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 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.

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.

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.

The hazards of anemia in pregnant women

Firstly, the occurrence of anemia during pregnancy is very common, and most cases are mild anemia, but a small proportion can be severe. The harm of anemia comes from two aspects: one is that it is harmful to the fetus, as anemia during pregnancy can affect the intellectual development of the fetus, which is very clear. Another harm comes from the mother, such as the possibility of postpartum hemorrhage or infection. If a cesarean section is performed, our hemoglobin must not be lower than 80 grams. If it is below 80 grams, a blood transfusion or intraoperative blood preparation is needed.
