Osteoarthritis: symptoms, causes, stages, treatment, diet and prevention

Osteoarthritis is the most common form of arthritis and can affect much more than just the cartilage inside a joint. It can gradually cause pain, stiffness, swelling, reduced flexibility and difficulty with everyday activities such as walking, climbing stairs, bending or gripping objects.

The condition most often affects the knees, hips, hands and spine, although almost any joint can be affected. Osteoarthritis becomes more common with age, but getting older is not the only reason it develops. Previous joint injuries, excess body weight, repetitive stress, genetics and certain medical conditions can also increase the risk.

The good news is that osteoarthritis can often be managed effectively. Regular physical activity, maintaining a healthy weight, strengthening the muscles around affected joints, appropriate medicines and other treatments can help reduce pain and preserve mobility.

What is osteoarthritis?

Osteoarthritis is a chronic joint condition in which the cartilage and other tissues within a joint gradually change and become damaged.

Healthy cartilage provides a smooth, protective surface over the ends of bones. It helps bones move against each other with minimal friction and absorbs some of the forces placed on the joint.

With osteoarthritis, cartilage becomes thinner and less effective. Changes can also occur in the underlying bone, joint lining, ligaments and other surrounding tissues. Bone spurs, known as osteophytes, may develop around the joint.

Osteoarthritis is therefore more than simple “wear and tear.” It involves changes throughout the joint.

Although osteoarthritis is a long-term condition and currently has no cure that restores lost cartilage, treatment can reduce symptoms, improve function and help people remain active.

What are the symptoms of osteoarthritis?

Osteoarthritis symptoms usually develop gradually. They can vary considerably from one person to another depending on the joint affected and the severity of the disease.

Common symptoms include:

• Joint pain: Pain may occur during or after movement and can become more persistent as osteoarthritis progresses.
• Stiffness: Stiffness is often noticeable after waking up or after sitting or resting for a while.
• Swelling: The area around an affected joint may become swollen or puffy.
• Tenderness: The joint may hurt when pressure is applied.
• Reduced flexibility: You may find that you cannot move the joint as freely as before.
• Crackling or grinding: Some people hear or feel clicking, popping, grinding or grating when moving the joint.
• Bone spurs: Bony growths can develop around affected joints.
• Joint instability: An affected joint, particularly the knee, may feel weak or as though it could give way.
• Changes in joint shape: Advanced osteoarthritis can alter the appearance or alignment of a joint.

Knee osteoarthritis may make walking, climbing stairs, squatting or getting up from a chair difficult. Hip osteoarthritis can cause pain around the hip, groin or thigh. Osteoarthritis of the hands can interfere with gripping, writing or opening containers.

Symptoms may also affect sleep, mood and overall quality of life when pain becomes persistent.

What is the main cause of osteoarthritis?

There isn’t one single cause of osteoarthritis.

The main underlying process is progressive damage and structural change within the joint, particularly involving cartilage. However, several factors can contribute to this process.

Age

Age is one of the strongest risk factors. As people grow older, changes accumulate within their joints, increasing the likelihood of osteoarthritis.

However, osteoarthritis is not an inevitable part of ageing. Many older adults do not develop significant symptoms.

Previous joint injury

A previous fracture, ligament injury, meniscus injury or other joint trauma can increase the risk of developing osteoarthritis later.

This is sometimes called secondary osteoarthritis because there is an identifiable factor that has contributed to joint damage.

Excess body weight

Being overweight or obese increases the mechanical load placed on weight-bearing joints such as the knees and hips. Fat tissue may also contribute to inflammatory processes within the body.

For people who are overweight, even modest weight loss can reduce pressure on weight-bearing joints and may improve symptoms.

Repetitive joint stress

Occupations, activities or sports involving repetitive movements or prolonged loading of the same joint may increase risk.

Genetics

Some people inherit characteristics that make them more susceptible to osteoarthritis.

Joint structure and other medical conditions

Abnormal joint structure, certain metabolic conditions and other forms of arthritis can also increase the risk.

So, if you are asking, “What is the major cause of osteoarthritis?”, the most accurate answer is that age-related joint changes are a major risk factor, but osteoarthritis usually results from a combination of biological, mechanical, genetic and lifestyle factors.

At what age does osteoarthritis start?

Osteoarthritis can occur at almost any age, but the risk increases substantially as people get older.

The World Health Organization reports that typical onset is often in the late 40s to mid-50s, although younger people can develop osteoarthritis, particularly after joint injuries or because of structural or genetic factors.

It is also more common in women, particularly after menopause.

Therefore, there is no single age at which osteoarthritis “starts.” A person in their 30s can develop it after a significant injury, while another person may not experience symptoms until much later in life.

What are the stages of osteoarthritis?

Osteoarthritis doesn’t always progress in exactly the same way for everyone. Doctors may describe severity using symptoms, physical examination and imaging findings.

For knee osteoarthritis, a commonly used radiographic classification is the Kellgren-Lawrence system, which describes grades from 0 to 4.

Stage 1: Minimal or very early changes

There may be little or no noticeable symptoms. Imaging may show questionable or very early changes.

Stage 2: Mild osteoarthritis

Small bone spurs may appear and there may be early narrowing of the joint space. Some people begin experiencing pain, stiffness or discomfort during activity.

Stage 3: Moderate osteoarthritis

Cartilage loss and joint-space narrowing become more apparent. Pain and stiffness may occur more frequently, and activities such as walking, climbing stairs, squatting or bending may become increasingly difficult.

Stage 4: Severe osteoarthritis

There may be significant joint-space narrowing, large bone spurs, changes in the underlying bone and considerable loss of joint function. Pain can become persistent and movement may be severely restricted.

Importantly, X-ray severity and symptoms do not always match perfectly. Someone with significant changes on an X-ray may have relatively little pain, while another person with less obvious imaging changes may experience substantial symptoms.

How is osteoarthritis diagnosed?

Doctors generally diagnose osteoarthritis using a combination of your medical history, symptoms and physical examination.

They may assess:

• Where the pain occurs
• When the pain appears
• Joint stiffness and range of movement
• Swelling or tenderness
• Joint stability
• Changes in walking or movement
• Previous injuries or surgeries

An X-ray is commonly used when imaging is needed. It can show narrowing of the space between bones and bone spurs.

An MRI is not routinely required to diagnose osteoarthritis, but it can be useful in selected cases when doctors need more information about cartilage, ligaments, menisci or other soft tissues.

Blood tests do not diagnose osteoarthritis directly. They may sometimes be used to rule out other causes of joint pain, such as rheumatoid arthritis or gout.

What are the best treatments for osteoarthritis?

There is no single “best treatment” for everyone. Treatment depends on the affected joint, severity of symptoms, age, overall health, activity level and personal goals.

The strongest approach is usually a combination of lifestyle measures, exercise, physical therapy and medicines when needed.

Exercise and physical therapy

Regular, appropriate exercise is one of the most important parts of osteoarthritis management.

A physiotherapist can recommend exercises to:

• Strengthen muscles around the joint
• Improve flexibility
• Maintain joint movement
• Improve balance and stability
• Reduce stiffness
• Improve physical function

Low-impact activities such as walking, cycling, swimming and water-based exercise may be suitable for many people.

Exercise should be adapted to your condition rather than stopped completely because of osteoarthritis.

Weight management

If you are overweight, gradual weight loss can reduce the mechanical load on weight-bearing joints and may improve pain and mobility.

A healthy diet combined with regular physical activity is generally more useful than relying on restrictive diets or supplements.

Pain-relieving medicines

Medicines may be recommended when lifestyle measures alone are not enough.

Depending on the individual situation, doctors may consider:

• Topical non-steroidal anti-inflammatory drugs (NSAIDs)
• Oral NSAIDs
• Paracetamol/acetaminophen in selected circumstances
• Duloxetine for certain people with chronic osteoarthritis pain
• Corticosteroid injections for selected joints and situations

There is no universally “best drug” for osteoarthritis pain.

For example, topical NSAIDs can be particularly useful for knee osteoarthritis because they can provide pain relief with less whole-body exposure than oral NSAIDs. Oral NSAIDs can also be effective but are not appropriate for everyone because they may increase the risk of stomach, kidney or cardiovascular complications.

Always discuss regular painkiller use with a healthcare professional, especially if you have kidney disease, stomach ulcers, cardiovascular disease, high blood pressure or take blood-thinning medicines.

Injections and surgery

A corticosteroid injection into an affected joint may provide short-term relief for some people.

When severe osteoarthritis causes persistent pain and major limitations despite appropriate non-surgical treatment, joint replacement surgery may be considered. Knee and hip replacement are common examples.

Is walking good for osteoarthritis?

Yes. Walking is generally good for osteoarthritis, provided the amount and intensity are appropriate for your symptoms.

Regular walking can help maintain joint movement, strengthen supporting muscles, improve fitness and prevent the loss of function that can occur with inactivity.

If walking causes significant or persistent pain, the answer is not necessarily to stop all movement. Instead, reduce the duration or intensity and speak with a healthcare professional or physiotherapist about modifying your activity.

Other low-impact activities, such as cycling or swimming, may be useful alternatives.

What foods are good for osteoarthritis?

There is no single food that can reverse osteoarthritis or rebuild severely damaged cartilage.

However, a balanced, minimally processed diet can support a healthy body weight and overall health. A Mediterranean-style eating pattern is often a useful model.

Foods to include regularly may include:

• Colourful vegetables
• Leafy greens
• Broccoli, cauliflower and other cruciferous vegetables
• Fresh fruits and berries
• Whole grains
• Beans, lentils and other legumes
• Nuts and seeds
• Healthy fats such as olive oil
• Adequate protein
• Yogurt or other suitable dairy products, if tolerated

For people who eat fish, oily fish such as salmon, sardines and mackerel provide omega-3 fatty acids.

For vegetarians, useful sources of plant-based protein and healthy fats include lentils, chickpeas, beans, soy foods, walnuts, chia seeds and flaxseeds.

The overall dietary pattern matters more than any individual “arthritis food.”

What foods should you avoid with osteoarthritis?

There is no universally prohibited food list for osteoarthritis.

However, it is sensible to limit foods that are high in added sugar, heavily processed carbohydrates, unhealthy fats and excess calories.

Examples include:

• Sugary drinks
• Excess sweets and desserts
• Highly processed snack foods
• Deep-fried foods
• Processed meats
• Excess refined carbohydrates
• Foods high in saturated fat
• Excessively calorie-dense foods that contribute to weight gain

Red meat does not necessarily need to be completely eliminated, but reducing excessive consumption and replacing some servings with legumes, vegetables, nuts, seeds or other healthier protein sources can improve overall diet quality.

There is also limited scientific evidence that vegetables such as tomatoes, potatoes, peppers or eggplant need to be avoided simply because they belong to the nightshade family. Unless a particular food clearly causes symptoms for you, there is generally no reason to eliminate nutritious foods unnecessarily.

What vitamin is good for osteoarthritis?

Vitamin D is important for bone health, but it should not be considered a cure or proven pain treatment for osteoarthritis.

People who are deficient in vitamin D may need supplementation, depending on their blood levels and medical circumstances. However, research has not consistently shown that taking vitamin D supplements relieves osteoarthritis pain in people who are not deficient.

Other vitamins and minerals are also important for general health, but taking high-dose supplements does not automatically improve osteoarthritis.

Before starting vitamin or mineral supplements, particularly in high doses, discuss them with your doctor.

What foods help fight osteoarthritis?

Rather than searching for one “superfood,” focus on a pattern of eating that supports healthy weight and overall health.

Good choices include:

• Berries and other colourful fruits
• Green leafy vegetables
• Broccoli and other cruciferous vegetables
• Beans and lentils
• Whole grains
• Nuts and seeds
• Garlic and onions
• Healthy oils such as extra virgin olive oil
• Yogurt or other nutritious dairy foods when appropriate
• Fish for people who eat seafood

These foods provide fibre, vitamins, minerals, antioxidants and healthy fats. Some also contain compounds being studied for their potential effects on inflammation and joint health.

How can you avoid osteoarthritis?

Osteoarthritis cannot always be prevented, particularly when genetics, ageing or previous injuries play a role.

However, several habits can reduce risk or help protect joint function:

1. Maintain a healthy body weight.
2. Stay physically active.
3. Strengthen the muscles surrounding major joints.
4. Avoid unnecessary repetitive stress on joints.
5. Use appropriate technique and protective equipment during physical activity.
6. Treat significant joint injuries properly.
7. Maintain good overall nutrition.
8. Avoid prolonged inactivity.
9. Address medical conditions that may affect joint health.
10. Seek medical advice if persistent joint pain or swelling develops.

The goal isn’t to avoid using your joints. In fact, appropriate movement is generally beneficial. The goal is to keep joints strong, mobile and appropriately loaded.

What’s the best natural remedy for osteoarthritis?

There is no single natural remedy that can cure osteoarthritis.

The most useful “natural” approach is a combination of regular appropriate exercise, muscle strengthening, healthy weight management, good sleep and a nutritious diet.

Heat may help stiffness, while cold packs may help some people with pain or swelling after activity.

Gentle stretching, yoga or tai chi may also help some people improve movement and manage symptoms.

Supplements such as glucosamine, chondroitin and various herbal products are widely marketed for osteoarthritis. However, evidence for many of these products is inconsistent, and some can interact with medicines.

Natural does not automatically mean safe or effective.

Is osteoarthritis serious?

Osteoarthritis is not usually life-threatening, but it can become a serious health problem if it causes persistent pain, severe mobility limitations or disability.

Severe osteoarthritis may make routine activities difficult and can lead people to become less physically active. Reduced activity can contribute to muscle weakness, weight gain and poorer overall health.

Pain can also affect sleep, mood, work and social activities.

The important point is that osteoarthritis does not mean you have to give up an active life. Early attention to symptoms and a long-term management plan can make a substantial difference.

Can you live a long life with osteoarthritis?

Yes. Osteoarthritis itself is not generally considered a condition that prevents someone from living a long life.

The bigger concern is how severe symptoms affect physical activity, mobility and overall health.

Keeping active within your abilities, maintaining a healthy weight, managing cardiovascular risk factors, eating well and following an appropriate treatment plan can help protect your general health while managing osteoarthritis.

If pain is making you progressively less active, don’t simply accept it as an unavoidable part of ageing. Talk to a healthcare professional about ways to improve pain and function.

Frequently asked questions about osteoarthritis

What is the main cause of osteoarthritis?

Age-related changes within the joint are a major risk factor, but osteoarthritis usually develops because of several factors. Previous joint injuries, excess body weight, repetitive stress, genetics, abnormal joint structure and certain medical conditions can all contribute.

What are the symptoms of osteoarthritis?

The most common symptoms are joint pain, stiffness, swelling, tenderness, reduced flexibility and crackling or grinding sensations. Some people may also develop bone spurs, joint instability or changes in joint shape.

What are the stages of osteoarthritis?

Osteoarthritis is often described as mild, moderate or severe. For knee osteoarthritis, X-rays may also be classified using the Kellgren-Lawrence grading system, which ranges from grade 0 to grade 4.

What are the best treatments for osteoarthritis?

Treatment may include exercise, physiotherapy, weight management, pain-relieving medicines, topical or oral NSAIDs, selected injections and, in severe cases, joint replacement surgery. The best combination depends on the individual.

Is walking good for osteoarthritis?

Yes. Walking is generally beneficial because it keeps joints moving and helps maintain muscle strength and fitness. However, the duration and intensity should be adjusted if walking significantly aggravates symptoms.

What food should I avoid if I have arthritis?

There is no universal arthritis food ban. It is generally sensible to limit highly processed foods, excess added sugar, deep-fried foods and foods high in saturated fat, particularly when they contribute to weight gain.

What vitamin is good for osteoarthritis?

Vitamin D is important for bone health, especially when someone is deficient. However, vitamin D supplements have not consistently been shown to relieve osteoarthritis pain in people who have adequate vitamin D levels.

What is the best drug for osteoarthritis pain?

There is no single best drug for everyone. Topical NSAIDs can be effective for some people with knee osteoarthritis, while oral NSAIDs, paracetamol/acetaminophen, duloxetine or injections may be considered in selected patients. Medication should be chosen based on individual risks and health conditions.

At what age does osteoarthritis start?

Osteoarthritis becomes more common with age and often develops from middle age onward, but it can occur in younger adults, particularly after significant joint injuries or because of genetic or structural factors.

How can I avoid osteoarthritis?

Not every case can be prevented. Maintaining a healthy weight, staying active, strengthening muscles, avoiding unnecessary repetitive joint stress and properly treating joint injuries can help reduce risk and protect joint function.

What foods help fight osteoarthritis?

A balanced diet rich in vegetables, fruits, whole grains, legumes, nuts, seeds and healthy fats is a good foundation. Berries, broccoli, leafy greens, beans, nuts and olive oil are nutritious choices. Fish can provide omega-3 fatty acids for people who eat seafood.

What’s the best natural remedy for osteoarthritis?

There is no natural cure for osteoarthritis. Regular appropriate exercise, muscle strengthening, maintaining a healthy weight, nutritious eating, adequate sleep and heat or cold therapy when appropriate can help manage symptoms.

Is osteoarthritis serious?

It can be. Although it is not usually life-threatening, severe osteoarthritis can cause chronic pain, reduced mobility and disability. Early assessment and appropriate management can help maintain independence and quality of life.

When should you see a doctor?

See a healthcare professional if joint pain or stiffness persists, keeps returning or begins interfering with normal activities.

You should also seek medical advice if a joint becomes significantly swollen, suddenly painful, unstable, red or warm, or if symptoms develop after an injury.

Persistent joint symptoms should not automatically be assumed to be osteoarthritis. Conditions such as rheumatoid arthritis, gout, infections and ligament or meniscus problems can produce similar symptoms and require different treatment.

The bottom line

Osteoarthritis is a common, long-term joint condition, but it does not have to mean a life of constant pain or inactivity.

Age is an important risk factor, but previous injuries, excess weight, genetics and repeated joint stress can also contribute. Symptoms commonly include pain, stiffness, swelling, reduced flexibility and grinding or crackling sensations.

The most effective approach is usually comprehensive: stay physically active, strengthen the muscles around affected joints, maintain a healthy weight, eat a balanced diet and use appropriate medical treatments when necessary.

There is no miracle food, vitamin or natural remedy that can reverse osteoarthritis. Likewise, there is no single medicine that is best for everyone. Treatment should be personalised according to the joint involved, severity of symptoms, overall health and individual needs.

If osteoarthritis is affecting your ability to walk, work, exercise or enjoy everyday activities, getting an appropriate assessment is an important first step.
