Anemia is a condition in which the total volume of red blood cells in the circulating blood is reduced below the normal value. Iron deficiency anemia belongs to a category of anemia caused by a lack of hematopoietic raw materials. It occurs when the body's stored iron is depleted and cannot meet the needs for normal red blood cell production. Iron deficiency anemia is a common disease among red blood cell disorders and is categorized under anemias caused by a deficiency in hematopoietic raw materials.

Symptoms of anemia in late pregnancy

Patients with mild anemia in the late stage of pregnancy may not exhibit any obvious symptoms. However, patients with severe anemia may feel a lack of energy and dizziness throughout the body, and experience symptoms such as palpitations and shortness of breath after doing just a little bit of activity. Additionally, some individuals may experience gastrointestinal symptoms, such as abdominal bloating and diarrhea. Moreover, those affected may have a reduced appetite. In anemic women, signs on the skin and mucous membranes include pallor, dry skin, and sparse hair. Additionally, the nails may also be fragile and thin, and there is an increased likelihood of developing oral inflammation and similar symptoms.

How is anemia treated?

Patients with severe anemia require red blood cell transfusion as supportive treatment. If the degree of anemia is not severe, blood transfusion is not necessary. All anemic patients should undergo relevant examinations to determine the cause of the anemia, which can then inform the treatment plan to address the underlying cause. For instance, patients with nutritional anemia need to receive treatment that supplements the materials necessary for blood formation; in cases of anemia caused by malignant hematologic diseases such as leukemia or myeloma, chemotherapy is required to treat the primary disease; for patients with acute hemorrhagic anemia, it is necessary to identify and correct the cause of the blood loss.

How to supplement baby's anemia?

The treatment for childhood anemia primarily focuses on addressing the underlying cause. Nutritional anemia is the most common type of anemia in children, which includes iron-deficiency anemia and megaloblastic anemia. For iron-deficiency anemia, the main treatment is iron supplementation. This can be done through dietary means, such as increasing the intake of foods high in iron like pork liver and egg yolks. Additionally, treatment should address any underlying causes of iron deficiency. For instance, if parasitic infections are causing blood loss, then treating the parasitic infection is necessary. If the anemia is due to poor dietary habits or picky eating, then changing these habits is crucial. If general treatments are ineffective, then oral iron supplements should be considered. In the case of megaloblastic anemia, it is important to address the vitamin deficiencies that cause it, namely the lack of folate and vitamin B12. Supplementation of folate and vitamin B12 is recommended.

Anemia lacks what element

Anemia is not always caused by a deficiency in elements. In cases of iron deficiency anemia, it is due to a lack of iron. Megaloblastic anemia occurs because of a deficiency in folate or vitamin B12. However, clinically, there are many other types of anemia, such as aplastic anemia, hemolytic anemia, myelodysplastic syndromes, leukemia, etc. The anemia caused by these diseases is not due to a deficiency in elements, but is due to the diseases themselves affecting bone marrow hematopoiesis, leading to anemia. Therefore, it is necessary to clearly diagnose the cause of anemia in order to treat it effectively.

Can anemia cause fever?

Patients with severe anemia may exhibit low-grade fever due to the severity of the anemia, where the fever generally does not exceed 38 degrees Celsius, mostly hovering around 37.5 degrees Celsius. Besides, if a patient with anemia develops high fever above 38 degrees Celsius, even reaching around 39 degrees Celsius, it is crucial to be vigilant about a possible secondary infection due to poor resistance from anemia. It is important to actively search for the source of infection, complete tests such as inflammatory markers, CT scans, and ultrasound imaging, and, once an infectious fever is suspected, to initiate aggressive anti-infection treatment.
