Main clinical symptoms of low blood pressure and anemia: general fatigue, pale complexion, heart palpitations and shortness of breath, cerebral ischemia causing dizziness and vertigo, insomnia and frequent dreams; some patients may also experience loss of appetite, indigestion, and other symptoms. Low blood pressure and anemia are not the same disease, and their clinical treatments differ. Low blood pressure is caused by excessively low blood pressure leading to ischemia above the brain, and the treatment should aim to increase blood volume and elevate blood pressure. Anemia is caused by a reduction in hemoglobin, leading to ischemia and hypoxia in the body, and treatment should involve supplementation of nutrients and the essential trace elements that are lacking, which should be treated seriously.

How to deal with anemia and dizziness?

Dizziness during anemia is caused by the anemia itself, as the body is in a state of ischemia and hypoxia during anemia, leading to dizziness due to ischemia and hypoxia in the nervous system. In addition to dizziness, there is also a feeling of heavy-headedness and headaches. To quickly improve these symptoms, it is necessary to transfuse red blood cells and correct the anemia. However, after correcting the anemia, due to the limited lifespan of red blood cells, if the cause of the disease is not clearly identified and treated accordingly, the patient will still experience anemia and symptoms like dizziness again.

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.

How to check for anemia?

Anemia requires an initial routine blood test, which is a complete blood count. If it indicates a reduction in red blood cell count and a significant decrease in hemoglobin, it suggests anemia. Once anemia is indicated by the complete blood count, further tests are guided by the size of the red blood cell volume. If it is microcytic anemia, common types include iron deficiency anemia and anemia of chronic disease, and tests such as serum iron, ferritin, and tumor markers are needed. If it is normocytic anemia, a bone marrow biopsy is required to rule out aplastic anemia, multiple myeloma, etc. If it is macrocytic anemia, tests for folate and vitamin B12 are needed to exclude myelodysplastic syndrome and megaloblastic anemia, among others.

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.

How should pregnant women supplement for anemia?

Under normal circumstances, if anemia symptoms are confirmed after pregnancy, further examination is still necessary for active symptomatic treatment. Normally, the specific cause of the anemia can be identified, whether it is due to iron deficiency, folate deficiency, or B12 deficiency. According to the specific cause of anemia, oral medication can be administered for symptomatic treatment, which can effectively alleviate the symptoms. After taking oral medication, it is also necessary to regularly check the rise in hemoglobin levels to properly manage the condition.
