Rheumatic diseases are the result of inflammation affecting the body's immune system by breaking down connective tissues and related structures. These diseases affect tendons, ligaments, bones and muscles, but can also impact organs, ultimately causing a loss of function in the body.
Rheumatic diseases are caused by genes, environmental factors, or a combination of both. The disease, in addition to the most common symptoms of pain, stiffness and muscle weakness, may also produce fatigue, eye inflammation, eye infections, rashes, sores and difficulty breathing.
