Feeling a bit low? Maybe it’s time to check your iron levels

Iron deficiency silently lurks, affecting many New Zealanders, yet often goes unnoticed until symptoms become severe. This condition, characterized by low iron levels results in insufficient red blood cell production (anaemia) and can have profound consequences on an individuals’ health and well-being.

To better understand this condition, we have to look at how it develops. Simply put, it can be thought of as either insufficient iron supply through reduced intake or absorption, or, increased demand through blood loss and iron consumption. It can be the first sign of a serious condition.

The signs and symptoms of iron deficiency anaemia extend well beyond mere fatigue and weakness and can include:

- Impaired cognitive and physical performance

- Compromised immune function

- Tongue pain

- Abnormalities in hair and nail growth

- Pale complexion

It can be easily detected through a community blood test (complete blood count and iron studies) arranged by your family doctor. Once detected however, a cause needs to be established.

Causes of iron deficiency with or without anaemia include:

- Reduced dietary intake

- Reduced absorption including coeliac disease and other inflammatory conditions of the small bowel

- Heavy menstrual blood loss

- Gastrointestinal blood loss including malignancy (cancer)

Whilst iron deficiency can be treated with dietary modification, oral supplementation or infusions, we strongly recommend investigations for all cases of iron deficiency in men and post-menopausal women. In pre-menopausal women, a thorough history, examination and discussion is required to determine if investigations are required.

The most common investigations you will require include gastroscopy (a flexible camera assessment of the stomach and first part of the small bowel) and colonoscopy (a flexible camera assessment of the large bowel or colon).
