I am 70 y.o. and have hypothyroidism that seemed to get worse after stopping smoking. I am talking Synthroid .88 which was increased from .75 a few months ago. My recent TSH results were 3.3 and my doc says that's perfect. But I am still having symptoms. When I was smoking (stopped over a year ago) my TSH was usually 1.0. I don't understand why it got worse after quitting smoking. I don't know if my doc is afraid to change my meds because of my age or what. I know something isn't right because of symptoms. I asked him if he needs to test the adrenals and he just laughed. I know we slow down as we age but my problem is not from ordinary aging.
