How long a person with asthma lives depends on how well the disease is controlled and whether it is combined with other underlying diseases, so the survival time varies from patient to patient. Asthma is a metabolic disease and requires long-term treatment to control the disease. If patients with asthma can adhere to standard treatment, reduce the frequency of acute attacks, and have no other underlying diseases, they will mostly survive for a long time, and the length of survival is not significantly related to asthma. If the patient does not usually undergo standardized treatment, and also has a combination of serious heart and lung diseases, and the frequency of asthma attacks is high, the patient is prone to respiratory failure and may have a life-threatening condition at any time. In addition, patients with asthma, whether well-controlled or poorly-controlled, may have life-threatening conditions if they are not relieved promptly and effectively during an acute asthma attack. Patients with asthma are advised to avoid exposure to factors that trigger acute asthma attacks, such as dust, pollen, oil smoke, etc., and to quit smoking and drinking.
