Living With Arthritis? You’re Not Alone

Arthritis is an umbrella used to describe a group of conditions that primarily affect the joints, leading to inflammation, pain, stiffness, and reduced mobility. Rather than being a single disease, arthritis includes more than 100 different disorders that vary in cause, severity, and progression. Some forms develop due to gradual wear and tear on the joints, while others occur when the immune system mistakenly attacks healthy joint tissues.

Arthritis can affect people of all ages, including children and young adults, and may involve one joint or multiple joints throughout the body. Over time, untreated or poorly managed arthritis can interfere with daily activities such as walking, writing, working, and even sleeping. Early awareness, accurate diagnosis, and personalized management play a crucial role in maintaining joint health and long-term quality of life.

Types of Arthritis

Each type affects the joints differently, with unique causes, symptoms, and treatment approaches.

Osteoarthritis (OA)

Osteoarthritis (OA)

  • Cartilage wear and tear
  • Age-related joint degeneration
  • Common in knees, hips
  • Activity-related pain
Rheumatoid Arthritis (RA)

Rheumatoid Arthritis (RA)

  • Autoimmune joint inflammation
  • Symmetrical joint involvement
  • Morning stiffness common
  • Progressive joint damage
Ankylosing Spondylitis (AS)

Ankylosing Spondylitis (AS)

  • Spine-focused inflammation
  • Lower back stiffness
  • Improves with movement
  • Postural changes over time
Psoriatic Arthritis (PsA)

Psoriatic Arthritis (PsA)

  • Linked with psoriasis
  • Joint and skin involvement
  • Nail changes common
  • Flare-based symptoms
Reactive Arthritis

Reactive Arthritis

  • Triggered by infection
  • Affects joints, eyes
  • Develops weeks later
  • Often temporary course
Enteropathic Arthritis

Enteropathic Arthritis

  • Associated with IBD
  • Gut-joint connection
  • Fluctuates with flares
  • Peripheral or spinal pain
Gout

Gout

  • Uric acid crystals
  • Sudden severe pain
  • Often affects big toe
  • Diet-related triggers
Juvenile Idiopathic Arthritis (JIA)

Juvenile Idiopathic Arthritis (JIA)

  • Childhood-onset arthritis
  • Persistent joint inflammation
  • Growth impact possible
  • Early treatment essential
Lupus-Related Arthritis

Lupus-Related Arthritis

  • Autoimmune systemic disease
  • Migratory joint pain
  • Less joint damage
  • Fatigue common
Septic Arthritis

Septic Arthritis

  • Joint infection present
  • Rapid symptom onset
  • Severe pain and swelling
  • Medical emergency

Causes and Risk Factors of Arthritis

Understanding what contributes to arthritis can help with early prevention, timely diagnosis, and better long-term joint care.

Key Causes

  • Cartilage wear with age
  • Autoimmune-driven inflammation
  • Post-infection joint response
  • Uric acid crystal buildup
  • Injury or repetitive strain

Risk Factors

  • Aging and joint wear
  • Family history
  • Excess body weight
  • Smoking, low activity
  • Repetitive work stress

Symptoms of Arthritis

Symptoms can range from mild discomfort to severe disability and may fluctuate over time depending on the type and severity of arthritis.

How Is Arthritis Diagnosed?

Diagnosing arthritis involves a comprehensive evaluation to identify the specific type and severity of the condition.

  • Review of medical history and symptom patterns
  • Physical examination assessing joint swelling, tenderness, and mobility
  • Blood tests to detect inflammation markers or autoimmune antibodies
  • Imaging studies such as X-rays, MRI, or ultrasound to assess joint damage
  • Joint fluid analysis in suspected infections or crystal-related arthritis
