How to Increase your Iron

Intravenous iron and oral iron supplementation are two methods used to increase iron levels in individuals with iron deficiency or iron deficiency anemia. Here are some ways in which they differ and how intravenous iron can be beneficial:

  1. Absorption: Oral iron supplements are taken by mouth and must pass through the digestive system for absorption. However, the absorption of iron from oral supplements can be limited due to factors such as low stomach acid, poor absorption in the intestines, and interactions with other substances in the digestive tract. In contrast, intravenous iron is delivered directly into the bloodstream, bypassing the digestive system and ensuring immediate availability for the body to utilize.

  2. Efficiency: Intravenous iron can provide a more rapid and significant increase in iron levels compared to oral supplements. This is particularly beneficial for individuals with severe iron deficiency or those who are unable to tolerate oral iron due to gastrointestinal side effects or poor absorption.

  3. Compliance: Some people may struggle with consistent adherence to oral iron supplementation due to factors such as poor tolerance, difficulty swallowing pills, or gastrointestinal side effects like constipation or upset stomach. Intravenous iron bypasses these issues and ensures that the full dose of iron is received in a controlled manner.

  4. Medical Conditions: Intravenous iron may be preferred in certain medical conditions or situations where oral iron supplementation is insufficient or not recommended. This includes cases of severe iron deficiency anemia, chronic kidney disease, gastrointestinal disorders that affect iron absorption, malabsorption syndromes, or individuals who have undergone gastrointestinal surgeries that limit oral absorption.

  5. Monitoring: Intravenous iron administration typically requires medical supervision and monitoring to ensure safety and efficacy. Blood tests may be conducted before and after treatment to assess iron levels, and potential side effects or allergic reactions can be closely monitored.
