Arthritis is a common condition that causes pain and inflammation in a joint.
In the UK, around 10 million people have arthritis. It affects people of all ages, including children.
Types of arthritis
The 2 most common types of arthritis are:
Osteoarthritis most often develops in adults who are in their late 40s or older. It's also more common in women and people with a family history of the condition. However, it can occur at any age as a result of an injury or be associated with other joint-related conditions, such asor rheumatoid arthritis.
Osteoarthritis initially affects the smooth cartilage lining of the joint. This makes movement more difficult than usual, leading to pain and stiffness.
Once the cartilage lining starts to roughen and thin out, the tendons and ligaments have to work harder. This can cause swelling and the formation of bony spurs called osteophytes.
Severe loss of cartilage can lead to bone rubbing on bone, changing the shape of the joint and forcing the bones out of their normal position.
The most commonly affected joints are those in the:
Rheumatoid arthritis often starts when a person is between 40 and 50 years old. Women are 3 times more likely to be affected than men.
It occurs when the body's immune system targets affected joints, which leads to pain and swelling.
The outer covering (synovium) of the joint is the first place affected. This can then spread across the joint, leading to further swelling and a change in the joint's shape. This may cause the bone and cartilage to break down.
People with rheumatoid arthritis can also develop problems with other tissues and organs in their body.
Other types of arthritis and related conditions
- – a long-term inflammatory condition that mainly affects the bones, muscles and ligaments of the spine, leading to stiffness and joints fusing together. Other problems can include the swelling of tendons, eyes and large joints
- – also known as degenerative osteoarthritis, cervical spondylitis affects the joints and bones in the neck, which can lead to pain and stiffness
- – causes pain in the body's muscles, ligaments and tendons
- – an autoimmune condition that can affect many different organs and the body's tissues
- – a type of arthritis caused by too much uric acid in the body. This can be left in joints (usually affecting the big toe) but can develop in any joint. It causes intense pain, redness and swelling
- – an inflammatory joint condition that can affect people with
- – a form of chronic, inflammatory arthritis associated with inflammatory bowel disease (IBD), the 2 best-known types being and . About 1 in 5 people with Crohn's or ulcerative colitis will develop enteropathic arthritis. The most common areas affected by inflammation are the peripheral (limb) joints and the spine
- – this can cause inflammation of the joints, eyes and urethra (the tube that urine passes through). It develops shortly after an infection of the bowel, genital tract or, less frequently, after a throat infection
- secondary arthritis – a type of arthritis that can develop after a joint injury and sometimes occurs many years afterwards
- – a condition that almost always affects people over 50 years of age, where the immune system causes muscle pain and stiffness, usually across the shoulders and tops of the legs. It can also cause joint inflammation
Symptoms of arthritis
The symptoms of arthritis you experience will vary depending on the type you have.
This is why it's important to have an accurate diagnosis if you have:
- joint pain, tenderness and stiffness
- inflammation in and around the joints
- restricted movement of the joints
- warm, red skin over the affected joint
- weakness and muscle wasting
Arthritis and children
Arthritis is often associated with older people, but it can also affect children.
Most types of childhood arthritis are known as juvenile idiopathic arthritis (JIA). JIA causes pain and inflammation in 1 or more joints for at least 6 weeks.
Although the exact cause of JIA is unknown, the symptoms often improve as a child gets older, meaning they can lead a normal life.
The main types of JIA are:
Oligo-articular JIA is the most common type of JIA. It affects fewer than 5 joints in the body – most commonly in the knees, ankles and wrists.
Oligo-articular JIA has good recovery rates and long-term effects are rare. However, there's a risk that children with the condition may develop eye problems, so regular eye tests with an ophthalmologist (eye care specialist) are recommended.
Polyarticular JIA (polyarthritis)
Polyarticular JIA, or polyarthritis, affects 5 or more joints. It can develop at any age during childhood.
The symptoms of polyarticular JIA are similar to the. The condition is often accompanied by a rash and a high temperature of 38C (100.4F) or above.
Systemic onset JIA
Systemic onset JIA begins with symptoms such as a fever, rash, lethargy (a lack of energy) and enlarged glands. Later on, joints can become swollen and inflamed.
Like polyarticular JIA, systemic onset JIA can affect children of any age.
Enthesitis-related arthritis is a type of juvenile arthritis that affects older boys or teenagers. It can cause pain in the soles of the feet and around the knee and hip joints, where the ligaments attach to the bone.
There's no cure for arthritis, but there are many treatments that can help slow down the condition.
For osteoarthritis, medications are often prescribed, including:
In severe cases, the following surgical procedures may be recommended:
- arthroplasty (joint replacement)
- arthodesis (joint fusion)
- osteotomy (where a bone is cut and re-aligned)

Treatment for rheumatoid arthritis aims to slow down the condition's progress and minimise joint inflammation or swelling. This is to try and prevent damage to the joints. Recommended treatments include:
- analgesics (painkillers)
- disease-modifying anti-rheumatic drugs (DMARDs) – a combination of treatments is often recommended

Living with arthritis
Living with arthritis isn't easy and carrying out simple, everyday tasks can often be painful and difficult.
However, there are many things you can do to make sure you live a healthy lifestyle. A range of services and benefits are also available.
Many people with arthritis want to continue working for many reasons, including better financial security and higher self-esteem.
Improved treatment approaches have helped ensure that many people who are diagnosed with arthritis can return to work. This is particularly the case if arthritis is diagnosed and treated at an early stage.
You may find work challenging, but your employer should help you with the training and support you need.
Help is also available if your arthritis is so severe that you're unable to work.
It's very important to eat aif you have arthritis. Eating healthily will give you all the nutrients you need and help you maintain a healthy weight.
Your diet should consist of a variety of foods from all 5 food groups. These are:
- fruit and vegetables
- starchy foods – such as bread, rice, potatoes and pasta
- meat, fish, eggs and beans
- milk and dairy foods
- foods containing fat and sugar
If you're overweight,can really help you cope with arthritis. Too much weight places excess pressure on the joints in your hips, knees, ankles and feet, leading to increased pain and mobility problems.
If your arthritis is painful, you may not feel like exercising. However, being active can help reduce and prevent pain.can also:
- improve your range of movement and joint mobility
- increase muscle strength
- reduce stiffness
- boost your energy
As long as you do the right type and level of exercise for your condition, your arthritis won't get any worse. Combined with a healthy, balanced diet, regular exercise will help you lose weight and reduce strain on your joints.
Your doctor can advise about the type and level of exercise that's right for you.
If you have arthritis, it's important to look after your joints so there's no further damage. For example, try to reduce the stress on your joints while carrying out everyday tasks like moving and lifting.
Some tips for protecting your joints, particularly if you have arthritis, include:
- use larger, stronger joints as levers – for example, take the pressure of opening a heavy door on your shoulder rather than on your hand
- use several joints to spread the weight of an object – for example, use both hands to carry your shopping or distribute the weight evenly in a shoulder bag or rucksack
- don't grip too tightly – grip as loosely as possible or use a padded handle to widen your grip
It's also important to avoid sitting in the same position for long periods of time and to take regular breaks so you can move around.
If you have arthritis, carrying out tasks around the home can be a challenge. However, making some practical changes to your home and changing the way you work should make things easier.
Practical tips that could help include:
- keeping things in easy reach
- using a handrail to help you get up and down the stairs
- using long-handled tools to pick things up or to clean
- fitting levers to taps to make them easier to turn
- using electric kitchen equipment, such as tin openers, when preparing food
An occupational therapist can help if you have severe arthritis that's affecting your ability to move around your home and carry out everyday tasks, such as cooking and cleaning.
They can advise about equipment you may need to help you live independently.
Depending on the exact nature of your condition, your doctor may be able to refer you to an occupational therapist.
