For RA, patients can see results as soon as a few months
Though stem cells provide an exciting new avenue of rheumatoid arthritis treatment, everyone's response will be a little different. This is because everyone's body responds to things differently, and that includes stem cell therapy. There isn't any way to know how fast you will see any results, or how dramatic they will be either. However, most people report that they see results within a few months, though it might take as long as 9 months for a patient to notice any differences.
