Having lung blisters at age 30 does not usually affect life expectancy. Smaller lung blisters can be asymptomatic and only detected by examination and usually require no treatment; for larger lung blisters, they can cause pneumothorax, hemopneumothorax, or secondary infections, and in severe cases, can be life-threatening, and surgery is usually recommended. The severity of pulmonary blisters depends on the number, size and location of the blisters. 1. Smaller lung blisters are usually found incidentally during chest radiographs or chest CT examinations and often have no symptoms, require no special treatment and have no significant impact on life expectancy. 2. Larger lung pustules or multiple lung pustules can cause chest tightness, shortness of breath, hemoptysis and chest pain in a few patients, and the main complications are spontaneous pneumothorax, spontaneous hemopneumothorax, which can be life-threatening when bleeding is large and requires emergency surgery. For patients with pulmonary blisters, professional physicians should decide the follow-up treatment after combining the imaging examination and clinical manifestations. It is recommended that patients seek medical treatment in a timely manner in order to avoid delaying the condition and causing adverse consequences.
