Arthritis is a broad term that describes over 100 different joint conditions, all characterized by inflammation, pain, and reduced mobility. While it is often associated with aging, arthritis can affect individuals of all ages. Understanding the root causes of arthritis is key to effective prevention and management. Dr. Amit Agarwal, a leading orthopedic surgeon at Apollo Hospital, Delhi, sheds light on the common causes of arthritis to help patients take proactive steps in protecting their joint health.
1. Age-Related Degeneration
Osteoarthritis (OA) is the most common form of arthritis, often referred to as “wear-and-tear arthritis.” This condition results from the gradual breakdown of cartilage that cushions the joints.
- Aging Factor: As we age, cartilage loses its ability to repair itself, making it more prone to wear and tear.
- Affected Joints: Weight-bearing joints like the knees, hips, and spine are most susceptible.
While aging is inevitable, maintaining an active lifestyle and a healthy weight can slow down joint degeneration.
2. Autoimmune Disorders
Autoimmune arthritis occurs when the body’s immune system mistakenly attacks healthy tissues, leading to joint inflammation and damage.
- Rheumatoid Arthritis (RA): A chronic autoimmune condition that primarily affects the hands, wrists, and knees.
- Psoriatic Arthritis: Associated with psoriasis, this condition impacts both the skin and joints.
Did You Know? Women are three times more likely than men to develop rheumatoid arthritis, often between the ages of 30 and 60.
3. Genetic Predisposition
Arthritis can run in families, particularly certain types like:
- Rheumatoid Arthritis: A family history of RA increases susceptibility.
- Ankylosing Spondylitis: A rare form of arthritis primarily affecting the spine, linked to genetic markers like HLA-B27.
While genetics play a role, lifestyle choices such as regular exercise and a balanced diet can help reduce the risk.
4. Joint Injuries and Overuse
Injuries and repetitive joint movements are significant contributors to arthritis:
- Post-Traumatic Arthritis: Occurs after joint injuries such as fractures or ligament tears.
- Repetitive Stress Injuries: Activities like typing, running, or heavy lifting can lead to cartilage wear and tear over time.
Prevention Tip: Always use proper techniques when lifting heavy objects or performing repetitive tasks.
5. Infections
Certain bacterial, viral, or fungal infections can invade the joints, leading to:
- Septic Arthritis: An acute condition caused by infections like staphylococcus or streptococcus.
- Reactive Arthritis: Triggered by infections in other parts of the body, such as the urinary tract or intestines.
Early treatment of infections can prevent long-term joint complications.
6. Metabolic Disorders
Metabolic disorders can cause specific types of arthritis, including:
- Gout: Caused by the accumulation of uric acid crystals in the joints, leading to sudden and severe pain.
- Pseudogout: Involves calcium pyrophosphate crystal deposits, commonly affecting the knees.
Maintaining a healthy diet low in purines (found in red meat and alcohol) can help manage these conditions.
7. Obesity and Joint Overload
Excess weight puts added stress on weight-bearing joints like the knees and hips, accelerating cartilage damage.
- Obesity also contributes to systemic inflammation, which can worsen autoimmune arthritis like rheumatoid arthritis.
- Losing just 10% of body weight can significantly reduce knee joint pain and the risk of osteoarthritis.
8. Hormonal Factors
Hormones play a significant role in joint health:
- Post-Menopausal Women: The drop in estrogen levels after menopause increases the risk of osteoarthritis.
- Endocrine Disorders: Conditions like hypothyroidism can also lead to joint stiffness and pain.
Including calcium and vitamin D-rich foods in your diet can support bone and joint health.
9. Nutritional Deficiencies
A lack of essential nutrients can weaken joints and bones:
- Vitamin D Deficiency: Impairs calcium absorption, affecting bone density.
- Calcium Deficiency: Increases the risk of bone thinning and joint damage.
Pro Tip: Sunlight exposure and a diet rich in dairy, leafy greens, and fortified cereals can prevent these deficiencies.
10. Chronic Health Conditions
Other medical conditions can contribute to arthritis development:
- Diabetes: Increases inflammation and susceptibility to joint damage.
- Cardiovascular Disease: Chronic inflammation associated with heart disease can affect joints.
Managing these conditions with lifestyle modifications and medications can reduce arthritis risk.
11. Lifestyle Choices and Environmental Factors
Certain habits and exposures can exacerbate arthritis symptoms:
- Smoking: Promotes inflammation and reduces the body’s ability to repair joint tissues.
- Sedentary Lifestyle: Weakens muscles that support joints, increasing stress on cartilage.
- Cold Weather: Arthritis symptoms, especially osteoarthritis, often worsen in cold, damp climates.
Frequently Asked Questions (FAQs)
Q1: Can arthritis be prevented?
- While not all types of arthritis can be prevented, maintaining a healthy lifestyle, avoiding joint injuries, and managing weight can reduce your risk.
Q2: What’s the difference between osteoarthritis and rheumatoid arthritis?
- Osteoarthritis is caused by cartilage wear and tear, while rheumatoid arthritis is an autoimmune condition.
Q3: How is arthritis diagnosed?
- Diagnosis involves a combination of physical exams, imaging tests (X-rays, MRI), and lab tests to identify inflammation markers.
