🔍 Quick Summary
Arthritis is inflammation of the joints causing pain and stiffness.
It is common and manageable—but early care helps protect joint function.
1️⃣ Introduction
Arthritis refers to conditions affecting the joints.
• joints connect bones and allow movement
• inflammation leads to pain and stiffness
• can affect one or multiple joints
👉 Arthritis is not a single disease—it includes many types.
2️⃣ How it happens
Joint structures become inflamed or damaged.
• cartilage (joint cushion) may wear down
• immune system may attack joints
• fluid and swelling increase
👉 This disrupts smooth movement and causes pain.
3️⃣ Types
- “wear and tear” of joints
- common with aging
- autoimmune condition
- immune system attacks joints
• Other types
- gout
- psoriatic arthritis
- ankylosing spondylitis
- juvenile idiopathic arthritis
👉 There are many types of arthritis, and each has different causes, symptoms and treatments.
4️⃣ Common causes
• Degenerative factors
- aging
- joint overuse
• Other causes
- autoimmune diseases (eg RA)
- previous injury
- infections (less common)
- uric acid crystal build-up (gout)
👉 The cause depends on the type of arthritis. Some types develop with age and joint wear, while others are caused by the immune system, infections or crystal deposits.
5️⃣ Symptom
• joint pain
• stiffness (especially in the morning)
• reduced movement
👉 Symptoms occur due to inflammation and joint damage.
6️⃣ Associated symptoms
• swelling around joints
• warmth or redness
• fatigue (especially in autoimmune types)
• joint deformity (late stages)
👉 Symptoms may worsen over time without treatment.
7️⃣ 🩺When it becomes dangerous 🚨
• severe joint pain or swelling
• rapid worsening of symptoms
• inability to move the joint
👉 These may indicate:
• active inflammation or joint damage
• need for medical evaluation
8️⃣ Management / treatment
• physical activity and joint exercises
• medications to reduce pain/inflammation
• lifestyle adjustments
9️⃣ Diagnosis
• clinical assessment
• imaging (X-ray, MRI)
• blood tests (for some types)
👉 Diagnosis depends on type and pattern.
🟢 Important message
Arthritis is common—but manageable.
👉 Early treatment helps maintain mobility and quality of life.
