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.

Can iron deficiency anemia be cured?

Iron deficiency anemia is one of the most common types of anemia clinically. The principle of treating iron deficiency anemia involves etiological treatment and symptomatic treatment. Etiological treatment means treating according to different causes, while symptomatic treatment involves correcting anemia and supplementing the raw materials for blood formation. The most common causes of iron deficiency anemia include gastrointestinal bleeding, internal hemorrhoids bleeding, hookworm and roundworm infections, malnutrition, and, notably in women, excessive menstrual bleeding and excessive bleeding during pregnancy and childbirth. These are common causes of iron deficiency anemia seen clinically. With the cause of iron deficiency anemia identified, the treatment often has a relatively high cure rate.

Iron deficiency anemia lacks what element?

Iron deficiency anemia refers to a type of anemia caused by a lack of stored iron in the body, which affects the synthesis of hemoglobin. Its characteristics include a lack of stainable iron in organs such as the bone marrow, liver, and spleen, leading to decreased serum iron concentration, decreased transferrin saturation, and decreased serum ferritin. Typical iron deficiency anemia presents as microcytic hypochromic anemia. Therefore, iron deficiency anemia involves a deficiency in iron, a trace element essential for the human body, which is widely present in cells and participates in the body's metabolic processes. The human body has a strict iron metabolism regulatory mechanism to maintain normal physiological levels. Once this homeostasis is disrupted, it can lead to the occurrence of iron deficiency anemia. Factors that affect the distribution, absorption, transport, and storage of iron can all cause iron deficiency anemia.

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.

What to eat for dietary supplementation in iron deficiency anemia

The dietary plan for patients with iron-deficiency anemia first involves increasing the intake of iron-rich foods, such as animal liver, blood, soybeans, black fungus, sesame paste, brown sugar, lean meat, egg yolks, pork and lamb kidneys, and dried fruits. Second, it is recommended to appropriately supplement with vitamin C, as taking iron supplements and vitamin C together can increase iron absorption, thereby achieving better iron supplementation effects. Thirdly, patients are advised to change their dietary habits to increase the intake and bioavailability of nutrients like vitamin A, vitamin B2, folic acid, and vitamin B12, which are involved in the production of red blood cells. Supplementing these nutrients can also enhance the utilization of iron from food, thereby assisting in the treatment.

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.
