Even if you have rheumatoid arthritis at the age of 28, if you receive systematic and standardized treatment to control the disease and reduce complications, it does not usually have an impact on your life expectancy. Rheumatoid arthritis mainly causes joint ankylosis and deformity, which can lead to loss of labor force, but generally does not directly affect life expectancy. Even if the patient has the disease early, as long as he or she goes to the rheumatology department of a regular hospital as soon as possible and follows the medical advice for systematic and standardized anti-rheumatic treatment, he or she can better control the development of the disease and reduce joint destruction and damage to the heart and lungs and other important organs. Patients’ life expectancy is generally not affected and they can live and work normally as ordinary people. However, if patients do not receive systematic and standardized treatment, as the disease progresses, not only joint damage will occur, but also interstitial lung fibrosis, decreased lung function, and cardiovascular adverse events, which can affect life expectancy in severe cases. Therefore, regardless of the age at which rheumatoid arthritis is diagnosed, patients should receive systematic and standardized treatment as early as possible to adequately control disease progression, reduce the occurrence of complications, and improve quality of life.
