Wheezing

Wheezing is a high-pitched whistling sound that occurs during breathing, typically when exhaling. It is a common symptom of various respiratory conditions.

Causes of Wheezing

• Asthma: A chronic inflammatory disease characterized by recurring episodes of wheezing, coughing, and shortness of breath.
• Chronic Obstructive Pulmonary Disease (COPD): A progressive lung disease that includes conditions such as emphysema and chronic bronchitis, often causing wheezing.
• Pneumonia: An infection of the lungs that can cause wheezing, coughing, and difficulty breathing.
• Bronchiolitis: A common respiratory illness in young children, characterized by wheezing, coughing, and difficulty breathing.
• Allergies: Allergic reactions to substances such as pollen, dust mites, or pet dander can trigger wheezing.

Characteristics of Wheezing

Wheezing can be described as:

• High-pitched and whistling
• Loud or soft
• Constant or intermittent
• Worse during exercise, cold air, or at night

Diagnosis of Wheezing

To diagnose the underlying cause of wheezing, a healthcare professional may:

• Perform a physical examination
• Take a medical history
• Conduct lung function tests, such as spirometry or peak flow measurement
• Order imaging tests, such as chest X-rays or computed tomography (CT) scans
• Perform allergy testing or blood tests to rule out underlying conditions

Treatment of Wheezing

Treatment for wheezing depends on the underlying cause and may include:

• Medications, such as bronchodilators, corticosteroids, or antibiotics
• Oxygen therapy to help increase oxygen levels in the blood
• Pulmonary rehabilitation programs to improve lung function and overall health
• Avoiding triggers, such as allergens or irritants, that can exacerbate wheezing
