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.

Which department should I go to for anemia?

Anemia is classified as a hematological disease and requires further diagnosis and treatment in the department of hematology. In severe cases of anemia, the body can be in a state of ischemia and hypoxia, which can induce the occurrence of acute cardiovascular and cerebrovascular diseases, such as acute angina and cerebral thrombosis. Therefore, patients with acute anemia need to have red blood cell transfusions to support treatment and correct the anemia. If the anemia is not severe, red blood cell transfusion is not necessary, but it is important to complete tests like anemia indicators, bone marrow aspiration, and bone marrow biopsy to further clarify the cause of the anemia and treat it accordingly.

Can anemia cause tinnitus?

Anemia can cause tinnitus. When anemia is severe, various organs of the body are in a state of ischemia and hypoxia. The nervous system can exhibit symptoms such as dizziness, headaches, and a feeling of heaviness in the head, as well as tinnitus. At this point, infusing red blood cells to correct the anemia can alleviate symptoms like tinnitus. It is also important to actively seek the underlying causes of the anemia. Anemia can be categorized based on the size of red blood cells into microcytic hypochromic anemia, normocytic anemia, and macrocytic anemia. Microcytic hypochromic anemia is commonly seen in chronic disease anemia and iron deficiency anemia, normocytic anemia is commonly found in conditions such as leukemia, multiple myeloma, and acute blood loss anemia, while macrocytic anemia is typical in megaloblastic anemia and myelodysplastic syndromes.

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.

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.

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.
