Research has demonstrated that many individuals with Crohnâs ileitis share a genetic mutation that may play a significant role in disease development. A hypersensitive immuno-response to a pathogenic presence, such as bacteria, within the gastrointestinal tract is also suspected of contributing to the disease's onset.
Secondary osteoarthritis occurs less frequently than primary (also known as idiopathic) osteoarthritis. Primary osteoarthritis means that there is no known cause for the joint breakdown.
Osteoarthritis (OA) is a form of degenerative joint pain caused by wear and tear on your joints. As you age, the cartilage that cushions your joints starts to wear down, causing the bones to rub together. The bone-on-bone action leads to inflammation of the joints. Osteoarthritis most commonly affects the joints in your arms and legs, including your fingers, wrists, knees, ankles, and hips. The lower back is also a common source of OA pain. Let your doctor know if youâre suffering from the early symptoms of osteoarthritis.
