Neutropenia (say "noo-truh-PEE-nee-uh") means that your blood has too few neutrophils. These are white blood cells that help protect the body from infection. They do this by killing bacteria.
Neutropenia can be caused by some types of infection. It also can be caused by immune system conditions such as HIV or lupus, a lack of vitamin B12 or folic acid, or an enlarged spleen. Some medicines can cause it too. It is most often caused by treatments for certain health problems, such as chemotherapy and radiation treatment for cancer.
Mild neutropenia usually causes no symptoms. But when it's severe, it increases the risk of infection of your skin and organs. That's because your body can't fight off germs as well as it should.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
