The researchers found that heavy obesity is associated with faster disability progression.
The study, published in the journal Arthritis Care and Research, also found that patients who lost weight tended to be disabled more quickly.

"This study suggests that patients with rheumatoid arthritis and obesity benefit from intentional weight loss through a comprehensive management strategy, however, if we see someone losing weight without trying it, it is likely to be a bad prognostic sign especially if they are already thin "
