Anemia is a condition resulting from insufficient red blood cells or decreased quantity of hemoglobin. This affects the body's ability to transfer oxygen and results to symptoms such as fatigue, difficulties in breathing and lightheadedness.
Chronic inflammation Anemia
This type of anemia is related to systemic diseases such as, arthritis, chronic infections like tuberculosis and HIV. These conditions cause major changes in the body's blood cells. Red blood cells' lifespan is reduced, and production of new red blood cells reduces. The body withholds iron so that it cannot be utilized to create new blood cells (Roy, 2010). The body usually recycles iron from the red blood cells and uses it to generate new cells. In inflammation anemia, the body fails to recycle iron easily. Symptoms include; fatigue, headache, dizziness, difficulties in breathing, lack of energy and lethargy (Roy, 2010).
Iron deficiency Anemia
Iron-deficiency anemia is most common among patients. It develops when the body lacks sufficient iron required to produce hemoglobin which transfers oxygen to body tissues (Cafasso, 2012). Body muscles and tissues require oxygen in order to function effectively. Iron-deficiency anemia can result due to medical conditions that cause internal bleeding such as stomach ulcers, or colon cancer. Certain diseases such as celiac disease can also affect the intestines ability to absorb iron (Cafasso, 2012).
sideroblastic anemia
sideroblastic anemia is caused by dysfunctional heme synthesis or processing. This results to granular deposition of iron inside the mitochodria that develop into a ring around the nucleus o...
