Diagnosing iron deficiency early is critical

Without proper intervention, iron deficiency anemia can become dire and even life-threatening, leading to the following potential complications:8-11
  • Heart and lung conditions
  • Worsening chronic conditions
  • Reduction in the effectiveness of medications
  • Organ damage
  • Maternal morbidity during pregnancy40
Iron deficiency anemia in pregnant women can also impact fetuses and newborns.18, 24, 36, 37 They may:
  • Develop iron deficiency in their first year of life
  • Be small for their gestational age
  • Face admission to the neonatal care unit
  • Have a low birth weight
  • Face increased risk of preterm birth
  • Face higher rates of neonatal morbidity and mortality
By knowing what to test for and acting quickly, you can prevent the progression of iron deficiency to iron deficiency anemia.8-10

Iron deficiency impacts more patients than you might realize.

In the United States, approximately 10 million people have iron deficiency and approximately 5 million have iron deficiency anemia.16

You may be seeing patients every day who are at risk for iron deficiency and iron deficiency anemia

Many women may experience iron deficiency or iron deficiency anemia in their lifetime18

Women are at risk of ID and IDA because they are likely to experience at least one, but likely several, conditions that lead to iron deficiency, including the following:
  • Heavy menstrual bleeding (menorrhagia)
  • Pregnancy
  • Uterine fibroids
  • Childbirth
  • Menopause
Worldwide, up to

30%

of women of childbearing age may have IDA.26

37%

Patients with other underlying conditions are also at risk

Prevalence of iron deficiency and iron deficiency anemia is also high among patients with inflammatory conditions, such as inflammatory bowel disease (IBD) and chronic kidney disease (CKD).21,22,23†

Other conditions and factors associated with ID and IDA include:24
  • Malabsorption syndrome
  • Nutritional deficits
  • Restrictive diets
  • Heart failure
  • Surgery
  • Cancer

36-90%

of patients with IBD (eg, Crohn's, UC) have ID.21

hips with pain

36-76%

of patients with IBD (eg, Crohn's, UC) have IDA.22

intestine with pain

20-65%

of patients with CKD have ID.23

kidneys

11-27%

of patients with CKD have anemia.23

  • Although there is overlap between ID and IDA, some markers are sensitive to assessing ID (ferritin) and some markers are indicators of IDA (hemoglobin).
Identifying ID/IDA
Learn how to spot the signs and symptoms of ID and IDA so you can treat patients effectively.
Downsides of Oral Iron Salts
Learn why iron supplements can make your patients feel worse instead of better.
