Iron deficiency anemia (IDA) is the most common form of anemia, characterized by a lack of iron in the body, which leads to a decrease in hemoglobin production and, accordingly, a decrease in the number of red blood cells. This condition can be caused by various factors, including insufficient iron intake with food, increased needs of the body (for example, during pregnancy or growth) and iron loss (during blood loss, gastrointestinal diseases, etc.). Symptoms of anemia can vary from mild fatigue and weakness to severe pallor of the skin, tachycardia and shortness of breath during physical exertion.
History of the disease and interesting historical facts
Iron deficiency anemia has been known to mankind for many centuries. The first mentions of this pathology can be found in the medical manuscripts of Ancient Egypt. And in the 4th century BC, Hippocrates described symptoms similar to modern manifestations of anemia and associated them with a lack of blood. In the 19th century, scientists began to identify the connection between anemia and iron deficiency, which became the basis for further research. In 1932, it was found that the addition of iron-containing drugs helps improve the condition of patients with iron deficiency anemia. However, despite the achievements of medicine, this disease remains a pressing health problem and requires constant attention.
Epidemiology
According to the World Health Organization, iron deficiency anemia affects more than 1.6 billion people worldwide, representing approximately 24.8% of the population. Women of reproductive age and children are most susceptible to the disease. Approximately 30% of pregnant women have iron deficiency anemia, which is associated with an increased need for iron. Studies also show high rates of the disease in developing countries, where iron deficiency is one of the most common nutritional deficiencies.
Genetic predisposition to this disease
Research suggests that genetic factors may play a role in predisposition to iron deficiency anemia. Mutations in genes involved in iron metabolism, such as HFE (hyperpheriasis), may contribute to increased iron accumulation in the body, but the relationship between these genes and iron deficiency anemia requires further research. At the same time, a family history of gastrointestinal diseases may increase the risk of developing anemia due to impaired iron absorption.
Risk factors for the development of this disease
Risk factors that contribute to the development of iron deficiency anemia are varied and include:
- Lack of iron in the diet (vegetarianism, lack of iron-rich foods).
- Increased iron requirements (pregnancy, growth in childhood and adolescence).
- Blood loss (external and internal, including frequent menstruation in women).
- Diseases of the gastrointestinal tract (celiac disease, ulcers, inflammatory processes).
- Chronic diseases (pneumonia, cancer, cardiovascular diseases).
Diagnosis of this disease
Diagnosis of iron deficiency anemia includes several stages and methods:
- Main symptoms: fatigue, weakness, dizziness, pallor, shortness of breath.
- Laboratory tests: complete blood count and determination of ferritin levels, serum iron and transferrin levels.
- Radiological tests: Sometimes used to detect diseases that may cause blood loss.
- Other diagnostic tests: bone marrow biopsy in rare cases.
- Differential diagnosis: exclude other types of anemia (eg, vitamin B12 deficiency anemia, anemia of chronic disease).
Treatment
Treatment of iron deficiency anemia includes both general measures and specific therapy. General treatment involves:
- Dietary adjustments with increased consumption of iron-rich foods (red meat, liver, beans, green leafy vegetables).
- Pharmacological treatment using iron-containing drugs (both oral and injectable).
- Surgical treatment in cases where anemia is caused by tumors or other serious organs.
- Other treatments include vitamin therapy (if necessary, adjusting vitamin C levels to improve iron absorption).
List of medications used to treat this disease
Among the medications used to treat iron deficiency anemia are:
- Solcoseryl - to restore metabolism and improve iron absorption.
- Ferrum Lek is an injectable iron preparation.
- Totem is an oral iron preparation containing calcium and magnesium.
- Humano is a supplementary preparation with a high iron content.
Disease monitoring
Monitoring of iron deficiency anemia involves regular monitoring of hemoglobin and serum iron levels. Monitoring steps may include:
- Evaluation of the dynamics of the patient's condition every 1-2 months during treatment.
- The prognosis with proper treatment is usually good.
- Complications may include cardiovascular disease if anemia is left untreated for a long time.
Age-related features of the disease
Iron deficiency anemia can manifest itself differently in different age groups. In newborns, it can occur due to insufficient iron in the mother's milk. In children and adolescents, the risk increases during periods of active growth. In women of reproductive age, anemia is more often associated with menstruation and pregnancy, while in older people it can be a consequence of chronic diseases.
Questions and Answers
- Can iron deficiency anemia be prevented? Yes, prevention is possible by following a balanced diet that includes iron-rich foods and, if necessary, by taking iron supplements.
- How long does treatment for iron deficiency anemia last? Typically the course of treatment is from 3 to 6 months, but this depends on the individual condition of the patient and can be extended if necessary.
- Which doctors should I see if I have iron deficiency anemia? It is recommended to consult a therapist, hematologist or gastroenterologist.
- Is there a risk of complications with iron deficiency anemia? Yes, untreated cases can lead to serious complications, including cardiovascular problems and deterioration of overall health.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov emphasizes the importance of regular checkups and hemoglobin levels for early detection of iron deficiency anemia. He recommends monitoring your diet and including at least 20-30% of the daily iron intake from foods, as well as avoiding excessive consumption of foods containing phytates (whole grains, legumes), which can interfere with iron absorption. Finally, maintaining an active lifestyle and regular medical checkups will allow you to correct your iron levels in a timely manner.
