Iron study – frequently asked questions

In this article we are going to try to solve the most frequent doubts about iron, its study and what problems both the excess and the lack of iron can bring us.

What foods have the highest iron content?

Basically those foods that contain blood such as meats (undercooked), liver, kidneys, spinach, chard, lentils, beans, chickpeas and some drinks such as red wine. Milk, eggs and potatoes have low iron content

What daily iron needs do we have?

An adult in normal conditions needs 1 mg / day, with a usual diet 10 mg / day are ingested, absorbing 10%, but in case of need it can be absorbed up to 30%. Women of childbearing age need an extra daily intake of 1.5 to 2 mg / day for menstrual losses. Newborns have the iron they need for the first 4 months of life and breast milk ensures their needs until the first 6 months of life.

When is there most risk of developing iron deficiency anemia in young children?

Up to 4 months it is protected by breast milk, from 4 to 12 months of life, iron needs are greater. For this reason, at this age it is decisive for the development of iron deficiency anemia.

In women of childbearing age, does the contraceptive method influence more easily present iron deficiency anemia?

Those women who have an intrauterine device (IUD) have iron deficiency anemia more easily than those who use oral contraceptives since they save blood.

Where is iron absorbed?

Its place of absorption is the duodenum and proximal jejunum, favoring its absorption as ferrous sulfate and the presence of acidic substances such as vitamin C (orange or lemon juice): The intake of alkalines such as antacids, milk, makes absorption difficult.

What is ferritin?

It is the iron storage protein, values ​​of 10-20 (g / L are highly suggestive of iron deficiency anemia; values ​​less than 10 g / L in the absence of hypothyroidism and vitamin C deficiency are diagnostic of iron deficiency anemia.

What is the treatment for iron deficiency anemia?

A daily dose of the preparation should provide 100 to 200 mg of elemental iron; therefore, depending on the preparation, as many tablets will be taken per day as necessary to guarantee said contribution. For example, a 200 mg ferrous sulfate tablet contains 60 mg of elemental iron, which means that it will be necessary to take 3 to 4 tablets a day before meals.

How do you know in the laboratory if the treatment is working?

The response to treatment is correct when hemoglobin increases 1 g per week, after reaching the normal level of hemoglobin, treatment must be continued for at least 3 months to fill the deposits. 15 days after treatment, another iron study should be done.

With a low iron value, can you say that I have iron deficiency anemia?

NOT. There are many other situations that occur with low iron, therefore it is necessary to study all the parameters to confirm iron deficiency anemia or at least sideremia , ferritin and free erythrocyte protoporphyrin (PEL).

What other alternatives are there if there is digestive intolerance or a defect in the absorption of ferrous salt?

If oral treatment does not work, parenteral, intramuscular iron can be taken in the form of sorbitol or dextran as determined by the doctor. At present, the natural iron protein is available that improves tolerance and absorption, although it has a high cost as it is a long-term treatment.

How is the blood count for iron deficiency anemia?

Microcytic anemia and hypochromia (all the parameters of the red series are lowered; RDW (= RDW) is usually increased (anisocytosis); low reticulocytes; low sideremia; very low ferritin; TIBC and transferrin increased;% saturation (IST) less than 16 % and elevated PEL).

When is iron deficiency anemia suspected in pregnancy?

In pregnancy there is a hemodilution, the total blood volume and plasma increase more than the mass of red blood cells. It begins at 8 weeks of pregnancy and complete development at 16-22 weeks, the hemoglobin averages 11 g / dL, the average hematocrit value is 33%, with normal erythrocyte indices. If hemoglobin is less than 10 g / dL or there are hypochromic microcytic indices, iron deficiency anemia, which frequently appears in pregnancy, must be ruled out.
