🦴 Chapter A1 – Module 8: Arthritis

 

Arthritis is a group of conditions that affect the joints, causing:

• Pain
• Stiffness
• Swelling
• Reduced movement

There are 100+ types, but the most common are:

• Osteoarthritis
• Rheumatoid Arthritis

---

🧠 What Happens in Arthritis?

Joints are where bones meet, and they are protected by cartilage (a smooth cushioning tissue).

In arthritis:

• Cartilage may wear down
• The immune system may attack the joint
• Inflammation causes pain and swelling

---

🧩 Types and Causes of Arthritis

🦴 Osteoarthritis (Wear-and-Tear)

• Cartilage breaks down over time
• Bones may rub together
• Common in knees, hips, and hands

---

🧠 Rheumatoid Arthritis (Autoimmune)

• The immune system attacks healthy joints
• Causes inflammation and joint damage
• Can affect other organs (e.g. lungs, eyes)

---

💎 Gout

• Caused by uric acid crystal buildup
• Often affects the big toe
• Sudden, severe pain episodes

---

⚠️ Other Causes

• Joint injury (post-traumatic arthritis)
• Infection (septic arthritis)
• Genetic conditions

---

⚠️ Common Symptoms

🦴 Joint Symptoms

• Persistent pain
• Stiffness (often worse in the morning)
• Swelling and warmth
• Reduced movement
• Clicking or grinding (crepitus)

---

🧠 Whole-Body Symptoms (especially inflammatory types)

• Fatigue
• Fever
• General feeling of illness

---

⚠️ Risk Factors

You may be more at risk if you have:

• 👵 Age – risk increases over time
• ⚖️ Weight – extra pressure on joints
• 🏃 Injury history – sports or accidents
• 🧬 Genetics – family history
• 🚬 Smoking – linked to autoimmune arthritis
• 💼 Occupation – repetitive movement or heavy lifting

---

🧠 How Arthritis Affects Daily Life

Arthritis can impact:

• Walking and movement
• Work and daily tasks
• Sleep (due to pain)
• Mental health (frustration, low mood)

---

⚖️ Progression and Prognosis

• Many types are chronic (long-term)
• Symptoms may worsen over time
• Early treatment can slow progression
• Without support, joints may become damaged or deformed

---

🏥 Treatment and Management

There is no cure for most types, but treatment helps manage symptoms and improve quality of life.

---

💊 Medication

• Pain relievers (analgesics)
• Anti-inflammatory drugs (NSAIDs)
• Immune-modifying drugs (for RA)

---

🧘 Physical Therapy

• Improves movement and flexibility
• Strengthens muscles around joints
• Reduces stiffness

---

🥗 Lifestyle Support

• Weight management
• Low-impact exercise (walking, swimming)
• Joint protection techniques

---

🏥 Surgery

• Joint repair or replacement (arthroplasty)
• Often used in severe cases

---

🤝 Everyday Coping Strategies

• Use supportive aids (braces, walking aids)
• Pace activities (don’t overdo it)
• Apply heat or cold therapy
• Stay active but avoid strain

---

🧠 Key Understanding

Arthritis is:

• A long-term condition affecting joints
• Not just “wear and tear” — some types are autoimmune
• Manageable with the right support
• Different for every person
