What is the Difference Between Rheumatoid Arthritis and Osteoarthritis
Rheumatoid arthritis (RA) is an autoimmune disease that causes inflammation in the joints. It occurs when the immune system mistakenly attacks the tissues lining the joints. This inflammation leads to pain, stiffness, and swelling in the affected joints. RA can affect multiple joints in the body, and it tends to develop symmetrically, meaning it affects both sides of the body. It can also cause systemic inflammation, leading to flu-like symptoms such as fever.
On the other hand, osteoarthritis (OA) is primarily a degenerative joint disorder caused by wear and tear on the cartilage. It results from the typical aging process and repeated use of the joints over time. OA leads to many of the same symptoms as RA, including joint pain and stiffness, but it is not an autoimmune disease. Unlike RA, OA usually affects only a few joints in the body, and it typically develops on one side rather than both sides.
Some other differences between RA and OA include:
- RA can cause systemic inflammation and flu-like symptoms such as fever, while OA's symptoms tend to be limited to the affected joint or joints.
- The onset of pain from RA may take at least 1 hour to start easing after rest, while pain from OA often improves after activity.
If you're experiencing joint pain or stiffness, it's always best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment options.
