B12 Deficiency


I am looking for some answers, I have had Hashimotos hypothyroid for 15 years without any issues.
I was feeling shakey (shaky), dizzy, fatigued, eyes are bothering me, they feel jumpy, heart palps and muscle pain. My blood test came back showing TSH .09.  They lowered my synthyroid.  I was also told I was slightly anemic 10.8.  B12 was low 212 and  Vit D 26

My dr told me I just need to take a multi vitamin.  I have been reading up on b12 deficiencies and requested my dr give me a b12 injection.  She told me it was not necessary.  Can someone provide some feedback.  I am seeing a neurologist next week to rule things out but I feel B12 could be causing alot of these issues along with being hyerthyroid.

Thanks, Deb

Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.

Without the ability to obtain a history from you and examine you, I cannot comment on a formal diagnosis or treatment plan for your symptoms. However, I will try to provide you with some information regarding this matter.

Your B12 level is normal, but low normal.  Usually symptoms of B12 deficiency manifest themselves as neuropathic pain (pain and tingling), difficulty feeling vibration and difficulty walking.  It can sometimes affect memory and also cause you to be irritable.  It does not usually manifest with the symptoms you have—which are usually suggestive of a hyper thyroid.

B12 deficiency can cause Anemia, and could be the cause of yours, however other causes should be ruled out too.

I would also recommend being further tested to see why your B12 is low.  There are autoimmune causes which prevent the absorption of B12 in your stomach.  I suggest you be checked for this.  

Hope this information was helpful.
