Risk Factors
The accurate cause of rheumatoid arthritis is yet and remains unknown. It is one of several autoimmune diseases A person’s immune system is triggered to attack his or her own tissues. Over the past few years study conducted suggests that several factors may combine to cause rheumatoid arthritis (RA).
Sex, Age and family history
? The ratio of developing rheumatoid arthritisis more in women than men .
? Commonly between the ages of 40 and 60 rheumatoid arthritis occurs most However, it can also occur in older adults and in children (juvenile rheumatoid arthritis).
? You may have an greater risk of the disease if a member of your family has rheumatoid arthritis, Doctors don’t believe you can directly inherit rheumatoid arthritis. Instead, it’s believed that you can inherit a predisposition to rheumatoid arthritis.
? Smoking cigarettes increases the risk factor.
These include genetic factors, environmental factors and others.
Environmental Factors:-
Various researchers consider that something must occur to trigger rheumatoid arthritis (RA) in people whose genetic makeup makes them susceptible to the disease. This may be an infectious agent such as a virus or bacterium..It cannot be transmitted from person to person.
Genetic Factors:-
Certain genes that play a role in the immune system are associated with the likelihood of developing rheumatoid arthritis. However, many people suffering from this disease do not have these specific genes, and other people have these genes but never develop the disease. Other related factors. Some scientists have put forward their belief that certain hormonal factors may be involved in the development of rheumatoid arthritis (RA). These hormonal deficiencies/changes may trigger rheumatoid arthritis (RA) in a genetically susceptible person who has been exposed to an environmental trigger.
