Chen Long has encountered many patients who suffered from neurological symptoms due to lack of B12, such as poor memory, acupuncture on hands and feet, impaired vision, and deterioration of taste and smell. In addition, B12 deficiency may also lead to broken mouth, dry mouth, and bitter mouth. Therefore, if you don’t want to eat, it will be more difficult to replenish nutrients, forming a vicious circle.
Nutritionist Gao Minmin said that vegetarians are more likely to be deficient in vitamin B12 than meat eaters, because most of the sources of B12 are animal foods, such as meat, animal offal, egg yolks, milk, etc. Especially vegan patients should pay more attention Supplement with vitamin B12.

Chen Long added that the general blood test usually does not include the B12 concentration, but if the blood cell volume is found to be large and there are suspected symptoms, such as numbness in the hands and feet but normal glycosylated hemoglobin, it means that the nerve is not caused by diabetes. disease; or feeling tired but excluding liver function problems, then a strong suspicion of B12 deficiency may be necessary.
