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.

What should pregnant women do about anemia?

We often find that anemia in pregnant women is very common during prenatal check-ups. There are three main reasons for anemia. The first reason is iron deficiency anemia, which is due to insufficient intake during pregnancy while the fetus requires a large amount, leading to iron deficiency anemia. The second reason is megaloblastic anemia, which is caused by insufficient intake of vitamin B6 and folic acid, resulting in anemia. Another condition is thalassemia, which is due to a genetic mutation causing anemia. For treatment of anemia, we first need to address the specific cause. If it is iron deficiency anemia, iron supplements are necessary, and the diet should include foods like pork liver and lean meat. If it is megaloblastic anemia, supplementation with folic acid and vitamin B12 is needed. Moreover, for thalassemia, mild cases can be observed, while severe cases may require a small amount of blood transfusion treatment.

Can anemic people donate blood?

Patients with anemia cannot donate blood. After donating blood, due to the reduction of blood volume, it may worsen anemia and cause symptoms such as dizziness, excessive sweating, nausea, vomiting, and other manifestations of low blood pressure. In severe cases, it can even induce acute cardiovascular and cerebrovascular accidents, so patients with anemia cannot donate blood. Clinically, the requirements for blood donors include not being anemic, weighing more than 45 kilograms, and being free of infectious diseases.

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.

Iron deficiency anemia is a type of anemia.

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.
