Ferritin is a protein that stores iron and is an acute-phase protein characteristic of inflammation and infection. Each μg/l of this protein is responsible for binding 8 mg of iron. When should one pay attention to its excess or deficiency? More about this can be read in the following article.
Elevated ferritin levels – etiologies, diagnostic approaches, and clinical implications of excessive iron storage
A condition in which serum ferritin concentrations exceed reference ranges—specifically, values above 200 micrograms per liter in women and 400 micrograms per liter in men—may indicate a spectrum of metabolic disturbances, inflammatory states, or hereditary disorders. Etiologies of hyperferritinemia encompass excessive iron supplementation, acute-phase responses during bacterial or viral infections (where levels may reach up to 800 µg/L), and chronic conditions such as hyperthyroidism, chronic kidney disease, or hepatic cirrhosis (including alcohol-induced liver damage, where values exceeding 1000 µg/L may accompany alcohol cessation). Additionally, non-alcoholic fatty liver disease, primary (hereditary) or secondary hemochromatosis, functional iron deficiency in chronic diseases (e.g., during inflammatory exacerbations), and certain pharmacotherapies necessitate differential diagnosis. The diagnosis of hemochromatosis relies on concurrent elevation of ferritin and transferrin saturation, suggesting a genetic mutation in the iron-regulatory membrane protein. Rare entities include hemosiderosis (deposition of hemosiderin in the liver and lungs, e.g., post-frequent transfusions) and hemophagocytic lymphohistiocytosis—a hyperinflammatory autoimmune disorder characterized by excessive activation of T lymphocytes and NK cells, leading to chronic inflammation and tissue damage. This syndrome may be genetic, congenital, or acquired, as seen in Epstein-Barr virus infections, autoimmune diseases (Crohn’s disease, ulcerative colitis), or hematologic malignancies (lymphomas).
Insufficient ferritin levels in the body: Symptoms, causes, and implications of reduced concentrations
A condition characterized by inadequate ferritin levels is identified when concentrations fall below 10 micrograms per liter in women and below 20 µg/l in men. This iron-storage protein deficiency typically serves as a marker of disrupted iron metabolism, frequently culminating in iron-deficiency anemia. The decline in ferritin levels also functions as an early warning indicator, signaling the imminent onset of iron-deficiency anemia within a short timeframe. Consequently, such findings necessitate a thorough diagnostic evaluation of hematopoiesis and iron homeostasis to determine underlying causes and appropriate interventions.
How do you raise your ferritin levels?
Since ferritin is a protein, special attention should be paid to the quality and quantity of calories and macronutrients in the daily diet of a person. A restrictive low-calorie diet leads to the conversion of carbohydrates, fats and proteins into energy instead of protein for regeneration and body rebuilding. Red blood cells are also replaced with new ones within 120 days, so to improve the health outcomes of this diet and the characteristics of the iron economy, including an increase in the level of iron content, the need for time to reduce the amount of iron in the diet. Therefore, it is necessary to pay attention to the full-value of protein in the body by using the low-carbohydrate products of the body, the fat in the stomach and the fat of the intestine, the nutritional intake of the digestive tract, but at the same time, the nutrients and nutrients of the liver, including the nutrient sources of the food, and in the case of pigs, eggs, legumes, grapefruit, leguminous vegetables, grains, and legumes (suchlorin and wheat
