The causes of rheumatoid arthritis are yet unknown. At this point researchers suspect that some infectious agents, such as bacteria, viruses and fungi may be responsible, although there has been no proof. There is also some evidence of a genetic link because the condition ‘runs in families’. While the exact causative trigger isn’t known doctors do know that something ramps up the immune system and it begins to attack itself, promoting inflammation in the joints and other tissues in the body. (3)
There is some evidence that some of the triggers are environmental because scientists have reported that smoking tobacco will increase the risk of developing rheumatoid arthritis in young adults and adults. (4)
At this time doctors have labeled osteoarthritis as the condition of old age. This is because the condition forms in most people over the age of 60 when the wear and tear of life exceeds the ability of the cartilage and synovial fluid to prevent degeneration. Doctors do know that with increased stress this degeneration occurs more quickly and severely. For instance, an individual who is overweight will have greater pain, inflammation and severe disease process than someone who is of normal weight. Losing weight will also help to reduce the symptoms and decrease the advancement of the condition. (5)
While the exact causes of arthritis may not be identified, doctors have identified factors that can reduce the pain, inflammation, swelling and prevent further destruction of the joint. It is important to thoroughly research the type of arthritis you have been diagnosed with in order to work with your physician to find a treatment protocol which will be successful.
