What causes pulmonary bullae?

In general, pulmonary bullae refer to large air spaces in the lungs. Pulmonary bullae may be caused by congenital factors, pneumonia, emphysema, bronchiectasis, asthma, and other conditions. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Congenital factors

This may be related to abnormal embryonic development, such as incomplete alveolar development, leading to the formation of pulmonary bullae and symptoms like chest tightness and shortness of breath. Medications such as Compound Liquorice Tablets, Ren Shen Bao Fei Pills, or Tong Xuan Li Fei Pills may be used under medical guidance.

2. Pneumonia

Pulmonary bullae may result from bacterial or viral infections that increase intra-alveolar pressure, causing alveolar wall rupture. Symptoms often include fever, cough, and sputum production. Treatment may include antiviral or antibacterial medications such as Acyclovir Capsules, Cefalexin and Trimethoprim Tablets, or Ribavirin Tablets, under a doctor's supervision.

3. Emphysema

Usually caused by infection, emphysema can damage alveolar walls and lead to the development of pulmonary bullae, accompanied by symptoms such as dyspnea, cough, and sputum production. Medications such as Baiji Granules, Tankejing Tablets, or Qutan Zhi Ke Granules may be used under medical advice.

4. Bronchiectasis

Typically due to infection, this condition causes thinning and reduced elasticity of airway walls, which may rupture and coalesce into pulmonary bullae. Common symptoms include chronic cough, sputum production, and hemoptysis. Treatments may include Salbutamol Sulfate Tablets, Terbutaline Sulfate Nebulizer Solution, or Salmeterol Xinafoate Inhalation Aerosol, as directed by a physician.

5. Asthma

Often hereditary, asthma leads to airway narrowing and impaired air expulsion, potentially resulting in pulmonary bullae. Symptoms include recurrent episodes of wheezing, shortness of breath, chest tightness, or coughing. Medications such as Compound Aminophylline Tablets, Dyphylline Tablets, or Doxofylline Tablets may be used according to medical instructions.

In daily life, maintaining healthy eating habits is recommended—eating three balanced meals at regular times without overeating. Consuming nutrient-rich foods such as lean meat, fish, eggs, milk, and carrots can help improve overall nutrition and boost immunity.
