Iron Deficiency and What Everyone Should Know About Testing and Treatment

Over the past 25 years, one of the most common and preventable medical oversights I’ve encountered is the failure to diagnose and properly manage iron deficiency anemia. This issue disproportionately affects women, especially those of childbearing age, and it’s frustratingly simple to address with the right tests and treatment plan.

Here’s what you need to know to protect yourself from iron deficiency anemia, ensure early detection, and maintain optimal iron levels for long-term health.

Why Iron Matters

Iron plays a crucial role in your body, helping produce hemoglobin, the protein in red blood cells that carries oxygen throughout your body. A lack of iron can lead to iron deficiency anemia, causing fatigue, weakness, and a range of other health problems.

Women, particularly those who menstruate, are at a higher risk of iron deficiency due to monthly blood loss. Athletes, especially young women, are also at increased risk because physical activity raises the body’s iron requirements.

The Difference Between Iron Deficiency and Anemia

Iron deficiency is a state where your body’s iron reserves are low but may not yet impact your red blood cell production. Anemia, however, occurs when iron levels drop so low that your body can no longer produce enough healthy red blood cells.

Anemia is commonly diagnosed using a Complete Blood Count (CBC) test, which measures red blood cells, hemoglobin, and hematocrit levels. While the CBC is an essential tool, it only identifies anemia after significant iron depletion has occurred.

To catch iron deficiency before it progresses to anemia, a ferritin test is critical. Ferritin measures your body’s iron storage levels and is the most reliable indicator of early iron deficiency.

How to Advocate for the Right Tests

Annual CBC Test:
Every teenage girl, premenopausal woman, and athlete should have a CBC test annually. If your doctor doesn’t offer it during a physical, request it—especially during sports physicals.

Ferritin Test:
Ferritin is not part of a standard CBC, so you must specifically ask for it. A ferritin level below 30 suggests low iron storage, even if your CBC appears normal. Aim for a ferritin level of at least 75 for optimal health.

Don’t Ignore Symptoms:
Symptoms like fatigue, weakness, and difficulty concentrating can occur even with mildly low ferritin levels. Advocate for thorough testing if you experience these symptoms.

Treating Iron Deficiency

Choosing the Right Iron Supplement:
Iron supplements are essential for treating iron deficiency but can cause digestive upset. The following options may help:

• Iron Bisglycinate: A gentle, well-absorbed form of iron that minimizes gastrointestinal side effects.
  Iron Patches: These deliver iron through the skin, bypassing the digestive system and offering a great alternative for those with sensitive stomachs.
  Dosage:
  For most people, a daily dose of 25 mg of iron bisglycinate, taken twice a day, is effective. Follow your doctor’s recommendations for your specific needs.

Consistency Is Key:

• Restoring your iron levels takes time. On average, ferritin increases by only 3–7 points per month with consistent supplementation. Depending on your starting levels, it could take a year or more to reach optimal ferritin levels.

Monitor Your Progress:

• Recheck your ferritin levels annually to ensure your treatment is effective and to prevent future deficiencies.

Prevention Is Better Than Cure

Iron deficiency is preventable with routine testing and proactive treatment. Early detection through ferritin testing allows you to address deficiencies before they become anemia, sparing you from fatigue and other debilitating symptoms.

By advocating for annual CBC and ferritin tests and choosing the right supplementation strategy, you can maintain healthy iron levels and avoid the pitfalls of iron deficiency anemia.
