Causes, Symptoms & Cures For Rheumatoid Arthritis
Genes And Environmental Factors

As discussed, an individual's genes may not cause rheumatoid arthritis, but it can make them more susceptible to developing it. Environmental factors such as a highly inflammatory diet may activate or trigger the disease. Certain viruses and bacteria may also trigger the disease as they weaken the immune system, making it easier for other conditions to develop. Individuals who have been diagnosed with other autoimmune conditions such as lupus, Crohn's disease, and ulcerative colitis are at an increased risk of developing rheumatoid arthritis, as their immune system is already compromised.
