Arthritis And Diet
Informed by recognized medical guidance
Overview
Arthritis is a condition that causes pain, swelling and stiffness in one or more joints. It is not a single disease but a group of conditions. Diet cannot cure arthritis, but eating certain foods and avoiding others may help manage symptoms and support joint health.
Key facts
- No single 'arthritis diet' works for everyone.
- Eating a Mediterranean-style diet – plenty of fruit, vegetables, fish and healthy oils – may help reduce inflammation.
- Keeping a healthy weight lowers the strain on weight-bearing joints like knees and hips.
Yes. Arthritis is very common. It affects millions of people of all ages worldwide, and the risk increases with age.
Arthritis can affect anyone, including children and young adults. Osteoarthritis is more common in older adults, while some types, like rheumatoid arthritis, can start in mid-adulthood. It is slightly more common in women.
Symptoms
- Sudden, severe joint swelling with a very high fever – this could be a joint infection
- A hot, red, intensely painful joint that makes it impossible to move the limb
- ⚠New joint swelling that appears quickly and does not settle within a day or two
- ⚠Severe pain that affects sleep or normal activities
- ⚠A joint that is locked and cannot straighten or bend
Common symptoms
- Joint pain
- Stiffness, especially in the morning
- Swelling, redness or warmth around a joint

Symptoms in older adults
- Aching knees, hips or hands that worsens with activity
- Morning stiffness lasting less than an hour
- Trouble with everyday tasks like climbing stairs or getting dressed
Causes
Main causes
- Osteoarthritis is caused by wear and tear on the cartilage over time.
- Rheumatoid arthritis is an autoimmune condition, where the immune system attacks the joints.
- Other types can result from infection, a build-up of uric acid (gout), or a family history of autoimmune disease.
Risk factors
- Being overweight or obese
- A previous joint injury
- Family history
- Smoking
- Having an autoimmune condition
When to see a doctor
See a doctor urgently if:
- Call your doctor or local health line for advice if you have a joint that becomes swollen, hot, or very painful overnight, or if you cannot use the joint at all.
Book a routine appointment if:
- Make an appointment if you have joint pain, swelling or stiffness that lasts longer than a few weeks, even if it is mild.
Diagnosis
A doctor will ask about your symptoms and medical history, examine your joints, and check how well they move. They may also ask about any family history of arthritis or other conditions.
Tests that may be done
- Blood tests to look for inflammation or immune markers
- X-rays to see changes in the joint spaces
- Ultrasound or MRI scans for a clearer look at the joint
- A small sample of joint fluid, if an infection is suspected
What to expect at your appointment
You do not need to have every test. The doctor may start with a simple examination and then refer you to a specialist if needed. The process may take a few weeks, but most tests are straightforward and quick.
Treatment
Treatment aims to reduce pain, improve joint movement, and slow down any joint damage. Diet, exercise, and weight control are an important part of the plan, alongside medical treatment when needed.
Self-care at home
- Keep moving with low-impact exercises like walking, swimming or cycling.
- Apply a warm or cold pack to painful joints.
- Maintain a healthy weight.
- Use supportive shoes and handrails.
- Take breaks and pace your activities.
Medical treatments
Medicines are used to control pain and inflammation. These include anti-inflammatory creams or tablets, and for some types of arthritis, medicines that calm the immune system. Treatments are chosen based on the type of arthritis and are always discussed with a doctor. Physiotherapy and daily exercise plans are also key. In some cases, steroid injections into a joint can give short-term relief.
When is surgery considered?
Surgery is considered when other treatments are not enough and the joint is badly damaged. Joint replacement, usually for hips or knees, can significantly restore movement and reduce pain.
Living with this condition
Learn how to protect your joints. Use larger joints when carrying, use assistive tools like a reacher, and plan rest breaks during busy days. If you are in a flare, do less but do not stop moving completely.
Lifestyle tips
- Quit smoking
- Limit alcohol
- Get enough sleep
- Keep your home safe to prevent falls and make daily tasks easier
Diet and exercise
For diet, focus on a Mediterranean-style plate: plenty of vegetables, fruit, whole grains, and healthy fats such as olive oil and oily fish. Limit processed foods, sugary drinks, and excess red meat. For exercise, aim for at least 30 minutes of low-impact activity most days. Start slowly and build up.
Mental health and emotional wellbeing
Living with chronic pain can lead to frustration, anxiety, and low mood. It is normal to feel this way. Talking to friends, family, a counsellor, or joining a support group can help.
Prevention
You cannot always prevent arthritis, but you can lower your risk of osteoarthritis by maintaining a healthy weight, staying physically active, and preventing joint injuries.
Vaccines
Keeping up to date with routine vaccinations, such as flu and pneumococcal vaccines, may help avoid serious infections that can trigger joint symptoms.
Screening programmes
There is no routine screening test for arthritis. However, if you have a family history and early symptoms, regular check-ups with your doctor can help catch problems early.
Complications
If left untreated
- Untreated inflammatory arthritis can lead to permanent joint damage and deformity.
- Chronic pain can lead to reduced mobility, loss of independence, and falls.
- People with inflammatory arthritis have a higher risk of heart disease, so controlling inflammation matters.
Long-term outlook
With the right treatment, lifestyle changes and a healthy diet, most people with arthritis remain active and independent. The course can be different for everyone, but seeing a doctor early and following a plan usually leads to the best outcome.
