Rheumatology question, why am i losing weight and eating full daily meals. just diagnosed with ra. on prednisone. starting methotrexate. can ra cause unintentional weight loss. i've lost twelve pounds last six months and am already too thin?

Rheumatoid arthritis leads to chronic inflammation and this can lead to weight changes, including weight loss. The prednisone tends to lead to weight gain as a side effect so this may help. You could also see a nutritionist to be sure you are eating the right diet to keep inflammation down while taking in enough calories to allow for weight gain. Best of luck to you!
