For what reason you thyroid was removed? What are the medication you are taking?
when were your last thyroid function tests done? How old are you?
My thyroid was removed because it was huge. It was not growing like a goiter. It grew inside to the back of my neck. I had the thyroid tests done about 2 months ago. I take 200 mcg levothroxine a day. I took synthroid for years previous until they changed it to the new levothroixine. I am 50 years old. I still have my ovaries and have never experienced this before.
With your past history of thyroidectomy, a reassessment of the thyroid function tests are mandatory as these can fluctuate suddenly and may be responsible for the hot flashes. The other causes associated with the hot flashes are (they can appear anytime);
1) higher body mass index
2) higher follicle-stimulating hormone levels
3) lower high-density lipoprotein cholesterol levels
4) vaginal dryness
5) trouble sleeping
It has been found by various studies that serum IL-8 concentrations (blood work) in premenopausal, perimenopausal, and postmenopausal women with hot flashes are significantly higher than those in women without hot flushes. IL-8 may be associated with peripheral vasodilation in women with hot flashes.
There is a medication called as Gabapentin, which does help in hot flashes.
