While in degenerative diseases an imbalance between the load and the resilience of a joint exists (easily conceivable in overweight), in soft tissue rheumatism is still unclear what exactly is the trigger for the disease. Currently, it is believed that genetic influences play a role - just as in the inflammatory-rheumatic diseases, in which the immune system reacts with the formation of antibodies to body parts.
Rheumatoid arthritis and metabolic diseases
In rheumatoid arthritis and collagenosis / vasculitis - these are the diseases of connective tissue and blood vessels - certain docking sites (HLA receptors) that are targeted to the immune system are falsely formed on the body's cells. Thus, the immune system recognizes the body's own cells (of joints, skin, vessels or digestive tract) as an enemy.
In the case of metabolic diseases, however, too much uric acid (as in gout) or too little calcium and vitamin D (as in osteoporosis) lead to a change in the bones or joints. Back or neck pain can also be caused by a bad load (incorrect sitting, unilateral load) or tension in the muscles - lumbago or lumbago are the consequences.
How do rheumatic diseases express themselves?
Pain - be it in joints or in muscles, tendons and ligaments - is the main symptom of rheumatism. The pain varies depending on the disease and sufferer and usually leads to a restriction of movement. In addition, complaints to other organs are possible - especially in connective tissue diseases. For example, dry eyes can be found in Sjögren syndrome, reddened areas of the skin in lupus disease and a diminishing elasticity of the skin, tongue and esophagus in scleroderma.
