The life expectancy of a patient with pleurisy depends mainly on factors such as the cause of the pleurisy, the treatment and the patient’s physical condition. If the pleurisy is caused by infection, tuberculosis, etc., and the infection is well controlled with no significant sequelae, the patient’s life expectancy is usually not affected and is no different from that of a normal person. If the patient’s infection or tuberculosis is not controlled and turns into chronic pleurisy, or even serious infection complications occur, or even respiratory failure, etc., the patient’s life may be endangered. For pleurisy caused by rheumatism, if the primary disease is well controlled or if there is a legacy of pain during breathing, pain medications can be applied for symptomatic management, which generally has no significant impact on the survival of the patient. Therefore, pleurisy generally does not pose an impact on the life of the patient. However, if a septic chest forms and a fibrous plate is formed, it can eventually lead to thoracic collapse, which in turn can have an impact on the patient’s quality of life.
