I've just been told my vit D level is 12 - but my GP says it only really needs to be treated if it's under 10! I told him I'd read some information from Barts (seen on someone else's response from Moggie) and anything under 30 is deficient (normal is 81-220). He said doctors were split on this and some incuding him believed anything under 10 was treatable but otherwise nothing really needs doing. However, he knew I wasn't happy so has prescribed me vit D and calcium and I'm going picking up the prescription tonight - he says I've got to take 3 a week for 12 weeks then have a blood test. Trouble is, on this website it also says that calcium together with vit D is prescribed for elderley patients in care homes yet my GP says he giving me both because of my age - 52. Don't know what they are yet and whether I should take them, but I'm feeling more and more unhappy with this GP's diagnosis. He reduced my levothyroxine from 175 to 100 at christmas - 'to experiment' as I had complained once again that I didn't think levothyroxine was treating me in the best way. He has just rang me on a telephone consultation to tell me I'm in the normal range and don't need my levothyroxine increasing and to stay on 100 mcgs a day - I wish I'd never gone to him and just stayed on the 175 a day as now I feel worse than I originally did and 1.5 stone heavier since xmas plus aching bones and muscle weakness (I've asked for the results and was told I could have a print out which I'm also picking up today) - I'll post these when I get them. It seems the more help I ask for help the worse it's getting?
