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.

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.

What indicators are used to diagnose anemia?

To determine if someone is anemic, we should look at the red blood cell count and hemoglobin level in a complete blood count. Currently, hemoglobin level is the commonly used indicator clinically. Normal hemoglobin levels are 110~150g/L for women and 120~160g/L for men. Anemia is diagnosed when the hemoglobin level falls below the normal range. Based on the amount of hemoglobin, anemia can be classified into very severe, severe, moderate, or mild. Hemoglobin levels above 90g/L indicate mild anemia, levels between 60~90g/L indicate moderate anemia, levels between 30~60g/L indicate severe anemia, and levels below 30g/L indicate very severe 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.
