If you are not reading Mary Shomon's blog on thyroid disease, be sure to add it to your reading list (remember, thyroid is a hormone too!)
Mary republished a good article that needs to be heeded in this hot weather.......be careful about exposing your medications (especially your thyroid medications) to excessive heat in the summer. Even leaving your purse/tote bag/suitcase in a hot car can adversely affect the potency of your meds. I keep my car super air conditioned in the summer, partly because I carry around my bottle of progesterone cream to dose when I am out and about, and I don't want it turning into an ugly, runny mess! I am careful with my T3 thyroid med too, I carry several pills with me in my purse so that I can take my afternoon dose on time (my Levoxyl doesn't go in my purse unless I am travelling, as I only take that in the morning). As always, talk to your doctor (or better yet, your pharmacist, s/he probably knows more about it than the physician) about protecting your medications against the summer heat.
Don't forget in this weather, too, to stay hydrated! I now just automatically carry a water bottle with me wherever I go (and yes, I know at our age this means sometimes having to find a bathroom!), but I would rather not get dehydrated, the inconvenience of an extra bathroom trip is more than worth it.
