Adolescents with Anemia
To comprehend anemia, one must first comprehend breathing. Inhaled oxygen simply does not stop in the lungs. It circulates throughout the body and provides energy to the brain. The bloodstream transports oxygen to all parts of the body, specifically the RBCs (red blood cells). These RBCs are now produced in the body’s bone marrow and serve as oxygen-carrying boats in the bloodstream. Hemoglobin, a protein found in RBCs, is responsible for storing oxygen. Iron is required in large quantities by the body in order to produce adequate hemoglobin. Iron, along with other nutrients, is provided by the foods we eat. When the number of RBCs in the body falls below what is required, anemia develops. There are three main reasons for this: RBCs are lost for various reasons, RBC production is slower than required, and the body destroys RBCs. At least one of these causes is linked to various types of anemia.
The bone marrow replaces small amounts of blood that are lost due to various factors without causing anemia. However, in cases where a large amount of blood flows in a short period of time, such as as a result of a serious injury, bone marrow may not be able to replace RBCs as quickly, resulting in anemia. Anemia can also be caused by losing small amounts of blood over a long period of time. Girls with heavy periods, which are primarily due to a lack of iron in their diet, are an example of this situation.
The most common type of anemia in the United States is iron deficiency anemia. It is caused by a person’s diet lacking in iron. A teen with an iron deficiency would produce less hemoglobin and, as a result, have fewer RBCs. When a person’s RBC production is low, he or she is considered anemic. Paleness and exhaustion are symptoms of anemia. There may be other reasons why the body does not produce enough RBCs. RBC production also requires folic acid and vitamin B-12. It’s also critical to obtain these in sufficient quantities. Anemia can also be caused by a problem with the bone marrow’s function.
Hemolytic anemia occurs when a person’s RBCs have a shorter lifespan. If the blood cells die too soon, the bone marrow may be unable to produce new blood cells. This can happen for a variety of reasons, including people who have spherocytosis or sickle cell anemia. RBCs may be destroyed by the body’s immune system in some cases. Certain antibodies can form in the blood as a result of a reaction to drugs or infections, and these antibodies can attack RBCs.
Teens get anemia because they grow so quickly that their iron intake may not be enough to keep up with the rate of growth, which necessitates more nutrients. Girls require more iron after puberty and are particularly vulnerable due to heavy blood loss during menstrual periods. Pregnancy can cause anemia in some women. Additionally, teenagers who diet excessively to lose weight may be at risk of iron deficiency. Meat eaters, particularly red meat eaters, are less at risk than vegetarians because meat contains a lot of iron.
