
- Physical activity: Exercise-induced asthma, especially in cold or dry air
- Occupational factors: Certain workplace irritants or allergens (e.g., chemicals or dust)
Common Signs and Symptoms:
- Frequent coughing, especially at night or early morning
- Shortness of breath
- Wheezing or whistling sound when exhaling
- Tightness in the chest
- Difficulty sleeping due to asthma symptoms
- Increased use of rescue inhalers
Popular Treatment Methods:
- Inhaled corticosteroids: To reduce airway inflammation
- Long-acting beta-agonists (LABAs): To help keep airways open
- Biologic therapies: For severe cases, medications like monoclonal antibodies may be used
- Rescue inhalers: Fast-acting bronchodilators to relieve acute symptoms
- Allergen avoidance and environmental control: Identifying and avoiding triggers such as pollen, dust, or smoke
Severe persistent asthma requires ongoing management to prevent symptoms from worsening and reduce flare-ups. Proper treatment and lifestyle adjustments can help individuals maintain a higher quality of life.
