Some children with juvenile idiopathic arthritis (JIA) may look different because they have growth problems. Depending on the severity of the disease and the joints involved, growth in affected joints may be too fast or too slow, causing one leg or arm to be longer than the other. Overall growth may also be slowed. JIA also may cause joints to grow unevenly or to one side. Doctors are exploring the use of growth hormones to treat these problems.

Children with JIA may also look different because of medication. Corticosteroids, a type of medication sometimes used to treat JIA, can result in weight gain and a round face. When the doctor stops giving the medication, these side effects may disappear.
