From the Guidelines
Intravenous iron therapy is the most appropriate treatment for iron deficiency anemia in a patient with a colostomy and severe anemia, as it bypasses the gastrointestinal tract and provides rapid correction of anemia. The patient's hemoglobin level of 8.6 indicates severe anemia, which requires prompt treatment. According to the most recent and highest quality study 1, intravenous iron therapy is recommended for individuals with inflammatory bowel disease, iron-deficiency anemia, and active inflammation with compromised absorption. Although the patient has a colostomy, the principle of bypassing the gastrointestinal tract to ensure adequate iron absorption still applies. Some key points to consider in the treatment of iron deficiency anemia in patients with colostomy include:
- Intravenous iron formulations such as iron sucrose, ferric carboxymaltose, or iron dextran are recommended, with dosing based on the patient's weight and hemoglobin level 1.
- Ferric carboxymaltose might be administered as 750-1000 mg per infusion, with a second dose given after 7 days if needed.
- Blood transfusions may be necessary if the patient is hemodynamically unstable or has a hemoglobin below 7 g/dL.
- Regular monitoring of hemoglobin, ferritin, and transferrin saturation is essential to assess treatment response and guide maintenance therapy 1. It is also important to identify and address the underlying cause of iron deficiency, which may involve evaluating for ongoing blood loss from the remaining colon or other sources.

From the Research
Treatment Options for Iron Deficiency Anemia
- Ferrous sulfate is a commonly prescribed oral iron supplement for treating iron deficiency anemia, as stated in 2.
- However, oral iron supplementation can cause gastrointestinal side effects, reducing compliance, as mentioned in 2 and 3.
- In cases where oral iron supplementation is contraindicated or not tolerated, intravenous iron therapy can be considered, as discussed in 4 and 5.
Considerations for Patients with Colostomy
- There is no specific evidence provided regarding the treatment of iron deficiency anemia in patients with colostomy.
- However, the general principles of treating iron deficiency anemia can be applied, taking into account the patient's individual needs and medical history.
Severe Anemia (Hgb 8.6)
- Severe anemia requires prompt treatment to improve symptoms and quality of life, as mentioned in 5.
- Intravenous iron supplementation can rapidly correct iron deficiency anemia, as stated in 4 and 5.
- Oral iron supplementation, such as ferrous sulfate, can also be effective, but may be limited by gastrointestinal side effects, as discussed in 2 and 3.
Comparison of Treatment Options
- A study comparing oral high-dose sucrosomial iron with intravenous iron in patients with sideropenic anemia found that both treatments were effective, but intravenous iron was quicker, as reported in 6.
- Another study found that ferrous sulfate was more effective than iron polysaccharide complex in increasing hemoglobin concentration in young children with nutritional iron-deficiency anemia, as stated in 3.
