Measures that can be taken to control the alveoli from further enlarging include quitting smoking, improving the surrounding environment, avoiding infections, and aggressively treating the primary lung disease. 1. Smoking cessation: Smoking is one of the most important causes of emphysema and chronic obstructive pulmonary disease (COPD), which can promote the destruction of alveolar septa and accelerate the development of pulmonary alveoli. Therefore, people with a history of smoking should quit smoking or reduce smoking as much as possible to minimize the damage to lung tissue and effectively control pulmonary alveoli. 2. Improve the surrounding environment: environmental pollution is also one of the factors causing lung tissue damage, so people with alveoli should improve the surrounding environment as much as possible to reduce the damage of lung tissue caused by pollution, for example, pay attention to the protection of dusty work environment, away from chemical plants and other polluted areas, wear a mask to reduce the inhalation of fumes when cooking, and so on. 3. Avoid infection: long-term or repeated lung infections can easily cause alveolar septal rupture to form pulmonary blisters, so patients with pulmonary alveoli should pay attention to warmth in daily life to avoid infection, and should be treated as soon as possible when there is fever and cough and other signs of infection. 4. Actively treat the primary lung disease: many patients’ alveoli are secondary to certain lung diseases, such as chronic bronchitis, chronic obstructive pulmonary disease, tuberculosis, etc. Therefore, actively treating the primary disease is crucial to controlling the progress of alveoli. It is recommended that patients with pulmonary alveoli go to the hospital as soon as possible, and ask professional doctors to evaluate their condition and formulate a scientific treatment plan.
