Nutritional anemia

Iron deficiency is the most common nutritional disorder worldwide and accounts for approximately one-half of anemia cases. The diagnosis of iron deficiency anemia is confirmed by the findings of low iron stores and a hemoglobin level two standard deviations below normal. Women should be screened during pregnancy, and children screened at one year of age. Supplemental iron may be given initially, followed by further workup if the patient is not responsive to therapy. Men and postmenopausal women should not be screened, but should be evaluated with gastrointestinal endoscopy if diagnosed with iron deficiency anemia. The underlying cause should be treated, and oral iron therapy can be initiated to replenish iron stores. Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations. Clinical recommendation Evidence rating References Measurement of the serum ferritin level is the most accurate test to diagnose iron deficiency anemia.

Many people think that anemia is the lack of blood in the human body. Some people even believe that low blood pressure is also anemia. In fact, these concepts are wrong. The total amount of blood in an anemic person is not less. What is missing in an anemic person is the number of red blood cells in the blood. So, it is possible to determine whether people are anemic by measuring hemoglobin (Hb). For anemia, the WHO has clear criteria. Hb in the blood of an adult male is lower than that of 130g/L. For adult females, Hb in the blood is less than 120g/L. For children aged six months to six years, Hb in the blood is less than 110g/L. Hb in the blood of 6 ~ 14 years children is lower than that of 120g/L. For pregnant females, Hb in the blood is less than 110g/L. The standard for judging anemia in China is slightly lower than WHO. Hb in the blood of an adult male is lower than that of 120g/L. Hb in the blood of an adult female is lower than that of 110g/L. For pregnant females, Hb in the blood is less than 100g/L. Among them, those with Hb less than 30g/L are very severe anemia. Those with 30-60g/L are severely anemic. Those with 60~90g/L are moderate anemia. 90g/L＜Hb＜110g/L is mild anemia. The lack of certain nutrients in the body can cause people to develop nutritional anemia. Nutritional anemia includes hypochromic anemia and megaloblastic anemia. A lack of iron (Fe) in the body can lead to hypochromic anemia. The deficiency of vitamin B9 or vitamin B12 in the body can lead ...

Macrocytic anemia causes large red blood cells that cannot carry enough oxygen throughout the body. The symptoms mimic other kinds of anemia but the treatment depends on the underlying cause. This article looks at the causes and symptoms of macrocytic anemia, the treatment options, and how to prevent complications. Share on Pinterest Azman Jaka/Getty Images Macrocytosis is a term that describes a condition in which a person’s blood cells are too large. It often occurs along with anemia, a condition in which there are either not enough healthy red blood cells to carry oxygen to all the tissues or the existing cells are not as efficient. Doctors use a unit called femtoliters to measure the size of blood cells. Usually, red blood cells are between When the cells grow too large, there are fewer of them, and they contain less hemoglobin. This means the blood is not as oxygen-rich as it should be. Low blood oxygen can cause a range of symptoms and health problems. Doctors classify macrocytosis into • Megaloblastic macrocytosis: This is the most common form. It occurs when a person cannot produce DNA because of a B12 or folate deficiency. • Nonmegaloblastic macrocytosis: This can happen when there is a liver, spleen, or bone marrow problem. Both of these types can occur along with anemia. One of the most common is megaloblastic. Anemia develops gradually, so a person may not notice any symptoms until it is severe. When symptoms appear, they may include: • weakness • paleness • ex...
