Rheumatoid arthritis affects millions of people, and this chronic inflammatory disease can affect anyone. That’s why it’s important to know the following signs, symptoms, and facts about RA:
1. Rheumatoid Arthritis Isn’t Osteoarthritis
[ag_respa]Rheumatoid arthritis – commonly known as RA – is different from another form of the disorder called osteoarthritis. Nevertheless, like most people, you have probably heard others refer to both types of the disease as simply “arthritis.”
However, they are quite different, as RA is the result of an abnormal immune reaction, while osteoarthritis stems from erosion of the cartilage and bone and is primarily the result of aging, obesity, or overuse of various joints. For this reason, it is important to ask specific questions if you have been diagnosed with arthritis, as treatments for each type can be vastly different.
2. Muscle Atrophy and Loss of Appetite Are Common Symptoms
You may have known people in the past with rheumatoid arthritis who were extremely thin. This is because for multiple decades, those in the medical community were of the opinion that exercise would further damage the joints in RA patients and for this reason recommended a sedentary lifestyle. This caused individuals to suffer from muscle atrophy. In addition, a study completed by David Pisetsky, MD, a professor at Durham, North Carolina’s Duke University Medical Center, found that the chronic inflammation RA patients experience can cause extreme loss of appetite.
These two factors combined gave the disorder the nickname “wasting disease” in the 1960s. As you may have suspected, current opinions among immunologists and orthopedic specialists have changed over the years, and exercise is actually now part of the common treatment protocol for RA patients. Although during an extreme flareup exercise is not recommended, when a patient is enjoying a period of remission, doctors now state there is no evidence to suggest exercise would cause a flareup.
[ag_respb]Medicines are now available to curb the inflammation as well, making it easier to maintain a healthy active lifestyle. Additionally, nutritional supplements and special diets are often recommended to ensure that despite a lack of appetite, those suffering from RA still consume adequate nutrition.
3. Shared Epitope May Be the Cause
A genetic variant known as shared epitope is believed to be the cause of the disorder in certain individuals. There is also longstanding evidence that certain genotypes in the HLA class are linked to a higher risk of developing RA.
Researchers are working to determine if there is a way to isolate and alter such genes in predisposed patients before the disease manifests. If you or anyone you know suffers from rheumatoid arthritis, this research may eventually lead to some light at the end of the tunnel.
