Arthritis

"Arthritis" literally means joint inflammation, but it's used as an umbrella term for more than 100 distinct conditions that affect the joints in different ways — including the colloquial term "rheumatism," which is largely synonymous with arthritis in everyday usage rather than a distinct medical diagnosis.

The Main Types

Osteoarthritis, the most common type, is caused by gradual cartilage breakdown from wear over time — our knee osteoarthritis guide covers the most commonly affected joint in depth.

Inflammatory arthritis (such as rheumatoid arthritis) is an autoimmune condition where the immune system mistakenly attacks the joints, causing inflammation, and typically needs different treatment than osteoarthritis.

Gout, a distinct type caused by uric acid crystal buildup, has its own dedicated gout guide given how different its triggers and treatment are from the other types.

A regionally relevant cause worth knowing: recurrent joint attacks, especially in children or young adults, can also stem from Familial Mediterranean Fever, a hereditary condition more common in this part of the world — distinct from osteoarthritis and typically identified by its accompanying fever pattern rather than joint imaging alone.

General Symptoms Across Types

Joint pain, stiffness, swelling, and reduced range of motion are common across most types of arthritis, though the specific pattern (which joints, how symmetric, how quickly it develops) helps distinguish between them.

General Approach to Treatment

Treatment depends heavily on the specific type — osteoarthritis focuses on weight management, exercise, and pain control, while inflammatory types like rheumatoid arthritis require medications that target the immune system. This is why an accurate diagnosis, rather than assuming "arthritis" is one single condition, matters for effective treatment.

When to Seek Prompt Evaluation

Morning joint stiffness lasting more than an hour, rather than easing within around thirty minutes, is also a useful clue pointing toward inflammatory arthritis rather than typical osteoarthritis, and is worth discussing with a doctor.
