What is the cause of left lung bronchiectasis

Fibrosis causes the muscles and elastic tissues on the bronchial walls to be destroyed. The consequence of this situation is that the bronchi gradually deform and after a long time they become dilated. Some typical symptoms of bronchiectasis are coughing, coughing up thick sputum, and even coughing up blood. So what should we do if we have bronchiectasis in the left lung? What is the cause? Let's take a look.

1. Infection. Infection is the most common cause of bronchiectasis. Pulmonary tuberculosis, whooping cough, and adenovirus pneumonia may cause bronchiectasis. Aspergillus and mycoplasma, pathogens that can cause chronic necrotizing bronchopneumonia, can also cause bronchiectasis.

2. Congenital and hereditary diseases. The most common hereditary disease causing bronchiectasis is cystic fibrosis. In addition, Marfan syndrome may also cause bronchiectasis, probably due to poor development of connective tissue.

3. Abnormal cilia. Abnormal cilia structure and function are important causes of bronchiectasis. Kartagener syndrome presents with a triad of situs inversus, sinusitis, and bronchiectasis. This disease is accompanied by abnormal ciliary function.

4. Immunodeficiency. Deficiency of one or more immunoglobulins can cause bronchiectasis. Deficiency of one or more IgG subclasses is usually accompanied by recurrent respiratory tract infections, which can cause bronchiectasis. IgA deficiency is not often associated with bronchiectasis, but it can coexist with IgG2 subclass deficiency, causing recurrent suppurative lung infections and bronchiectasis.

5. Foreign body inhalation. The long-term presence of foreign bodies in the airway can lead to chronic obstruction and inflammation, and secondary bronchiectasis.

Steps/Methods:

1 Patients with bronchiectasis and infection in the left lower lobe should undergo a detailed and targeted examination of their lung infection and bronchiectasis during treatment. If the disease is found to be more serious, surgical treatment is required. If the disease is mild, drug treatment is sufficient.

2 The genetic factors of patients with left lower lobe bronchiectasis and infection may be related to the onset of their own bronchial diseases. Patients with severe deficiency of α1-antitrypsin metabolism in their bodies may develop emphysema and other diseases or other complications.

3. In patients with bronchiectasis and infection in the left lower lobe of the lung, the metabolic epithelial cells of the bronchial mucosa undergo degeneration, necrosis, or even other shedding, which will cause the cilia of the ulcer cells to become shorter or uneven, and the cell metabolic system in the body will enter a period of retention remission, which will affect the mucosa.

The above mentioned the causes and treatment methods of left lung bronchiectasis. The following are some precautions. First of all, patients with left lobe bronchiectasis generally have thinner epithelial cells and hyperplasia, which may worsen the patient's condition. Another important thing is that you must not smoke. Smoking has a great impact on respiratory diseases. It is best to combine it with Chinese medicine during treatment.
