Anemia is a deficiency in the size or number of red blood cells or in the amount of hemoglobin they contain.[1] This deficiency limits the exchange of O2 and CO2 between the blood and the tissue cells.[1] Globally, young children, women, and older adults are at the highest risk of developing anemia.[1] Anemia can be classified based on different parameters, and one classification depends on whether it is related to nutrition or not so there are two types: nutritional anemia and non-nutritional anemia.[1] Nutritional anemia refers to anemia that can be directly attributed to nutritional disorders or deficiencies. Examples include Iron deficiency anemia and pernicious anemia.[2] It is often discussed in a pediatric context.[3][4][5][6]
According to the World Health Organization, a hemoglobin concentration below 110 g/L for children under 5 years of age and pregnant women, and below 130 g/L for men indicates anemia. Hemoglobin is a blood protein that transports oxygen to the cells of the body. Without oxygen, the human body cannot undergo respiration and create Adenosine triphosphate, thereby depriving cells of energy.[7]
Nutritional anemia can be caused by a lack of iron, protein, vitamin B12, and other vitamins and minerals that are needed for the formation of hemoglobin. However, Iron deficiency anemia is the most common nutritional disorder.[7]
Signs of anemia include cyanosis, jaundice, and easy bruising.[7] In addition, anemic patients may experience difficulties with memory and concentration, fatigue, lightheadedness, sensitivity to temperature, low energy levels, shortness of breath, and pale skin. Symptoms of severe or rapid-onset anemia are very dangerous as the body is unable to adjust to the lack of hemoglobin. This may result in shock and death. Mild and moderate anemia have symptoms that develop slowly over time.[5] If patients believe that they are at risk for or experience symptoms of anemia, they should contact their doctor.[8]
