Iron: a common, fixable cause of tiredness
Low iron is especially common in women, endurance athletes and people who eat little red meat.
Iron studies show both what you store and what you carry. Your doctor will look for the cause of any low result, not just treat the number.
What iron does
Iron helps red blood cells carry oxygen. When stores run low, you can feel tired, breathless on exertion or slow to recover.
Who is at risk
People with heavy periods, endurance athletes, vegetarians and vegans, and people with some gut conditions are more likely to run low.
What the tests show
Ferritin reflects your stores. Other parts of iron studies show how much is circulating. Together they give a clearer picture.
Finding the cause
A low result is a starting point. Your doctor will look at why, because the right fix depends on the cause.
