Patients with iron deficiency anemia mostly suffer from anemia due to lack of iron, but in a small proportion of cases, the essence of their anemia is due to the number of red blood cells or hemoglobin per unit volume of blood being below normal levels. Therefore, any factor that can lead to reduced production or excessive destruction, or loss of red blood cells or hemoglobin can cause anemia. Can patients with iron deficiency anemia consume vitamin C? The main treatment plan for iron deficiency anemia includes four aspects. First, general treatment aims to prevent and reduce various factors that induce iron deficiency. Second, etiological treatment involves identifying a cause whenever possible and controlling the primary iron deficiency related to that cause, such as actively combatting hookworm infection in cases of hookworm disease, stopping bleeding and actively treating ulcers in cases of ulcerative bleeding, and actively controlling menstrual flow in women with heavy periods. Third is the supplementation of iron, which should ideally be taken with vitamin C as it can enhance the absorption of iron. Therefore, patients with iron deficiency anemia can indeed consume vitamin C.

Characteristics of iron deficiency anemia blood picture

The clinical manifestations of iron deficiency anemia are due to the specific characteristics of anemia caused by iron deficiency and the underlying disease causing the iron deficiency. Its hematological characteristics present as typical microcytic hypochromic anemia. What does this concept mean? It refers to the values in a complete blood count where MCV is less than 80 femtoliters, MCH is less than 27 picograms, and MCHC is less than 30%. MCV refers to the average red blood cell volume, MCH refers to the mean corpuscular hemoglobin concentration, and MCHC refers to the mean corpuscular hemoglobin concentration of red blood cells. The extent of changes in red blood cell indices correlates with the duration and severity of anemia. The blood smear typically shows pale-stained red blood cells with an enlarged central pallor and varying sizes. Platelet count often tends to be high when there is concurrent bleeding and generally tends to be low in infants and children. White blood cell count is usually normal or slightly reduced, with normal differential. These are the hematological characteristics of iron deficiency anemia.

Iron deficiency anemia lacks iron.

Iron deficiency anemia is an anemia caused by the lack of stored iron in the body, affecting the synthesis of hemoglobin. It is characterized by a lack of stainable iron in the bone marrow, liver, spleen, and other organ tissues, as well as decreased serum iron concentration, transferrin saturation, and ferritin levels, typically presenting as microcytic hypochromic anemia. Thus, iron deficiency anemia refers to a deficiency of iron. Iron is an essential trace element in the human body, involved in cellular functions and metabolic processes. The body has a strict regulatory mechanism for iron metabolism to ensure that iron levels are always maintained at a normal level, referred to as iron homeostasis. Iron homeostasis relies crucially on the balance between intestinal iron absorption and the body's iron requirements. Once this balance is disrupted, problems in iron distribution, absorption, transport, and storage may occur, leading to iron deficiency anemia.

What indicators are used to diagnose iron deficiency anemia?

For iron deficiency anemia, a complete blood count should first be considered. The blood count presenting as microcytic hypochromic anemia often suggests the possibility of iron deficiency anemia. Microcytic hypochromic anemia is characterized by a decrease in hemoglobin, a decrease in mean corpuscular volume, a decrease in mean corpuscular hemoglobin concentration, and a decrease in mean corpuscular hemoglobin. When the complete blood count indicates the possibility of iron deficiency anemia, further investigation into iron-related indices is required, such as decreased serum iron, decreased ferritin, decreased transferrin saturation, and increased soluble transferrin receptor capacity.

Symptoms of iron deficiency anemia

The clinical manifestations of iron deficiency anemia consist of symptoms due to the anemia itself, specific manifestations of iron deficiency, and the underlying diseases causing the iron deficiency. The onset of anemia is often insidious, with some patients progressing very slowly. Initially, patients can adapt well to daily life and continue with their work, making it difficult to detect. It is usually not until the anemia becomes moderate to severe and symptoms become apparent that it is discovered. Common symptoms of anemia include dizziness, headaches, weakness, easy fatigue, palpitations, and shortness of breath after activity. Some patients might also experience a decline in memory and suffer from tinnitus and blurred vision. Some affected children may exhibit delayed growth and development or even abnormal behaviors, which can manifest as irritability, restlessness, inattention in class, and declining academic performance. A few patients may develop pica, a specific manifestation of iron deficiency anemia. Additionally, some patients might suffer from angular cheilitis, glossitis, and even atrophy of the tongue papillae. Severe cases can experience transient blindness and fainting, hence it is crucial to seek medical attention for iron deficiency anemia at the earliest.

What department should I go to for iron deficiency anemia?

Anemia refers to a condition in which the total volume of red blood cells in the circulating blood is reduced below normal levels, resulting in anemia. Iron deficiency anemia is a type of anemia caused by a lack of hematopoietic raw materials. Iron deficiency anemia occurs when the body's stored iron is depleted and cannot meet the needs for normal red blood cell production. As the most common type of red blood cell disease, iron deficiency anemia falls within the category of hematology. Therefore, patients with iron deficiency anemia should seek specialized consultation in the department of hematology. Furthermore, we recommend seeking medical advice as early as possible since moderate to severe iron deficiency anemia can lead to a series of circulatory disorders, thereby exacerbating the condition.
