Does anyone have b12 and thyroid issues? Over the years my thyroid has been boarder line and when I got it tested a few weeks ago my doctor said it was normal 4.57 (range 0.35-5.5) I always feel rough and convinced it isn't just the b12 deficiency that's making me feel this way 😩 My auntie has an under active thyroid but the GP wasn't interested in that! The only thing they picked up on was that my cholesterol was higher than the range so they've booked me in with the nurse to discuss how to change my lifestyle! I would like to point out I'm a mum to three children and weight 9 stone. I don't seem to put weight on or lose it always seem to stay the same!
