Iron Overload Treatment: Phlebotomy

Overview

• The standard medical procedure for removing excess iron from the body is known as therapeutic phlebotomy, also referred to as venesection.
• This treatment is primarily used for conditions where iron accumulates to toxic levels, most notably hemochromatosis (both hereditary and secondary).

How the Procedure Works

• Blood Removal: Similar to a standard blood donation, a specific amount of blood (typically about 500 milliliters or one pint) is withdrawn from a vein, usually in the arm.
• Iron Depletion: Because the majority of the body's iron is stored within red blood cells (bound to hemoglobin), removing blood forces the body to use its excessive stored iron to produce new red blood cells, gradually lowering the total body iron burden.
• Frequency: The schedule depends on the severity of the iron overload. Initially, phlebotomies may be performed weekly or bi-weekly. Once iron levels normalize (maintenance phase), the frequency usually drops to every 2 to 4 months.

Nutritional and Dietary Considerations

• While phlebotomy is the primary medical intervention for removing accumulated iron, dietary management plays a supportive role:
• Limiting Red Meat: Reducing the intake of heme iron, which is absorbed much more efficiently by the body than plant-based (non-heme) iron.
• Avoiding Vitamin C Supplements: High doses of ascorbic acid enhance the intestinal absorption of non-heme iron and should generally be avoided unless specifically indicated.
• Caution with Alcohol: Alcohol consumption can significantly increase iron absorption and accelerate liver damage in individuals with iron overload.
• Minimizing Iron-Fortified Foods: Avoiding foods and cereals with added iron.
