Thyroid and B12
by bookbybook, Oct 09, 2007 09:58AM
I was diagnosed as Hypo in April '07. Have been on 75mcg Levothroid since then. I think I actually felt good of about 1 month since I've been on the meds, but now feel like I did before I ever started taking anything. My TSH showed in normal range after test in August, so I'm wondering if maybe the problem now is a B12 deficiency--I know sometimes the symptoms mimic each other. If I took a B12 supplement, would it do any good and how much should I take? At what point would I know that it's still a Thyroid problem and not a B12 problem? It takes about 2 months to get in to see my endocrinologist--should I just schedule an appt. and wait on the B12?
Thanks for your time........

Would ask to have the B12 tested first to see if it is low (<400 is borderline low and <200 is very low).
Target TSH is around 1.0. Some patients, but not all, may benefit from a combination of T4 (ie, levothroid) and T3 (ie cytomel).
Thyroid symptoms are non-specific so often people think they have thyroid symptoms but it is really something else. Most often it is not a medical problem, but an issue with balancing stress, diet, exercise, sleep etc -- look into that possibility as well.

a lot of people with thyroid probs have low levels of certain viatmins/minerals. You can take up to 1000mcg's of b-12 a day. Also vitamin d up to 1000 too.(sometimes prescription if that's not enough) See if you feel better after taking a cuuple of weeks. I also hear about low ferritin levels. All these things can be tested to see levels.
