Could someone please find an article regarding this topic in Chinese for me?

I am looking for an informative and clear Chinese article talking about vitamin B12 deficiency as a side effect of taking Metformin (drug for diabetes) , as well as the short term symptoms and long term implications of it.

I'd like to show my mother this article so she can be more informed on her health.

Thank you.
