I had a total thyroidectomy in August 07 three months later I was told that I had had thyroid cancer, needless to say it threw me completely, now my problem is my weight, I eat less than 2000 calories a day, exercise thee times a week, more if I can make the time, yet my weight is 18 stone (252 lbs) I am 5'10 ". I'm puzzled by this, as my dosage of eltroxin is 225mg x6 days and 200 x 1 day I also am being treated for high cholesterol and reflux meds Crestor 5mg daily and Nexium 20mg daily both of which can do damage to the liver
How are they treating the cancer---are you using tsh suppression to reduce the chances of a recurrence? Usually with a tsh kept below .1 (Us ranges) your levels shouldn't be at the rate that would make you gain. Most thyroid cancer patients do not have weight issues. You may need a higher dose. Ask about tsh suppression, and also get your other levels--free t3 and free t2 tested.
What is your tsh? What are your blood levels? What was your thyroglobulin levels? Are they required to tell you these things in your country? This is how your medication should be adjusted based upon those things, as well as your blood pressure, etc.
Here in the US, we can go to special hospitals such as one that specializes in cancer, to get better care as well as education on these things. Here in the us we use synthroid or tirosent, and a high dose of synthroid would be let's say 275--300 MCG (not uncommon if someone were a large male I suppose) as opposed to MGs, so I have no idea what your type of dose means. If you were on 225 mcg that would be a normal dose for a male, if it were 225mg---I would assume that would be an extremely high dose? If it's mcg, you could increase.
You don't seem very heavy to me, but you want to make sure it isn't water weight, which is more of a sign of under-medication. I think knowing your blood levels could help you better understand what's going on.
my TSH is 0.7
T4 free 30.7
I also have Ocular Graves disease which means I can't have Radio Iodine treatment. The thyroid was totally removed and their reasons to supress the TSH is incase there are any rogue cells still there that the TSH could feed. All I know is that it gets me down, a side affect of a high dose of eltroxin is anxiety and depression which I've experienced .
