D89.8: Other specified disorders involving the immune mechanism, not elsewhere classified
Your immune system has a disorder.
There are various kinds of defense cells (immune cells) in the body. Specific immune cells produce antibodies in the blood. The antibodies cling to pathogens and foreign substances in the blood, for example. This allows the antibodies to make the pathogens and foreign substances visible to the immune system. The immune system helps the body to fight and eliminate diseases and foreign substances.
When the immune system has a disorder, it may not create the right antibodies, for example. The immune system may also produce too many or the wrong antibodies, or certain defense cells may not be produced properly.
When there is a disorder in the immune system, the body finds it harder to protect against pathogens. So you become ill more easily. Your immune system may also attack your own body or inflammations can occur around the body. Then you can get fever, diarrhea or inflammations of the airways, for example. If the disorder is congenital, it can delay physical and mental development.
