The formed elements in the blood include red blood cells, white blood cells, and platelets, which play important roles in cellular metabolism, defense, and hemostasis, respectively. Among them, anemia falls under the category of red blood cell diseases. Iron-deficiency anemia refers to a condition where the body's iron stores are depleted, failing to meet the needs for normal red blood cell production. Before the production of red blood cells is restricted, the body's iron stores are already depleted, but anemia has not yet occurred, a condition we call iron deficiency, also known as the subclinical iron deficiency period clinically. Iron-deficiency anemia is a common red blood cell disease and falls under the category of hematology. Therefore, patients with iron-deficiency anemia should consult a specialist in hematology.

What is good to eat for iron deficiency anemia?

The treatment of iron deficiency anemia mainly includes two aspects. One is the treatment targeted at correcting anemia caused by iron deficiency, and the other is identifying the cause of iron deficiency in the body and correcting it. Iron deficiency anemia is caused by chronic blood loss and a relative deficiency in iron intake due to increased iron demand in the body, which leads to reduced red blood cell production. The main treatment is to supplement with iron-rich medications, and one can also consume more lean meat, pork liver, duck blood, spinach, black fungus, and other foods rich in iron. For patients with iron deficiency anemia, it is crucial to identify the cause of the iron deficiency and provide targeted treatment to fundamentally resolve the issue of iron deficiency anemia.

Does iron deficiency anemia cause tiredness?

Patients with iron-deficiency anemia can exhibit symptoms of fatigue. Anemia is characterized by red blood cells and hemoglobin levels that are below the normal range. Red blood cells are the main cells responsible for transporting oxygen in the body. Oxygen enters the blood through gas exchange in the lungs and is then delivered throughout the body by red blood cells to supply oxygen. Therefore, patients with anemia will show varying degrees of ischemia and hypoxia. In the nervous system, this can be manifested as lethargy, insomnia, frequent dreaming, tinnitus, blurry vision, fainting, and lack of concentration. As the severity of anemia increases, these symptoms may also worsen. Patients with severe anemia may exhibit significant lethargy and drowsiness.

Consequences of untreated iron deficiency anemia

Any anemia, if not treated, will only get worse over time, including iron-deficiency anemia. Prolonged anemia can impact various organ systems throughout the body. In the nervous system, it can cause headaches, dizziness, insomnia, frequent dreams, and memory decline. In children, iron-deficiency anemia can even affect intellectual development. In the respiratory system, it can lead to deeper and faster breathing, and increase the risk of respiratory infections. In the circulatory system, it can manifest as low blood volume, and long-term severe anemia can lead to anemic heart disease, causing arrhythmias and heart failure. In the digestive system, it can manifest as reduced appetite, and in severe cases, it can cause constipation, diarrhea, etc.

Causes of Iron Deficiency Anemia

There are many reasons for iron deficiency anemia, which we can categorize into several aspects. The first aspect is a decrease in iron intake, including diet, meaning insufficient dietary intake. The second aspect is decreased absorption, such as the absence of a target organ for absorption or the lack of stomach acid affecting its absorption efficacy. The second aspect refers to excessive loss, most commonly chronic gastrointestinal bleeding, such as in patients with tumors, duodenal ulcers, gastric ulcers, gastritis, ulcerative colitis, a parasitic infection with hookworms, as well as hemorrhoids, and arteriovenous malformations, all of which can cause gastrointestinal bleeding leading to increased iron loss. Excessive menstrual flow in female patients, multiple blood donations, and multiple pregnancies can all lead to iron deficiency. These are the various causes related to iron deficiency.

Iron deficiency anemia clinical symptoms

The clinical manifestations of iron deficiency anemia include symptoms caused by ischemia-induced tissue and organ hypoxia, as well as specific clinical signs associated with iron deficiency. Common clinical manifestations of iron deficiency anemia often include dizziness, headache, fatigue, easy tiring, memory decline, shortness of breath and palpitations after activities, and even symptoms such as tinnitus and blurred vision. Specific signs of iron deficiency include stomatitis, glossitis, atrophic gastritis, dry skin, brittle and falling hair, flat or spoon-shaped nails that are thin and prone to cracking. Some patients may also experience pica and difficulty swallowing, all of which are clinical manifestations of iron deficiency anemia.
