Iron is a vital component of red blood cells, which transport oxygen around the body. Iron also helps our heart muscle cells produce energy.1 In people with symptomatic heart failure, the heart pumps less blood around the body and symptoms can be made worse by iron deficiency. Iron deficiency can reduce the amount of oxygen delivered to cells and reduce the ability of cells to produce energy.1 If you or a loved one have been diagnosed with heart failure, make sure that you know if your iron levels are low.
A lack of iron could be the cause of consistent tiredness or feeling run down regularly.
Shortness of breath4
You know your body best. Unexplained shortness of breath, especially when going up the stairs, could be as a result of low iron.
Light-headedness, or feeling faint, is not uncommon and could be caused by low iron levels.
