Brief Answer:
Thyroid and calcium status must be optimized

Detailed Answer:
In which year approximately did you have total thyroidectomy for the hurthle cell cancer?

The reason I ask is , because the latest guidelines use the term 'presumed cured' at 5 years after surgery if certain criteria are met, after which higher-than-usual doses of thyroxine can be reverted to standard dose given to those without a recent history of thyroid cancer.

This is relevant because the post-thyroid cancer patients are given higher doses to keep the cancer in check. However this relatively higher dose can cause symptoms like weight loss and fatigue as you are reporting.

Secondly, it is important that your calcium levels are in the normal range for optimal health

Brief Answer:
You need labs

Detailed Answer:
The following blood tests are necessary

ionized calcium
phosphorus
intact PTH
25 hydroxy vitamin D
electrolytes, calcium and creatinine

Discuss the results with your endocrinologist and see if a medication called calcitriol is required to normalize your calcium levels.

Regarding thyroxine dose, you will be given relatively high-ish doses for at least 5 years, barring any sound medical reasons not to.

Hi...
Thankyou for your reply....I am only under the care of an ENT specialist....never seen or been referred to an endocrinologist.....
Do you think I should be referred...
Again I have been increased on my thyroxine from 175mcg to 200 mcg....
The amount seems to be rising not decreasing....
I'm getting very confused now....
