Low white blood cell count
A low white blood cell count usually means your body is not making enough white blood cells. It can increase your risk of getting infections.
What causes a low white blood cell count?
Common causes include:
- cancer treatment, like radiotherapy
- antipsychotic medicines
- medicine for an overactive thyroid
- some cancers, like leukaemia
- infections such as HIV or hepatitis
- autoimmune disorders, like rheumatoid arthritis
Agranulocytosis and neutropenia are conditions that cause a low white blood cell count.
Treating a low white blood cell count
A blood test can tell you if your white blood cell count is low.
Your treatment will depend on what's causing your condition and will often include antibiotics.
You may also need specific treatment:
- to boost your white blood cells
- if you've got an infection
Signs of an infection may include:
- a high temperature
- chills and shivering
- sore throat
- mouth sores that keep returning
- skin rashes
- flu-like symptoms
Occasionally, infections can lead to a life-threatening condition called sepsis.
