What is Rheumatoid Arthritis?
Rheumatoid Arthritis is a chronic arthritis that can cause significant pain, swelling, stiffness and damage to joints, and can eventually lead to deformity, disability and the need for joint replacement.
Rheumatoid Arthritis is an autoimmune condition, which is when our immune system attacks itself. In the case of Rheumatoid Arthritis, our immune system attacks the ‘synovium’ (inner lining) of our joints, causing inflammation within the joint. What causes the immune system to attack our own body is unknown, but is thought to be a mix of genetic and environmental factors.
What are the symptoms of Rheumatoid Arthritis?
Common symptoms include:
Joint pain and swelling
Symmetrical joint pain distribution
Small joints usually affected (hands and feet)
Other symptoms affecting the whole body can include:
Low grade fever
Sometimes, Rheumatoid Arthritis can affect other organs like the lungs, heart and eyes.
How does Rheumatoid Arthritis differ from Osteoarthritis?
Osteoarthritis is the most common form of arthritis, with Rheumatoid Arthritis being second most common. The most important difference between them is that while Rheumatoid Arthritis is an inflammatory arthritis caused by autoimmune disease, Osteoarthritis is a mechanical arthritis caused by wear and tear. These therefore present themselves in different ways, as summarised below:
Pain worse at the end of the day
Large joints affected, asymmetrically (eg knee, hip)
Usually one or a few joints affected
Usually occurs in older patients
Hard, bony swelling of the joint
Usually continuous and progressive
Inflammatory (Rheumatoid + others)
Pain worse in the morning
Small joints affected, often symmetrically (eg hands, feet)
Often multiple joints affected
Often occurs in middle age
Soft, fluid-like swelling of the joint
Often episodic (comes and goes)
How is Rheumatoid Arthritis diagnosed?
Rheumatoid Arthritis can be diagnosed by your doctor. It can be difficult to diagnose Rheumatoid Arthritis because there is no single definitive test, however the diagnosis is likely to be based off your description of symptoms, a physical examination of the affected joints, blood tests and X-rays.
How is Rheumatoid Arthritis treated?
Rheumatoid Arthritis can be managed with a combination of medication and lifestyle measures. Your doctor will prescribe you medication to take when you get flares of arthritis to reduce pain and damage to the joint, as well as DMARDs (Disease Modifying Anti-Rheumatic Drugs) for you to take regularly to prevent the number of flares.
Along with these medications, there are certain lifestyle measures you can take to improve your quality of life with this disease:
Keep physically active
Stop smoking – There is strong evidence that smoking can exacerbate Rheumatoid Arthritis.
Maintain a healthy weight – Obesity can make joint pain related to Rheumatoid Arthritis a lot less bearable and decrease the quality of life for someone suffering from Rheumatoid Arthritis.
