I have been on a low dose of levo (25mcg) for a couple of months now and I am expecting a dose increase next week when I see GP. Tsh 4.16 (0.30-5.50) at recent test, no T4 provided on printout. In april it was tsh 5.8 and t4 12.3 (11.5_22.7). My queery is I often feel dizzy while moving about, this can be quickly resolved by eating or drinking something sweet. I am encouraged to eat less and move more. Can anything be inferred by this?
