How Can Pernicious Anemia Be Prevented?
You can't prevent pernicious anemia due to a
lack of intrinsic factor. Without intrinsic
factor you won't be able to absorb vitamin B12
and will develop pernicious anemia.
Although uncommon, some people develop
pernicious anemia because they don't get
enough vitamin B12 in their diets. You can
take steps to prevent pernicious anemia due
to dietary factors.
Eating foods high in vitamin B12 can help
prevent low vitamin B12 levels. Good food
sources of vitamin B12 include:
- Meats such as beef, liver, and poultry
- Fish and shellfish
- Egg and dairy products, such as milk, yogurt, and cheese
- Breakfast cereals and other fortified foods that have vitamin B12 added
Vitamin B12 also is found in multivitamins and in B-complex
vitamin supplements. Doctors may recommend supplements for
people at risk for vitamin B12 deficiency, such as strict vegetarians or people who have had stomach surgery.
Older adults may have trouble absorbing vitamin B12. Thus,
doctors may recommend that older adults eat foods that
are fortified with vitamin B12 or take vitamin B12 supplements.
