Results of two national surveys in the United States, the National Health and Nutrition Examination Survey (NHANES III-1988-94) and the Continuing Survey of Food Intakes by Individuals (CSFII 1994-9six) found that most children and adults in the US consume recommended amounts of vitamin B12. A deficiency may still occur as a result of an inability to absorb vitamin B12 from food and in strict vegetarians who do not consume any foods that come from animals.
As a general rule, most individuals who develop a vitamin B12 deficiency have an underlying stomach or intestinal disorder that limits the absorption of vitamin B. Sometimes the only symptom of these intestinal disorders is subtly reduced cognitive function resulting from early vitamin B deficiency. Anemia and dementia follow later.
Many of these symptoms are very general and can result from a variety of medical conditions other than vitamin B12 deficiency. It is important to have a physician evaluate these symptoms so that appropriate medical care can be given.
Create pregnant and you may/or lactating females you prefer a lot more vitamin B12?
During pregnancy, nutrients travel from mother to fetus through the placenta. Vitamin B12, like other nutrients, is transferred across the placenta during pregnancy. Breast-fed infants receive their nutrition, including vitamin B12, through breast milk. Vitamin B12 deficiency in infants is rare but can occur as a result of maternal insufficiency. For example, breast-fed infants of women who follow strict vegetarian diets have very limited reserves of vitamin B12 and can develop a vitamin B12 deficiency within months of birth. This is of particular concern because undetected and untreated vitamin B12 deficiency in infants can result in permanent neurologic damage. Consequences of such neurologic damage are severe and can be irreversible. Mothers who follow a strict vegetarian diet should consult with a pediatrician regarding appropriate use of vitamin B12 supplements for their infants and children. They should also discuss with their personal physician their own need for vitamin B12 supplements.
Just who else when you look at the B12 enhance to stop lack?
Individuals with pernicious anemia or with gastrointestinal disorders in B12 supplement. Older adults and vegetarians in B12 supplement or an increased intake of foods fortified with vitamin B12. Some medications in B12. Chronic use of those medications in B12.
people who have pernicious anemia
Anemia is a condition that occurs when there is insufficient hemoglobin in red blood cells to carry oxygen to cells and tissuesmon signs and symptoms of anemia include fatigue and weakness. Anemia can result from a variety of medical problems, including deficiencies of vitamin B12, vitamin B6, folic acid and iron. Pernicious incontrare ragazze coreane anemia is the name given more than a century ago to describe the then-fatal vitamin B12 deficiency anemia that results from severe gastric atrophy, a condition that prevents gastric cells from secreting intrinsic factor. Intrinsic factor is a substance normally present in the stomach. Vitamin B12 must bind with intrinsic factor before it can be absorbed and used by your body. An absence of intrinsic factor prevents normal absorption of vitamin B12 and results in pernicious anemia.
Most individuals with pernicious anemia need parenteral (deep subcutaneous) injections of vitamin B12 as initial therapy to replenish depleted body stores of vitamin B12. Vitamin B12 body stores can then be managed by a daily oral supplement of vitamin B12. A physician will manage the treatment required to maintain the vitamin B12 status of individuals with pernicious anemia.
individuals with gastrointestinal conditions
Individuals with stomach and small intestine disorders in B12 from food to maintain healthy body stores. Intestinal disorders that in B12 include:
the elderly
Hydrochloric acid helps release vitamin B12 from the protein in food. This must occur before vitamin B12 binds with intrinsic factor and is absorbed in your intestines. Atrophic gastritis, which is an inflammation of the stomach, decreases the secretion of gastric juices, including hydrochloric acid. Less hydrochloric acid in B12 separated from proteins in foods and can result in poor absorption of vitamin B12. Decreased hydrochloric acid secretion also results in growth of normal bacteria in the small intestine. The bacteria in B12 for their own use, further contributing to a vitamin B12 deficiency.
