Anemia: Iron Deficiency Anemia
built 635 days ago
Anemia of chronic disease... called anemia of malignancy, is the most common type of anemia seen in individuals with cancer. It is a diagnosis made only after other possible causes are ruled out and if very specific conditions are met. The presence of low levels of iron coupled with normal levels of storage iron helps distinguish anemia of chronic disease from iron deficiency anemia. Factors that cause anemia of chronic disease are not entirely clear. However, it is believed that cytokines (non-antibody proteins) produced by the tumor reduce production of and impair responsiveness to erythropoietin. Typically, this type of anemia develops slowly.

Anemia is a prevalent condition with a variety of underlying causes. Once the etiology has been established, many forms of anemia can be easily managed by the family physician. Iron deficiency, the most common form of anemia, may be treated orally or, rarely, parenterally. Vitamin B12 deficiency has traditionally been treated with intramuscular injections, although oral and intranasal preparations are ... available. The treatment of folate deficiency is straightforward, relying on oral supplements. Folic acid supplementation is also recommended for women of child-bearing age to reduce their risk of neural tube defects (Little 199

Anemia ... occurs when the body isn't able to produce enough healthy RBCs because of an iron deficiency. Iron is essential to hemoglobin production. Poor dietary iron intake (or excessive loss of iron from the body) can lead to iron deficiency anemia, the most common cause of anemia in children. Iron deficiency anemia can affect children at any age, but is most commonly seen in those younger than 2 years old.

Anemia occurs when the amount of hemoglobin (found in the red blood cells) drops below normal. Hemoglobin is necessary for the transportation of oxygen throughout the body. Blood test for anemia may show a normal or low hemoglobin, decreased iron, ferritin, and all red blood cell indices. The total iron-binding capacity (TIBC) or transferrin will be increased. The ferritin test is considered to be the most specific for identifying iron deficiency anemia.

Anemia can be confirmed by measuring the hemoglobin levels of the body. An iron deficiency can be identified by blood cell analysis and by determining the serum ferritin level and , if necessary, the amount of haemoisderin in the bone marrow. Young people store only small amounts of iron, and low serum ferritin levels are therefore normal in individuals under the age twenty. The examining doctor needs expert knowledge in order to be able to decide whether or not an apparent iron deficiency is really significant. On the whole, it is not most common for adults on a well-balanced diet to suffer from iron deficiency.

Anemia is caused by bleeding, decreased red blood cell production, or increased red blood cell destruction. Poor diet can contribute to vitamin deficiency and iron deficiency anemia, in which fewer red blood cells are produced. Hereditary disorders and certain diseases can cause increased blood cell destruction. However, excessive bleeding is the most common cause of anemia, and the speed with which blood loss occurs has a significant effect on the severity of symptoms. Chronic blood loss may be caused by:
