Anemia is a condition where there is an abnormally low number of red blood cells circulating in the body. Anemia is a common blood disorder, affecting an estimated 3.4 million Americans. Anemia is not contagious, so you cannot catch it from someone who has it. Anemia, one of the more common blood disorders, occurs when the level of healthy red blood cells in the body becomes too low. Anemia can be temporary or long-term, and it can range from mild to severe. A common cause of anemia is not having enough iron. The recommended amount of iron you need each day increases during pregnancy from about 18 milligrams (mg) per day to 27 mg per day. Most pregnant women get this amount from a combination of eating foods that contain iron and taking a prenatal vitamin. Women and people with chronic diseases are at increased risk of the condition. Many forms of anemia exist, each with its own cause. Anemia, like a fever, is a symptom of disease that requires investigation to determine the underlying etiology. Often, practicing physicians overlook mild anemia. This is similar to failing to seek the etiology of a fever. Anemias can also be caused by such conditions as external bleeding, chronic disease, pregnancy, alcoholism, bleeding disorders, infection and hereditary conditions.
The symptoms of anemia may resemble other blood disorders or medical problems. Normocytic anemia usually starts slowly. It doesn't have many signs at first. Among many other causes, anemia can result from inherited disorders, nutritional problems (such as an iron or vitamin deficiency), infections, some kinds of cancer, or exposure to a drug or toxin. The three main classes of anemia include excessive blood loss (acutely such as a hemorrhage or chronically through low-volume loss), excessive blood cell destruction ( hemolysis ) or deficient red blood cell production (ineffective hematopoiesis ). Anemia is a condition where there is a lower than normal number of red blood cells in the blood, usually measured by a decrease in the amount of hemoglobin. Hemoglobin is the oxygen-carrying part of red blood cells. It gives these blood cells their red color. There are many different treatments for anemia, including increasing dietary intake of readily available iron and iron supplementation; the treatment is determined by the type of anemia that is diagnosed. In severe cases of anemia, a blood transfusion may be necessary.
