Copper deficiency is uncommon, but is sometimes found in combination with iron deficiency, especially with iron deficiency anemia.
Causes and Development
As
zinc supplementaion is becoming more popular, the effect of reduced
copper absorption seen with increased zinc consumption will probably make deficiencies of copper become more common.
Signs and Symptoms
Fatigue, paleness, skin sores,
edema, slowed growth, hair loss,
anorexia,
diarrhea and
dermatitis can be symptoms of
copper insufficiency.
The reduced
red blood cell function and shortened red cell life span found with copper deficiency can influence energy levels and cause weakness and labored respiration from decreased oxygen delivery. Low copper levels may also affect
collagen formation and thus tissue health and healing. Reduced
thyroid function,
cardiovascular disease, increased
cholesterol,
uric acid and blood pressure, impaired
glucose tolerance,
thrombosis, oxidative damage, skeletal defects related to bone demineralization and poor nerve conductivity (copper deficiency adversely affects electrocardiograms) - including irregular heart rhythms - can all result from copper depletion.
Copper deficiency results in several abnormalities of the immune system, such as a reduced cellular immune response, reduced activity of
white blood cells and, possibly, reduced
thymus hormone production, all of which may contribute to an increased infection rate. Infants fed an all-dairy (cow's milk) diet without copper supplements may develop copper deficiency.
