Autoimmune diseases occur when the immune system mistakenly attacks healthy cells in your body. Rheumatoid arthritis, one type of autoimmune disease, affects joints, leading to pain, inflammation, and swelling. Rheumatoid arthritis can affect your quality of life and ability to participate in everyday activities, but relief from symptoms — and even remission — may even be possible with the right action plan. Knowing your risk of the autoimmune disease rheumatoid arthritis, when to seek care, and treatment options can help you take control of this chronic disease.
In this article, we look at the autoimmune disease rheumatoid arthritis and discuss the disease’s causes, diagnosis process, stages, and management options. If you have rheumatoid arthritis, know that with comprehensive support and nutrition and lifestyle changes, your condition can improve.
What Is Rheumatoid Arthritis?
Rheumatoid arthritis (RA) is the most common autoimmune arthritis, affecting more than 1.3 million Americans, most of whom are women. Globally, RA affects .46% of the population. The onset of RA can occur at any age, but it usually appears between ages 30 and 50. (Source, Source)
As an autoimmune and inflammatory disease, RA affects the joints in your body. In RA, the lining of the joints becomes inflamed, damaging the joint tissue and causing chronic pain. Rheumatoid arthritis most commonly affects the joints in your hands, wrists, and knees, but other tissues may also be impacted. The disease typically attacks multiple joints simultaneously. (Source)
What Causes Rheumatoid Arthritis?
The exact cause of rheumatoid arthritis is unclear. Yet, scientists believe that a combination of genes and exposure to environmental factors initiates the onset of RA. Certain genes affect your chance of developing RA. Moreover, you are more likely to have RA if you have a family history of this disease. However, just because you have the genes associated with RA does not mean you will develop RA. (Source, Source)
Non-modifiable environmental factors — such as age and sex — influence your risk of rheumatoid arthritis. If you are genetically predisposed, your chance of developing RA increases as you age. Sex also affects your likelihood of RA — women are 2 to 3 times more likely to develop RA than men. Changes in sex hormones that occur with pregnancy can impact your RA; RA may improve during pregnancy only to flare afterward. (Source)
Modifiable environmental factors — such as smoking and diet — can trigger the onset of RA in genetically susceptible people. Cigarette smoking is the strongest environmental risk factor associated with RA. Obesity and a Western diet high in calories and low in fiber also increase risk. Quitting smoking and making healthy dietary changes may help prevent the onset of RA. (Source)
What Is the Difference Between Rheumatoid Arthritis and Osteoarthritis?
Osteoarthritis is the most common form of arthritis. It results from cartilage breakdown due to normal wear and tear on your body. The chance of developing osteoarthritis increases as you age, usually presenting after the age of 45. Symptoms include stiffness, swelling, tenderness, and joint pain that fluctuates in severity. You may also feel a crunching sensation or hear the sound of bone rubbing on bone due to the lack of cartilage. (Source, Source)
Although both involve inflammation and swelling of the joints, symptoms vary between RA and osteoarthritis. Rheumatoid arthritis causes more prolonged joint stiffness in the mornings and tends to affect joints on both sides of the body. While the effects of osteoarthritis are limited to joints, complications from RA can include damage to organs including the heart, kidneys, and skin. During RA flares you may experience flu-like symptoms such as fever, fatigue, and loss of appetite. (Source)
You may be unable to recognize the slight differences in symptoms between forms of arthritis. But your medical provider can diagnose your specific type of arthritis.
How Is Rheumatoid Arthritis Diagnosed?
To diagnose rheumatoid arthritis, your health care provider will review your medical history and conduct a thorough physical examination that may include X-rays, ultrasounds, and laboratory tests. Blood tests look for autoantibodies (antibodies that target your body’s own tissues) or markers of inflammation. You may be referred to a rheumatologist (a medical provider specializing in autoimmune disorders) to guide you through the diagnosis process.
Obtaining an autoimmune disease diagnosis can be difficult and may take time. You can prepare for your medical appointment by keeping a detailed record of symptoms to share with your provider. Treatment following an early diagnosis — within 6 months of the onset of symptoms — may effectively slow or stop disease progression, particularly in managing inflammation. (Source)
