Are you a clinician? See the clinical version of this page.

The short versionAdults who had juvenile idiopathic arthritis usually have good pregnancies, and joint disease is often low and steady, easing a little in pregnancy. It can pick up in the first weeks after birth, so the early weeks are worth watching. Fertility is normal. The main planning points are keeping disease controlled on pregnancy-compatible medicines and, for some people, thinking ahead about joints affected by earlier disease, such as hips or the jaw, which can matter for delivery and anaesthesia.

What to know

Will pregnancy affect my JIA?

Joint disease is usually low and steady, and often eases a little during pregnancy. It can pick up in the first weeks after birth, most often around 6 weeks, then settles again by about a year. Because that early flare is common, the first weeks after birth are a good time for a check-in. In this study women reported good mental health, and it was a little better in the weeks after birth.

Pregnancy outcomes and fertility

Most people do well and fertility is usually normal. Disease control before pregnancy gives the smoothest course.

Medicines

The medicines are the same as for adult inflammatory arthritis: hydroxychloroquine, sulfasalazine, azathioprine, and TNF inhibitors can usually be used; methotrexate is stopped before trying.

Joints, delivery, and anaesthesia

If earlier arthritis affected your hips, pelvis, jaw, or neck, your team plans ahead for delivery and pain relief, since these can affect positioning and anaesthesia.

Eye history

If your JIA involved eye inflammation, mention it, as your eye care continues alongside pregnancy care.
