01/08/2021 · Iron deficiency is widely considered to be the most common nutritional deficiency and one of the most common conditions identified, yet there is still uncertainty as to how to diagnose it. Iron deficiency occurs when iron losses or requirements exceed iron intake. Iron deficiency is particularly common in young children, premenopausal women, people with impaired iron absorption (eg, patients ...
