Iron deficiency, common across all age groups, often leads to anemia or non-anemia symptoms like fatigue. While oral iron supplements are typically used to treat iron deficiency, they can cause gastrointestinal issues and may not be effective for all deficiencies.
Intravenous (IV) nutrition therapy directly delivers essential nutrients like vitamins, minerals, and amino acids into the bloodstream, offering fast and optimized nutrient delivery. Iron perfusion is a prevalent form of IV therapy, crucial for producing hemoglobin and ATP and regulating vital physiological processes. In addition, newer iron preparations, including intravenous iron administration, are more stable and have lower risks of side effects, with more significant therapeutic benefits over a shorter period. 1
What is Iron Malabsorption?
Iron malabsorption is a condition in which the intestines are unable to properly absorb iron from the diet. If left untreated, it can lead to iron deficiency anemia.
Causes of Iron Malabsorption
A number of factors can prevent the body from properly absorbing iron from food, leading to iron malabsorption. The 5 main causes of iron malabsorption are:
Gastrointestinal Disorders: Conditions such as celiac disease, Crohn's disease, and ulcerative colitis can significantly impair iron absorption. These gastrointestinal disorders often lead to gastrointestinal distress, which can further complicate iron metabolism and contribute to low red blood cell count. Surgical interventions on the intestines can also disrupt normal absorption processes, leading to malabsorption syndrome.
Medications: Certain medications, particularly proton pump inhibitors (PPIs), can cause hypochlorhydria, or low stomach acid production. This reduction in acidity can hinder the absorption of dietary iron and lead to iron deficiencies. Additionally, medications like metformin may also affect iron absorption.
Genetic Factors: Genetic predispositions, such as hereditary hemochromatosis, can lead to abnormal iron metabolism and systemic iron homeostasis. Conditions like thalassemia can also affect how the body utilizes iron, potentially leading to iron-deficient erythropoiesis.
Dietary Factors: A diet low in vitamin C can inhibit iron absorption, as vitamin C enhances the bioavailability of non-heme iron. High levels of phytates, found in certain grains and legumes, can bind iron and reduce its absorption. Additionally, excessive calcium intake can interfere with iron absorption. Individuals with pagophagia, or a craving for ice, may also experience dietary iron deficiencies, which can exacerbate malabsorption issues.
Blood Loss: Chronic blood loss, whether from heavy menstruation, rectal bleeding, or gastrointestinal bleeding due to ulcers or polyps, can lead to significant iron depletion. This loss can create a cycle where low iron levels further hinder the body's ability to produce adequate red blood cells.
Symptoms of Iron Malabsorption
The symptoms of iron malabsorption are similar to those of iron deficiency anemia, which include:
Fatigue and weakness
Pale skin
Shortness of breath
Rapid heartbeat
Headaches
Dizziness
Brittle nails
Unusual cravings for non-food items (pica)
What is Iron-deficiency Anemia?
Iron deficiency anemia is a condition caused by insufficient iron, leading to a reduced production of healthy red blood cells and hemoglobin. Symptoms include fatigue, weakness, pale skin, shortness of breath, and dizziness. Common causes include blood loss (from heavy menstruation or gastrointestinal bleeding), inadequate dietary intake, malabsorption issues, and increased iron demands during pregnancy. Treatment typically involves dietary changes, iron supplementation, and addressing underlying causes of the deficiency.
When is an Iron IV Therapy Suitable for Patients?
Iron IV therapy is suitable for patients in various clinical scenarios where oral iron supplementation may not be effective or feasible. 5 Key situations where intravenous iron therapy is particularly beneficial include:
Intolerance or non-compliance with oral iron: Patients who experience gastrointestinal side effects from oral iron may find IV therapy a viable alternative.
Severe iron deficiency anemia (IDA): IV iron therapy is indicated for patients with severe IDA, allowing for rapid correction of iron levels, which is crucial in acute situations.
Gastrointestinal disorders: Patients with conditions that impair iron absorption, such as celiac disease or Crohn's disease, may benefit from IV iron therapy due to malabsorption syndromes.
Functional iron deficiency: In cases where patients have adequate iron stores but cannot utilize iron effectively, IV iron therapy can help restore iron availability for erythropoiesis.
Rapid iron repletion needs: Situations requiring immediate iron replenishment, such as autologous blood donation before surgery or for patients with heavy menstrual bleeding, are ideal for IV iron therapy.
Before starting iron IV therapy, it's important to measure iron levels in the blood. While there's no universally agreed-upon normal range for iron levels, ferritin, a protein that reflects the body's iron stores, is a reliable indicator. If a patient's ferritin level is below 15 nanograms per milliliter (ng/ml), it suggests that their iron reserves are depleted. Patients should be advised to undergo a blood test to measure ferritin levels and discuss the results before proceeding with treatment.
What are the Benefits of IV Iron Infusion?
Iron IV infusion offers several benefits, particularly for individuals with iron deficiency anemia or those unable to absorb iron effectively through oral supplements. Here are the key benefits:
Rapid Iron Replenishment: Quickly increases iron levels, improving symptoms like fatigue and weakness within days to weeks.
Bypasses Gastrointestinal Issues: Reduces the risk of gastrointestinal distress for patients intolerant to oral iron supplements.
Immediate Symptom Relief: Patients often experience increased energy and improved concentration shortly after the infusion.
Convenience: Administered in a clinical setting, often in a single session, making it more convenient than daily oral supplements.
Effective for Various Conditions: Particularly beneficial for individuals with chronic kidney disease, inflammatory bowel disease, or those needing rapid iron replenishment.

Final Thoughts
Iron deficiency can be a common condition, stemming from various issues ranging from cardiac disease to an iron-poor diet. Therefore, recommending novel iron supplementation methods such as IV therapy for your patients can improve their condition and quality of life.
