Many types of anemia exist, such as iron-deficiency anemia, pernicious anemia, aplastic anemia, and hemo- lytic anemia. The different types of anemia are linked to various diseases and conditions. Anemia can affect people of all ages, races, and ethnici- ties.
How long does physiological anemia last?
Birth to three months – The most common cause of anemia in young infants is "physiologic anemia," which occurs at approximately six to nine weeks of age. Erythropoiesis decreases dramatically after birth as a result of increased tissue oxygenation and a reduced production of erythropoietin [3,4].
What is physiologic anemia in newborn?
In healthy term infants, clinical signs or symptoms of anemia are absent; this normal decline in Hb is referred to as “physiologic” or “early anemia of infancy.” Among term infants, Hb values fall from 14.6 to 22.5 g/dL (146 to 225 g/L) at birth to a low of 10.0 to 12.0 g/dL (100 to 120 g/L) by 8 to 10 weeks of age.

WHO guideline for anemia in pregnancy?
Center of Disease Control (CDC) defines anemia as pregnancy hemoglobin less than 11 g/dl (Hematocrit;{Hct} < 33%) in the first and third trimester and less than 10.5 g/dl (Hct < 32%) in the second trimester while World Health Organisation (WHO) defines anemia in pregnancy as Hb values less than 11gm/dl [3, 4].
Is anemia common in early pregnancy?
Mild anemia is normal during pregnancy due to an increase in blood volume. More severe anemia, however, can put your baby at higher risk for anemia later in infancy.
How is anemia treated during pregnancy?
Anemia during pregnancy can easily be treated by adding iron or vitamin supplements to your daily routine. Typically, this is all that is needed to reverse the effects of anemia. However, in very rare cases, women with severe anemia may need a blood transfusion.
What is the physiologic anemia of infancy?
Several factors appear to be involved. With the onset of respiration at birth, considerably more oxygen becomes available for binding to hemoglobin, and , as a consequence, the hemoglobin-oxygen saturation increases from 50% to 95% or more.
What happens to the hemoglobin level when there is no erythropoiesis?
Because there is no erythropoiesis, aged RBCs that are removed from the circulation are not replaced and the hemoglobin level decreases.
When does hemoglobin drop?
Normally, this point is reached between 8 and 12 wk of age , when the hemoglobin concentration is about 11 g/dL. At this juncture, EPO production increases and erythropoiesis resumes.
Is there a hematologic problem with prematurity?
There is no hematologic problem, and no therapy is required. Premature infants also develop a physiologic anemia, known as physiologic anemia of prematurity. The hemoglobin decline is both more extreme and more rapid.
What causes aplastic anemia?
Causes of aplastic anemia include infections, certain medicines, autoimmune diseases and exposure to toxic chemicals. Anemias associated with bone marrow disease. A variety of diseases, such as leukemia and myelofibrosis, can cause anemia by affecting blood production in your bone marrow.
How to prevent anemia?
Treatments for anemia range from taking supplements to undergoing medical procedures. You might be able to prevent some types of anemia by eating a healthy, varied diet.
How to avoid iron deficiency anemia?
But you can avoid iron deficiency anemia and vitamin deficiency anemias by eating a diet that includes a variety of vitamins and minerals, including: Iron. Iron-rich foods include beef and other meats, beans, lentils, iron-fortified cereals, dark green leafy vegetables, and dried fruit. Folate.
What causes low red blood cells?
Vitamin deficiency anemia. Besides iron, your body needs folate and vitamin B-12 to produce enough healthy red blood cells. A diet lacking in these and other key nutrients can cause decreased red blood cell production. Some people who consume enough B-12 aren't able to absorb the vitamin. This can lead to vitamin deficiency anemia, also known as pernicious anemia.
What is the best vitamin for red blood cells?
Besides iron, your body needs folate and vitamin B-12 to produce enough healthy red blood cells. A diet lacking in these and other key nutrients can cause decreased red blood cell production. Also, some people who consume enough B-12 aren't able to absorb the vitamin.
Why do pregnant women have anemia?
Your bone marrow needs iron to make hemoglobin. Without adequate iron, your body can't produce enough hemoglobin for red blood cells. Without iron supplementation , this type of anemia occurs in many pregnant women.
What causes blood loss in the stomach?
It is also caused by blood loss, such as from heavy menstrual bleeding, an ulcer, cancer and regular use of some over-the-counter pain relievers, especially aspirin, which can cause inflammation of the stomach lining resulting in blood loss. Vitamin deficiency anemia.
What are the symptoms of anemia?
Several signs and symptoms occur in all types of anemia, such as fatigue, shortness of breath and feeling cold. Others include:
Why is anemia genetic?
This genetic form of anemia happens because the shape of the red blood cells is faulty. They are sickle shaped, which means that they can clog the blood vessels and cause damage. The hemoglobin does not work correctly. This type of anemia is most often, but not always, found in African Americans.
Why do we need iron?
Your body needs a certain amount of iron to make hemoglobin, the substance that moves oxygen throughout your body. However, iron-deficiency anemia is just one type. Other types are caused by: Diets lacking in vitamin B12, or you can’t use or absorb Vitamin B12 (like pernicious anemia).
Why is it important to have iron in your diet?
It is important for children to have enough iron and other nutrients in their diets to prevent anemia and the related problems with lack of attention, delayed development of motor skills and problems with learning. In older children, you need to pay more attention to signs of anemia during growth spurts and menstrual cycles.
What happens when you don't have enough red blood cells?
Anemia happens when you do not have enough red blood cells. The cells travel with iron and hemoglobin, which is a protein that helps carry oxygen through the bloodstream to your organs all through the body. When someone develops anemia, they are said to be "anemic.".
Why are my red blood cells low?
Red blood cell levels are low due to one of the following reasons: Your body cannot make enough hemoglobin ( low hemoglobin ). Your body makes hemoglobin, but the hemoglobin doesn't work correctly.
How do you know if you are lacking iron?
Other signs that you might be lacking in iron include having brittle or spoon-shaped nails and possible hair loss. You might find that your sense of taste has changed, or you might experience ringing in your ears.

Can B12 cause anemia?
ANS: B. Effects on the nervous system can occur if a vitamin B12 deficiency causes the anemia. Myelin degeneration may occur with the resultant loss of fibers in the spinal cord, producing paresthesia (numbness), gait disturbances, extreme weakness, spasticity, and. reflex abnormalities.
