I have RD and was diagnosed in July. I have lost over sixty pounds in the last year, despite drugs like Prednisone, Hydroxychloriquine, MTX, Humira etc...I now weigh 103pds and I am 5'3". Body Mass Index is 18.5. So officially underweight. My concern is one bad infection and I have no reserves. Is anyone having difficulty with weight loss? I have lost another fifteen pounds since this photo. My husband is always so alarmed when he sees me undressed.
