Anemia can be categorized into several different types, each caused by different reasons. Iron-deficiency anemia occurs in late pregnancy when the intake or absorption of iron by pregnant women is insufficient. Megaloblastic anemia is caused by a deficiency of folate or vitamin B12 in the patient's body. Additionally, there is thalassemia, which is caused by a genetic deficiency in the patient, leading to anemia in the fetus as well. Another type is aplastic anemia, which is caused by abnormal bone marrow hematopoietic function leading to anemia.

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.

How to recuperate from anemia

How to nourish anemia depends on the specific cause of the anemia, and it varies with the specific cause. If the anemia is nutritional, this type is due to a lack of hematopoietic materials such as folic acid, vitamin B12, and iron. In this case, it is necessary to actively supplement these hematopoietic materials, including eating foods that are rich in these materials. However, if the cause of anemia is due to leukemia, aplastic anemia, myeloma, lymphoma, etc., then it is necessary to treat the underlying disease to improve the anemia. In addition, patients with anemia need to pay attention to rest, prevent catching cold, and prevent infections.

Symptoms of low blood pressure and anemia

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 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.

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.
