Iron deficiency is one of the most common nutritional deficiencies worldwide. It occurs when the body does not have enough iron to meet its needs and can lead to iron-deficiency anaemia if left untreated. Common causes include blood loss, particularly during menstruation, and insufficient dietary intake.
Less commonly, iron deficiency may be linked to a digestive disorder that affects iron absorption or to conditions that interfere with the body’s ability to use iron effectively.
Those most at risk of iron deficiency are:
Children aged 6 months to 3 years (often between 6 and 18 months) due to high iron requirements linked to their growth
Pregnant women and iron deficiency: this is linked to an increase in blood volume and the significant demands of the foetus, which draws on its mother’s reserves
Women with very heavy or prolonged periods
People following a vegetarian or vegan diet
