D84.9: Immunodeficiency, unspecified
You have an immune deficiency.
The immune system protects the body from pathogens and foreign substances. The immune system can also destroy cells in the body that have pathologically changed. The body's immune system is made up of different types of immune cells. Some immune cells can destroy pathogens or foreign bodies themselves. Other immune cells produce certain antibodies.
Various conditions and drugs can cause an immune deficiency. An immune deficiency may also be congenital. In your case the precise cause is as yet unknown.
When someone has an immune deficiency, they are unable to properly combat various pathogens. Pathogens include bacteria, viruses and fungi, for example. The pathogens may then repeatedly cause infection. The infections can affect the respiratory tract, the gastrointestinal tract or the skin, for example. The infections may also be more severe and last longer than normal.
