For example, iron deficiency anemia generally has a low average body volume in addition to low hemoglobin. The term “anemia” generally refers to a condition in which the blood has a lower than normal number of red blood cells. In pernicious anemia, the body cannot produce enough healthy red blood cells because it does not have enough vitamin B12.
Red blood cell transfusions will only provide temporary improvement. It is important to know why he is anemic and to treat cause and symptoms. Indeed, iron is an important element of hemoglobin and essential to its proper functioning. Chronic blood loss for whatever reason is the main cause of low levels of iron in the body, as it depletes the body’s iron supply to compensate for the continued loss of iron. Anemia due to low iron levels is called iron deficiency anemia. Renal impairment in people with kidney disease can cause chronic anemia if the disease interferes with the production of erythropoietin in the kidneys.
George Minot and George Whipple set out to chemically isolate the curative substance and were finally able to isolate vitamin B12 from the liver. Megaloblastic anemia, the most common cause of macrocyte anemia, is due to a deficiency of vitamin B12, folic acid or both. Folic acid or vitamin B12 deficiency may be due to inadequate or insufficient absorption. Folate deficiency generally does not produce neurological symptoms, unlike B12 deficiency.
With the inherited type, parents transmit the genes of the condition to their children. Two common causes of this type of anemia are sickle cell anemia and thalassemia. These conditions produce red blood cells that do not live as long as normal red blood cells. Anemia is more common in people with chronic kidney disease and can be caused by their NDE. Anemia occurs when there are not enough red blood cells in your body. When your kidneys are not working as they should, your body may make fewer red blood cells.
Sick kidneys can also cause the body to absorb less iron and folic acid, nutrients needed to create red blood cells. A history of certain infections, blood diseases and autoimmune disorders increases the risk of anemia. Alcoholism, exposure to toxic chemicals and the use of certain drugs can affect the production of red blood cells and cause anemia. The only way to know if you have anemia is to have a blood test. When you have kidney disease, your doctor will want you to have frequent blood tests. These tests are used to check not only your kidney function, but also to detect signs of any other problem, such as the number of red blood cells and the amount of iron in your body.
Anemia is a general term for having very few red blood cells in the blood. Red blood cells transport oxygen and nutrients through the bloodstream to body cells. The most important element of red blood cells is called hemoglobin. Hemoglobin is a protein that carries oxygen to the blood from the lungs to the cells of the body. Anemia occurs when the body produces very few healthy red blood cells; the body loses blood; or the body destroys the red blood cells in circulation.
Babies, young children and pregnant women have above average needs. An increase in iron intake is also necessary to compensate for blood loss due to digestive tract problems, frequent blood donation or heavy menstruation. Iron is an essential part of hemoglobin, and low levels of iron cause a decrease in the incorporation of hemoglobin into red blood cells. In the United States, 12% of all women of childbearing age are deficient in iron, compared to only 2% of adult men.
Transferrin is a protein that helps transport iron from the intestines to the bloodstream. Methods have been developed to allow reliable measurement of hepcidine in plasma, but are not available or approved for use in the diagnosis of chronic anemia today. Anemia is characterized by low levels of circulating red blood cells or hemoglobin, the part of red blood cells that carries oxygen. In mild cases, anemia may not be associated with symptoms or may cause fatigue, pallor of the skin and dizziness. The underlying mechanisms that cause chronic anemia are complex and poorly understood. When anemia occurs slowly, symptoms are often vague and may include a feeling of tiredness, weakness, shortness of breath and poor ability to exercise.
Very often chronic diseases prevent your body from effectively using iron to create new red blood cells, even if there are normal or high levels of iron stored in the body. 經血過多 The treatment of certain diseases may also affect the production of red blood cells. Anemia can be caused by a slight shortening of the normal survival of red blood cells.
If the cells are small, we speak of microcytic anemia; if they are large, it is called macrocyte anemia; and if they are normal in size, it is called normocyte anemia. The diagnosis of anemia in humans is based on a hemoglobin less than 130 to 140 g / L (13 to 14 g / dL); in women, it is less than 120 to 130 g / L (12 to 13 g / dL). Additional tests are then necessary to determine the cause.
