What are the causes of low white blood count & low hemoglobin?

Updated April 17, 2017

There are a variety of conditions that can cause both low white blood cell count and low haemoglobin. These conditions are generally serious and require monitoring by a doctor.


Cancers, especially blood cancers like leukaemia, can cause significant damage to the blood. As a result, both your white blood count and haemoglobin count are lowered.


Some cases of anaemia are caused by a decrease in blood cell production in bone marrow. In these cases, both your haemoglobin and your white blood cell count will be low.


Chemotherapy treatments, while effective at treating cancer, can also damage blood cells and result in decreased haemoglobin and white blood cell count.

Autoimmune Diseases

Autoimmune diseases cause your immune system to attack your own body. Many can also result in damage to the blood, leading to a low haemoglobin and a low white blood cell count.

Nutritional Deficiencies

Nutritional deficiencies can also result in a low haemoglobin and low white blood cell count.
