Obesity and rheumatoid arthritis (RA) have a complicated relationship. Although obesity raises the risk of RA and worsens its clinical course, higher body mass index (BMI) is associated with lower mortality. This is known as the “obesity paradox” in RA.

Scroll through the slides for an overview of the link between body weight and RA-and the clinical implications of the obesity paradox.
