Understanding Arthritis: Types, Symptoms, and Causes

The video discusses arthritis, focusing on osteoarthritis and rheumatoid arthritis. Arthritis is a condition involving joint inflammation, with over 100 types. Osteoarthritis is common in weight-bearing joints and is linked to age, obesity, and joint injuries. Rheumatoid arthritis is an autoimmune disease affecting various joints, with symptoms like pain and stiffness. The video explains the differences in symptoms, affected joints, and risk factors for both types, highlighting the mechanical nature of osteoarthritis and the inflammatory nature of rheumatoid arthritis.
