                                According to a 2021 study, iron deficiency without anemia (IDWA) is estimated to be at least twice as common as iron deficiency anemia. This condition, where the body's iron stores are low but hemoglobin levels remain normal, can still cause significant, debilitating symptoms and has been linked to long-term health complications.
