You could experience ANY of the hypothyroid symptoms....wow I could never imagine missing a whole weeks worth of medicine. I keep mine right on my bathroom sink so I can take it the minute I get up in the morning.
It can become a very serious life threatening situation for you not to take your thyroid meds....I dont think I would let that happen again.
Sure can, especially if you have Hashimotos. What were your most recent lab results? Did you have the antibody tests done? How about your free t3 and free t4 tests? All have to be done in order to get a full look at what is going on. Hope you feel better! :)
