Vitamin B12 deficiency anemia is a blood problem that occurs when there is not enough of this vitamin in the body. Vitamin B12 (also called cobalamin) helps make red blood cells . Red blood cells travel throughout the body carrying oxygen to the cells and removing wastes. Without enough vitamin B12, your body won't produce enough red blood cells and your cells won't get the oxygen they need.

You will normally get enough vitamin B12 if you eat a varied diet that includes animal products such as milk, cheese, and eggs. People who follow a vegan diet can prevent vitamin B12 deficiency anemia by eating foods fortified with this vitamin or by taking vitamin B12 supplements or multivitamins. Babies born to women who eat a vegan diet are at increased risk for developing this type of anemia. They should be checked by a doctor to see whether they need vitamin B12 supplements.

Vitamin B12 deficiency anemia usually develops when your body cannot absorb this vitamin from food. This can happen if:1, 2 You have pernicious anemia. In pernicious anemia, your body destroys the cells in your stomach needed to help your body absorb vitamin B12. You have had surgery to remove part of your stomach or the last section of your small intestine (ileum ).

Your doctor will do a physical exam and ask questions about your medical history and symptoms. You will also have blood tests, such as: Complete blood count (CBC). This test gives important information about the kinds and numbers of cells in the blood. Having a low red blood cell count is a sign of anemia. Methylmalonic acid and homocysteine tests. The amount of these substances in the blood rises as the level of vitamin B12 decreases. Vitamin B12 and folic acid tests.

If your vitamin B12 deficiency anemia is mild, you may not have symptoms or you may not notice them. Some people may think they are just the result of growing older. Symptoms develop slowly over years, as the amount of vitamin B12 absorbed by the body decreases and the vitamin B12 stored in your body is used up. Low levels of vitamin B12 cause damage to the brain and nerve cells. The symptoms this causes may be the first ones you notice.

Deficiency of vitamin B12 refers to the less-than-required levels of vitamin in the body. Cynocobalamin is needed for the formation of RBCs that carries oxygen; hence, deficiency of it may lead to anemia later followed by dementia. That leads to weakening and tiredness. It may also result in gastrointestinal disorders, neural tube defects, cancer, cardiovascular diseases, Alzheimer's disorder, depression etc.

Because plants don't produce vitamin B12, the uninformed commonly suggest meat as a source of the vitamin. However, B12 is actually not a chemical compound, it's a microbe — a bacteria that thrives in soil, not in digestive tracts. Animal flesh is therefore not an original source of the vitamin. B12 is co-incidentally found in beef, for instance, because cattle ingest the microbe when they graze in fields or eat unwashed feed.

The data on B12 is still coming in, so it is impossible to say "It's no problem....", however, the latest information suggests that acquiring enough B12 is not as problematic as it was once thought. If you are concerned about inadequate B12, there are many foods which are fortified with B12, in addition to vitamin pills. Here is the most recent information: From the book: Simply Vegan: Quick Vegetarian Meals, by Debra Wasserman and Nutrition Section by Reed Mangels, Ph.D., R.D.

Common signs and symptoms of Vitamin B12 deficiency include fatigue, weakness, faulty digestion, nausea, loss of menstruation, numbness nervousness, diarrhea, striking behavioral changes, paranoia, hyperactive reflexes, fever, frequent upper respiratory infections, impaired memory, infertility, sore tongue, low platelet count and increased bleeding, neutropenia etc.

Iron is an essential part of hemoglobin, and without enough hemoglobin, anemia develops and the body does not get the right amount of oxygen. Iron deficiency anemia develops after the body has had a low level of iron for a long time, either because of iron loss or inadequate iron intake over a long period of time. It can be caused by blood loss, not taking in or absorbing enough iron, increased demands for iron (like pregenancy or rapid growth).

Vitamin-A deficiency is a serious condition that can lead to blindness and increase susceptibility to infectious agents. It affects an estimated 200 million people, primarily in developing countries where rice is a dietary staple. Using biotechnology techniques, scientists have developed a new strain of rice, called golden rice, that naturally produces beta-carotene, the precursor to vitamin A.

Vitamin B12 (cyanocobalamin), folic acid, and vitamin B6 have been shown to be important nutrients in the maintenance of normal homocysteine levels. Abnormal homocysteine levels are considered to be a risk factor for heart disease. Vitamin B12 requires a protein secreted by the stomach for proper absorption and utilization. However, due to increased intakes of certain medications (ie.

Vitamin B12 (cyanocobalamin), in combination with B vitamins folic acid and vitamin B6, have been shown to be important nutrients in the maintenance of normal homocysteine levels. Abnormal homocysteine levels are considered to be a risk factor for heart disease. Vitamin B12 requires a protein secreted by the stomach for proper absorption and utilisation. However, due to increased intakes of certain medications (ie.

Folic acid deficiency anemia results from lower-than-normal levels of folic acid in the body. Your body needs folic acid, one of the B vitamins, to produce red blood cells . The human body does not produce enough folic acid to meet its needs, so your diet should include foods high in folic acid, such as citrus fruits, leafy green vegetables, and fortified cereals.1 Your body can store enough folic acid to last 2 to 6 months. However, anemia can develop within weeks of a shortage of folic acid.

When a person doesn't have enough iron, it can lead to a condition known as iron-deficiency anemia. Although iron deficiency has long been considered the major cause of anemia in childhood, it's become much less common in the United States over the past 30 years, primarily due to iron-fortified infant formulas and cereals. The body needs iron to make hemoglobin. If not enough iron is available, hemoglobin production is limited, which in turns affects the production of red blood cells.

the turn of the century, vitamin D deficiency led to an epidemic of rickets (softening of the bones) in U.S. urban centers. We solved the vitamin D deficiency largely through the fortification of foods. However, this fortification proved to be too much as peanut butter, hot dogs, soda, bread, and even beer were fortified with vitamin D. Excessive amounts of vitamin D also were added to some milk products, causing toxic amounts of vitamin D to reach infants and young children.

Golden Rice alone is not expected to solve the problem, but its use could significantly reduce the incidence of the VAD syndrome. Rice provides as much 80 percent or more of the daily caloric intake of 3 billion people—half the world's population. Many eat little else than rice. But other challenges such as poverty, lack of infrastructure and lack of education remain and should be dealt with by governments and policymakers.
