Thyroid problems after surgery?

I am 7 months post op and have had a slew of problems, but most recently it has been with dizziness.....my pcp did lab work and an EKG and halter monitor, one lab test was for thyroid. Mine came back abnormal and high. I can't have any tests done for one week because of the vitamins that I have to stop taking for the next week.  Just wondering if anyone else has had this come up?

I assume they will figure it out with the tests, so the only thing I can offer is to make SURE you are hydrated. When I hear dizzy/tired, that is the first thing I think of, and getting dehydrated seems too common in newer post ops.
