What is Iron Overload?
Excess iron accumulating in the body, most often from inherited haemochromatosis.

Genetic haemochromatosis.
Early symptoms for Iron Overload?
Fatigue and joint pain, easily attributed to other things.
Family testing for Iron Overload?
Recommended for first-degree relatives.
What is the single most useful thing to do?
Ask for testing if you have persistent fatigue with joint pain.
What is the most common mistake?
Iron supplements without a confirmed deficiency.
When should I see a doctor?
See a GP for persistent fatigue with joint pain, particularly if a relative has haemochromatosis. Seek urgent help for yellowing of the skin or eyes, abdominal swelling, palpitations or breathlessness, which can indicate liver or heart involvement. Never take iron supplements if you have iron overload.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
