Hi. Thanks for your query. Noted the history about your Mother and understood the concerns. Rheumatoid arthritis is basically a disease of joints and can affect the other ystems of the body. But it is important to know whether any other causes that have autoimmune base have caused the problems in the lungs and liver. Since she is on Deflazacort for so long Razo needs to be given to avoid the acidity related issues. Also needed is to go for the blood tests for: cortisone, CBC with ESR regularly; liver, thyroid, kidney functions; serum calcium and Vitamin D and to replenish as per the reports. Consult a Rheumatologist for further clinical evaluation, examination, investigations and proper management. Give her calcium containing diet. Multivitamins with mineral and Lycopene act as antioxidants well. Physiotherapy is an integral part of the management of Rheumatoid arthritis. Yoga, meditation and such things do help a lot in control of autoimmune disorders. Change in lifestyle can help and avoid stress and anxiety.
