Anemia caused by a lack of vitamin B12 can be prevented through a well-balanced diet. B12 injections can prevent anemia after surgeries known to cause vitamin B12 deficiency.
- Eat a varied diet. Good sources of vitamin B12 are liver, fish and eggs.
- Because vitamin B12 is only found in food of animal origin, strict vegetarians should take vitamin B12 supplements to avoid deficiency.
- If a family member also suffers from pernicious anaemia extra care should be taken to prevent deficiency.
- Anyone who has undergone surgery in their small intestine or stomach should pay attention to any of the symptoms mentioned above.
