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. In the UK, about 15,000 children and young people are affected by arthritis.
Most types of childhood arthritis are known as juvenile idiopathic arthritis (JIA). JIA causes pain and inflammation in one or more joints for at least six 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 discussed below. Arthritis Research UK has more information about the different types of juvenile idiopathic arthritis.
Oligo-articular JIA
Oligo-articular JIA is the most common type of JIA. It affects fewer than five 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 five or more joints. It can develop at any age during childhood.
The symptoms of polyarticular JIA are similar to the symptoms of adult rheumatoid arthritis. 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
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.
Treating arthritis
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:
painkillers
non-steroidal anti-inflammatory drugs (NSAIDs)
corticosteroids
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)
Read more about how osteoarthritis is treated.
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
physiotherapy
regular exercise
Being overweight may not be as unhealthy as it was 40 years ago," BBC News reports. New research has found a body mass index (BMI) of 27 is linked to the lowest rate of death – but someone with a BMI of 27 is currently classed as being overweight. BMI is a score calculated by dividing your weight (usually in kilograms) by the square of your height (usually in metres and centimetres). Currently, a BMI of 25 to 29.9 is classified as being overweight. Researchers looked at 120,528 people from Copenhagen, recruited from 1976 to 2013, and separately compared those recruited during the 1970s, 1990s and 2000s. They were followed up until they died, emigrated, or the study finished. The BMI linked to the lowest risk of having died from any cause was 23.7 in the 1970s group, 24.6 in the 1990s group, and had further risen to 27 in the 2003-13 group. It may be the case that the suggested upward shift in optimal BMI is the result of improvements in preventative treatments for weight-rela...
