How are pulmonary bullae formed?

The most common causes of bullae are COPD, emphysema, and bullae caused by COPD. They are often accompanied by chest tightness and breathing difficulties. They often need to be treated with some measures, such as inhaling long-acting bronchodilators. In addition, attention should be paid to smoking cessation and preventing respiratory infections. These non-drug treatment measures also help prevent the progression of the disease. Bullae may also be caused by congenital abnormalities. Most bullae caused by congenital abnormalities do not require special treatment, but it is important to note that bullae can sometimes be complicated by spontaneous pneumothorax. If bullae are complicated by spontaneous pneumothorax, surgical treatment may be considered.
