Iron plays a vital role in producing red blood cells, which are carriers of oxygen throughout our bodies. Low iron levels can lead to iron deficiency anaemia, often recognised by feelings of fatigue, low energy levels, and a paler than usual complexion.
There are, however, less common indicators that could signal anaemia. Our mouths may reveal three signs indicative of low iron, according to NHS guidance.
These are food tasting strange, recurring mouth ulcers, and a sore tongue. If you think you may have an iron deficiency, it is important to consult your GP, who is likely to refer you for a straightforward blood test to check if you’re anaemic or not.
NHS guidance adds: “The GP will ask you about your lifestyle and medical history. If the reason for the anaemia is not clear, they might order some tests to find out what might be causing the symptoms. They might also refer you to a specialist for further checks.”
If the blood test shows your red blood cell count is low, you’ll likely be prescribed iron tablets to replace the iron that’s missing from your body. In cases where oral supplements do not work or are poorly tolerated, or where iron stores need to be built up quickly, intravenous (IV) iron injections may be given.
