With regard to rheumatic conditions, everyone is familiar with rheumatoid arthritis. However, rheumatism can occur in any organ. We should actually speak of autoimmune diseases, which are conditions that arise because our immune system accidentally attacks our own tissues and organs. In rheumatoid arthritis, the joints are attacked, but our immune system can also target the kidneys, skin, eyes, lungs, liver, intestines, vessels and heart. In general, these diseases are easy to treat. It is therefore almost always possible to take out life insurance.
