Arthritis and other rheumatic diseases are common conditions that cause pain, swelling, stiffness, and limited movement. They affect the joints and connective tissues throughout the body. Millions of people worldwide live with different forms of arthritis.
Arthritis means inflammation of a joint. A joint is where two or more bones meet. There are more than 100 different types of arthritis and rheumatic diseases. These conditions may affect joints, muscles, tendons, ligaments, and bones. Arthritis is often chronic, meaning it can last for a long time.
Arthritis and rheumatic diseases are more common in women than men and are often associated with aging, although they can affect people of all ages.
Common Types of Arthritis
Osteoarthritis (Degenerative Arthritis)
This is the most common type of arthritis. It is a chronic joint disease that mainly affects weight-bearing joints such as:
- Knees
- Hips
- Spine
Osteoarthritis damages the cartilage covering the ends of bones, reducing joint space and causing pain, stiffness, and decreased movement. Bone spurs may also develop over time. It commonly occurs with aging but may also appear in younger people after injury or repetitive stress.
Rheumatoid Arthritis
Rheumatoid arthritis is an inflammatory autoimmune disease affecting the lining of the joints. The immune system attacks healthy tissues, causing inflammation that may involve:
- Multiple joints
- Heart
- Lungs
- Other organs
Other Rheumatic Diseases
Gout
Gout occurs when uric acid crystals build up inside joints, especially the big toe. It causes sudden severe pain, swelling, and inflammation.
Lupus
Lupus is a chronic autoimmune disorder that causes periods of inflammation affecting joints, tendons, skin, and organs.
Scleroderma
This autoimmune disease causes thickening and hardening of the skin and connective tissues.
Ankylosing Spondylitis
This condition causes inflammation in the spine and may lead to fusion of spinal bones. It can also affect the shoulders, hips, ribs, hands, and feet.
Juvenile Idiopathic Arthritis (JIA)
A form of arthritis affecting children that causes joint inflammation and stiffness. Some children improve with age, while others may experience long-term effects on bone growth.
Causes of Arthritis
The causes vary depending on the type:
- Osteoarthritis results from wear and tear over time or overuse.
- Rheumatoid arthritis, lupus, and scleroderma occur when the immune system attacks the body’s own tissues.
- Gout results from crystal buildup inside joints.
- Some forms are linked to genetic factors.
Risk Factors
Non-Modifiable Risk Factors
- Age
- Female gender
- Family history and genetics
Modifiable Risk Factors
- Excess body weight
- Previous joint injuries
- Certain infections
- Repetitive work activities
Symptoms of Arthritis
Symptoms may vary depending on the condition, but common symptoms include:
- Persistent or recurring joint pain
- Joint swelling
- Warmth and redness
- Stiffness
- Difficulty moving joints normally
Diagnosis
Diagnosis usually includes:
- Medical history
- Physical examination
- Blood tests
- X-rays or imaging studies
- Joint fluid analysis
- MRI or CT scans when needed
Common laboratory tests include:
- ANA test
- CBC
- Rheumatoid factor (RF)
- CCP antibodies
- Uric acid levels
- ESR (sedimentation rate)
Treatment of Arthritis
Treatment depends on:
- Type of arthritis
- Severity
- Patient age and overall health
There is no complete cure for most forms of arthritis, but treatment focuses on:
- Reducing pain and inflammation
- Preserving joint function
- Improving quality of life
Non-Surgical Treatment
Medications
- Pain relievers
- Anti-inflammatory medications
- Disease-modifying medications (DMARDs)
- Steroid medications
Lifestyle Modifications
- Weight loss
- Activity modification
- Exercise and stretching
Physical Therapy
Physical therapy helps improve:
- Joint flexibility
- Muscle strength
- Balance and movement
Supportive Devices
- Braces
- Splints
- Walking aids
Other Treatments
- Ice and heat therapy
- TENS therapy
- Cortisone injections
- Hyaluronic acid injections
- Acupuncture
Surgical Treatment
Surgery may be considered when conservative treatment fails.
Options include:
- Joint debridement
- Joint fusion
- Joint replacement surgery
Recovery after joint surgery may take several months and usually includes rehabilitation and physical therapy.
Living with Arthritis
Although arthritis has no permanent cure, many patients can manage symptoms successfully through:
- Regular low-impact exercise
- Maintaining a healthy weight
- Balancing activity and rest
- Using assistive devices
- Following medical treatment plans
