What is juvenile idiopathic arthritis?
Juvenile idiopathic arthritis (JIA) is inflammation (swelling) of one or more of your joints. It first occurs before your 16th birthday.
JIA is slightly more common in girls. It most commonly occurs in pre-school age children or teenagers.
There are different types of JIA and symptoms vary between the different types. Knowing which type you have helps assess the likelihood you''s often managed in a very similar way to JIA.
What should I look out for?
If you have any of these symptoms for more than a couple of weeks, you should see a doctor:
- painful, swollen or stiff joint(s)
- joint(s) that are warm to touch
- increased tiredness
- a fever that keeps returning
- a limp but no injury.
If you think that you or someone you know may have JIA, book a GP appointment as soon as possible. Tell them your symptoms and concerns. They''t completely understand what causes JIA. In fact, that''is-jia-genetic-''s very rare to have two people in the same family with JIA, but we do know that genetic factors are involved. This is to do with the genes that are passed down from your parents.
JIA is thought to be due to a combination of genetic factors and trigger factors from the environment, for example the infections that your immune system has been in touch with.
There’s no evidence that a specific infection causes JIA, but an infection may trigger your immune system''s often mild.
Most likely type to cause eye inflammation (chronic anterior uveitis) – you''s the painless type that doesn''ll affect you but usually the fever and rash will settle, although the arthritis may continue for several years before settling.
How will JIA affect me?
Many children who have JIA won''re adults, but it’s not possible to accurately predict this. In most cases, childhood arthritis has a good outcome. You should look forward to a future that’s no different from those of your friends and classmates.
In at least 30% of cases, however, arthritis can remain active into adult life. Some young adults with JIA have joint damage that limits their daily activities to some extent and a few may need joint replacements. Other problems can sometimes occur. Some people are physically smaller than average or have osteoporosis as a result of their arthritis and/or treatment with steroids.
A successful outcome in JIA requires many things, including:
- a positive approach
- an experienced team working alongside your GP
- a caring, helpful environment with support from family, friends and teachers.

Non-steroidal anti-inflammatory drugs (NSAIDs)
Non-steroidal anti-inflammatory drugs (NSAIDs) often help to reduce pain, stiffness and swelling.
Examples of the many NSAIDs include ibuprofen, piroxicam, naproxen and diclofenac. These have to be taken regularly to get maximum effect, which lasts hours not days.
Side-effects include indigestion and other stomach problems. The risk of this happening can be reduced by always taking them with food. You should tell your doctor or rheumatology nurse specialist if you develop any stomach pains or cramps.

Disease-modifying anti-rheumatic drugs (DMARDs)
Disease-modifying anti-rheumatic drugs (DMARDs) dampen down inflammation and can reduce the joint damage caused by arthritis.
Methotrexate is the most commonly used DMARD in JIA. It can be given as a weekly dose by mouth or injection.

Just like DMARDs, they slow down the progress of arthritis and reduce pain, swelling and stiffness.
arthritis and agehow to arthritis and age for Like DMARDs they work by suppressing the immune system, and they’re called biological therapies because they were developed from research into the biology of arthritis. These drugs are used if you don’t respond to DMARDs such as methotrexate.
A common treatment for young people is a steroid injection into the affected joint.
- Injections are very effective for many months, are very well tolerated and cause very few side-effects.
- In younger children these injections will be done under general anaesthetic, but as you get older these may be done under sedation, with gas and air (entonox) or awake with a local anaesthetic. In adult clinics, joint injections are always given with a local anaesthetic when you’re awake.
Steroid tablets are used less for young people than steroid injections.
- Side-effects are more common with large doses and longer courses (over weeks and months).
- Short courses (for a few days or up to a week) or low doses tend to have few or no side-effects. Your doctor will try and limit side-effects by putting you on a low dose or short course.
- Your doctor will give you a steroid card which tells people you’re on steroids. Always carry this with you.

The risk of chickenpox – Chickenpox can be more severe if you’re taking steroids, methotrexate or biological therapies.
If you haven’t had chickenpox (or aren’t sure) then tell your doctor or rheumatology nurse. They’ll give you advice on what to do if you get chickenpox or have been around someone with the condition. You may be able to have a vaccine.
If you need to have a vaccination, talk to your rheumatology team or GP. You might need to avoid some live vaccines if you are taking certain DMARDs or biological therapies. For more information about individual drugs, visit our drugs content and search by the name of the drug you are taking. There is a section on vaccinations for each drug.
Avoid drinking alcohol – Alcohol makes your liver more sensitive to the effect of methotrexate, which increases the risk of liver damage. You may be advised not to drink alcohol at all, but in truth many young people do drink some alcohol without apparent side-effects with their liver.
It’s important to discuss what safe limits are with your doctor as this will vary with your age and size.
arthritis and agehow to arthritis and age for If you’re sexually active, there are some things you should know about certain drugs.
Women shouldn’t take methotrexate if they are pregnant or trying for a baby, as it can be harmful for an unborn baby.
Women taking methotrexate should use contraception or encourage their partner to do so, and should carry on using contraception for three months after stopping methotrexate. If you become pregnant while taking methotrexate, you should stop taking it and see your doctor as soon as possible.
Previously it was recommended that men stop taking methotrexate three months before trying for a baby, but research has now been done that suggests that they may not need to.
Talk to your rheumatology team if you have any questions or concerns about having sex while on drugs for arthritis.
There are drugs for arthritis that are safe to take during pregnancy, and it’s important that if a woman is pregnant, her arthritis is under control.
If you’d like to start a family, it’s a good idea to talk to your rheumatology team before about what drugs you can take.

Physiotherapy and occupational therapy
- help your arthritis
- relieve pain
- improve your ability to get on with life
- provide exercises to stretch soft tissues and build up muscles
- improve your heart and lung fitness.
Your physiotherapist and occupational therapist will assess you and will develop a programme for your individual needs so that you’re able to do the activities you want and need to be able to do in your daily life. They may give you exercises and coping strategies and sometimes they may provide equipment to make daily activities easier.
Physiotherapists will help you with daily exercise by giving you a plan to follow that suits your needs. Your exercise plan will aim to make your muscles stronger and more flexible, which may help prevent damage to your joints and improve your movement. If you have a flare-up or a specific joint problem your physiotherapist will help you to improve or regain your strength.
Your therapists can provide equipment to help with your daily routine of washing and getting ready. An occupational therapist can give advice and provide equipment to help you be independent – for example, an aid to get in and out of the bath, if necessary.
There are various ways to relieve pain, such as hot and cold pads, TENS, acupuncture, massage, hydrotherapy and relaxation. Your physiotherapist will be able to advise you on these.
If your sleep is affected, it’s good to have a regular routine and some method of pain relief before bed.
arthritis and agehow to arthritis and age for A good upright posture is important to keep your body working efficiently. This means keeping the muscles strong enough to keep the back straight, with the shoulders relaxed but held back and the head up. This is particularly important when you’re sitting using a computer.
Your therapists can give you tips to improve your posture and exercises to strengthen the ‘core’ of your body (the muscles of your stomach and back).
Splints and insoles
Splints will help stabilise your joints and give support to allow you to keep going for longer periods.
A podiatrist will be able to provide you with insoles, which will give added support to your feet and ankles and can often help to relieve pain in your knees and hips.
Protecting your joints
It’s important to be aware of joint protection. The muscles and soft tissues which hold your joints in place can be put under strain as you use them. Use supports for the joints if necessary and ensure that your muscles are as strong as possible. Your therapists will give you advice about the best ways to protect your joints when out and about or performing certain tasks.
Most young people with JIA have normal mobility. However, you may need to allow extra time to get from place to place, especially if you have to use stairs. You may need crutches to help with walking, or a wheelchair if walking distances becomes a problem.
Your therapy team will advise you on what mobility aids you may need and give you tips for getting about.
To ensure you get the right wheelchair for your needs an assessment will be necessary. Remember that a wheelchair is an aid to your mobility, not a replacement for it.
Some young people with severe arthritis will benefit from surgery when other treatments haven’t helped. However, such procedures are now much rarer due to the more effective drug therapies available.

Try to set aside 15–20 minutes each day to work out. This doesn’t need to be too energetic but you should check that each joint in your neck, spine, arms and legs moves fully. As your arthritis becomes controlled and your general fitness improves you can make the exercises a bit harder.
Your diet is very important when you’re growing up as it keeps you healthy and makes your bones strong. It’s important to take steps when you’re young to help prevent osteoporosis in the future.
