yes.
before I was diagnosed hypothyroidic.
my TSH reached 'lethal' heights before I could get any 'doctor' to do anything about it.
I strongly advise you to get a 'full panel' thyroid test done.
I still suffer with congestive heart failure because (partly)_ this went almost three years befire any healthcare practitioner did the right test.
I'd gained 55 lbs.
and at one point - was eating less than 500 calories per day trying to stop the gaining.
but I didn't/couldn't keep that up very long before other symptoms started 'going off' because of the thyroid.
now, two years later - I'm finally getting the weight off.
but the thyroid had to be made right first. and that takes a long time.
I hope you'll consider getting tested.
I was miserably sick before it was found.
