Functions and role of iron in the human body

Since iron is not produced by the human body, and few people calculate its content in the diet, after a while, its deficiency begins to be felt. The lack of Fe causes anemia and is manifested by the following symptoms:

  • Birds before the eyes

  • Dry and pale skin

    / li

  • Difficulty

  • Nail polish

  • Dryness and hair loss.

    / li

Reasons for reducing iron concentration in the circulatory system:

  • Lack of food in the transition to a vegetarian diet, excessive consumption of fatty foods, not having in the composition of iron, or milk diets, when calcium does not give Fe assimilated.

  • Increased demand for various m microelements, including iron, during lactation and pregnancy, during a period of rapid growth in childhood and adolescence.

  • Diseases of the gastrointestinal tract leading to iron deficiency anemia, as they prevent the absorption of iron through the intestinal wall: gastritis, enterocolitis, enteritis, condition after resection of the stomach or small intestine, neoplasms.

  • Osteomyelitis, myocardial infarction, rheumatism, purulent, inflammatory, septic infections , a tumor with rapid growth dynamics, when Fe is actively absorbed from the plasma cr phagocytes.

  • hemosiderosis, when hemosiderin accumulates in the body tissues, which leads to a decrease in the level of iron in the blood.

  • li

    Chronic renal failure leading to erythropoietin deficiency in the kidney.

  • li

    Nephrotic syndrome in which iron is actively excreted in the urine.

  • li

    Prolonged bleeding: menstrual, hemorrhoidal, nasal, etc. D.

  • Active hematopoiesis with severe use of iron.

  • Malignant and benign tumors, cirrhosis, ra to the liver

  • Obstructive jaundice resulting from congestion of bile (cholestasis).

  • Vitamin C deficiency that promotes iron absorption. How to increase the level of iron in the blood?

    It is difficult to increase the level of Fe, not knowing the reasons for its decrease. Even a diet rich in microelements can not affect this process if the digestion of iron is disturbed. In order not only to ensure the transit of iron through the gastrointestinal tract, but to fully influence the cause of its decrease, it is necessary to follow the recommendations of the doctor, undergo a full examination.

    Products for saturation of the diet with iron:

    • Meat: rabbit, lamb, veal, beef, turkey, goose. Pork fat does not have Fe in its composition.

    • The liver of animals, which is the organ of hematopoiesis. It is important to remember the possible high level of toxins, and not include offal in the diet too often.

    • Eggs contain little iron, but they are rich in phospholipids, vitamins B 1, B 12,

    • Buckwheat as the best product against iron deficiency anemia.

    • The use of vegetables and fruits to replenish the stores of ascorbic acid, which helps to absorb iron through the walls of the intestine. The best for this fit citrus (lemon, orange) and sauerkraut. You can eat vegetables and fruits rich in Fe: apples, peas, beans, prunes, spinach, but the microelements penetrate the digestive tract in the smallest amount.

    Foods rich in calcium ( cottage cheese, milk, cheese), interfere with the full absorption of Fe, so they are used separately from food rich in this microelement.

    The organism will not allow excess iron, even if it is used excessively, because it has mechanisms for the regulation of metabolism microelements.
