Dear Tarasgrace,
You haven't mentioned your age. But if you are around 40 years and have family history of
menopause at around this age, then you might be perimenopausal as of now and that's the reason for your disturbing hot flushes and missed periods.
High sugars can be another reason for feeling restless but hot flushes is not how a full blown
diabetes presents generally.
History of surgical removal of thyroid warrants two things- if your thyroid state normal as per tests done within last 3 months? If yes, then fine. otherwise get them done.
Secondly after a few years post
thyroidectomy most of the people tend to suffer from something called 'hypoparathyroidism' where your body calcium drops down and you get these symptoms.
hence get your OGTT,
HbA1c, Serum calcium, Phosporus,
Albumin, ALP, TSH, FT4, FSH, LH done. Do revert back for further questions. Good luck.
