First of all, iron deficiency anemia during pregnancy is very common, and it is also a very common complication we encounter in prenatal screening. The reason for anemia during pregnancy is due to the increased demand for iron as the fetus grows, and maternal intake is insufficient.

Iron deficiency anemia can lead to severe bleeding during childbirth, and if a cesarean section is performed, it may adversely affect the healing of the incision. Furthermore, iron deficiency anemia may affect fetal intelligence.

Therefore, it is crucial to ensure proper prenatal screening during pregnancy to prevent severe anemia. If anemia is severe, blood transfusion treatment may be necessary during childbirth or cesarean delivery.

What department should I go to for iron deficiency anemia?

Iron is one of the essential trace elements for the human body, and it is the most likely to be deficient among trace elements. Iron deficiency can lead to iron deficiency anemia, which is also identified by the World Health Organization as one of the global nutritional deficiency diseases and a major public health nutrition issue in China. According to epidemiological surveys, iron deficiency is related to the following factors: improper feeding during infancy, picky eating and nosebleeds during childhood and adolescence. In women, it is associated with excessive menstrual flow, poor nutrition, inadequate protein intake (especially low intake of animal proteins), inappropriate consumption methods of dairy products, as well as repeated pregnancies, breastfeeding, and certain diseases such as atrophic gastritis, chronic diarrhea, significant gastric resection, and hookworm infections, all of which can cause iron deficiency. Therefore, patients with iron deficiency anemia should consult the department of hematology, as iron deficiency anemia falls under the category of red blood cell disorders within hematology. Of course, infants, children, and adolescents under the age of 14 can visit pediatrics, and a portion of patients, such as pregnant and lactating women, can visit the obstetrics department.

Diet for Iron Deficiency Anemia

Patients with iron-deficiency anemia need to undergo pharmacological treatment with oral or injective iron supplements. In addition, patient health education should be enhanced to guide them in following a scientific and reasonable diet. For example, patients who are picky eaters or have insufficient intake should change their dietary structure and lifestyle in order to increase iron intake and bioavailability. This ensures that all key nutrients involved in the production of red blood cells are sufficient. Moreover, it is necessary to increase the intake of iron-rich foods, mainly including animal liver, blood, as well as soybeans, black fungus, egg yolks, brown sugar, lean meat, sheep kidneys, dried fruits, and sesame paste.

Does iron deficiency anemia cause a yellow complexion?

No matter what type of anemia, it manifests as a decrease in hemoglobin. Red blood cells are the main cells that carry oxygen, so patients with anemia will have signs of ischemia and hypoxia to some extent, and anemia manifests as pallor in the skin and mucous membranes. Since Chinese are of the yellow race, the manifestation of anemia in Chinese patients often appears as a yellowish complexion. Therefore, patients with iron deficiency anemia can have a yellowish complexion. Of course, if there is obvious yellowing of the skin and sclera in addition to the yellowish complexion, further tests such as hemolysis indicators are needed to rule out hemolytic anemia, as patients with hemolytic anemia often have concurrent jaundice.

What is the fastest way to treat iron deficiency anemia?

Iron deficiency anemia is a type of anemia caused by a lack of storage iron in the body, affecting the synthesis of hemoglobin. It is characterized by a lack of available iron in tissues and organs such as bone marrow, liver, and spleen, with decreased serum iron concentration, transferrin saturation, and serum ferritin levels. Typically, iron deficiency anemia presents as microcytic hypochromic anemia. Iron, as one of the essential trace elements in the human body, is contained in all functioning cells and is broadly involved in metabolic processes within the body. Therefore, the treatment principle for iron deficiency anemia involves replenishing sufficient iron until normal iron stores are restored and addressing the underlying causes that led to the iron deficiency to effectively and quickly replenish iron. Oral iron supplements are the preferred treatment option for iron deficiency anemia, such as ferrous sulfate, ferrous succinate, and iron dextran which are effective oral iron agents.

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.
