Hypo after subtotal Thyroidectomy?

Hi Everyone

Im a 31 year old male. I Had a subtotal thyroidectomy (right lobe and part of the left was removed)on Aug 6,2010 due to toxic nodule/endonome.I experienced hyperthyroidism symptoms before the surgery.What I would like to know is,after the surgery,is my thyroid(or what is left of it)now underactive(hypo)?

Some days I feel OK but other days,like today, I feel totally drained,sluggish ,lightheaded,dizzy,no energy and sometimes some nausea.

My doctor started me 10 days after the surgery on Euthyrox(Levothyroxine) 50.He said that I must use these 10 days to get rid of the excess hormone caused by the hyperthyroidism.After 6 weeks from surgery I need to return to him with blood tests and he said he will then determine the right dosage of medcine I need.

Is this typical symptoms Im having after surgery and can Hypo symptoms occur so early after surgery and is this in fact Hypo symptoms Im experiencing?

Any information is appreciated !

Thanks

its not that easy in many cases to just get balanced as quick as one would hope.

Yes - then to rid the excess hormone ( off the hot nodule) with free flowing hormone still present - that now makes sense.. and even more reason why the trial dose - low amount - is being implemented right now.

To seriously save yourself "time".... I can strongly suggest to research and talk here to others about how important the free level test are in order to bouce back quickly from these type of condtions. You most likely will be hypothyroid after things simmer down from the active responses you had with that nodule and now that this is removed.... eventually you will fall hypo to a degree.


The whole thing balancing this with meds can be challenging and knowing it and your body is critical for you.

Hi Stella5349

Thanks for your comment! Regarding the excess thyroid hormone,I meant to say that the doctor said because of the hyper symptoms I had, my thyroid ''overproduced'' hormone.So, after the surgery I had to wait 10 days to get rid of the ''excess'' hormone before starting the Euthyrox medicine.So I started using the medicine 10 days after the surgery.

I was not tested for autoimmune thyroid prior to the removal.

I personally think the dosage might be to little in my case , as I feel horrible some times and other days I feel OK. Maybe Im just impatient and should give this thing a while to get sorted out.It is just sad that everything was OK 3-4 months ago and all of a sudden this ''disease'' hits me. Thanks for your support and to this forum. I have learned a lot as I'm am so new to this.

I just hope and pray this will get sorted out a.s.a.p

With the removal of part of the gland ( which had present , a hyper-active nodule) then removing that portion of the gland toxic should bring you to a hypothyroid condition.

... unless the half left in - can function completely on its own which is unlikely in most cases.)

Were you testing for autoimmune thyroid prior to the removal?

With removing most of the function now you will need to find the right balance after this surgery - which could take sometime. Your doctor started you on a trial dose of T4 medication which is common to see where labs will be at and then adjust them accordingly in phases.


Euthyrox(Levothyroxine) 50 - will not rid any "excess" thyroid hormone. I am not sure if you may have misunderstood or if this doctor is misleading. This is a T4 medication that will actually put back into the system the T4 hormone in order to convert it to a T3 hormone, that the body needs to be well.
