This condition is caused by either internal or external bleeding, destruction of red blood cells or decreased production of red blood cells. Diseases and other causes such as cancer, immune disease, chemical or drug toxicity, parasites, poor nutrition and others can cause one of these conditions to develop.
Signs of this condition include pale or white gums and white of the eyes. Weakness and lethargy are also common. A complete blood count is needed to assess the condition.
