                        Thyroid hormone output is at its lowest an hour or two after going to sleep.  Thus the early sign of thyroid deficiency can be hypoglycaemia at this time.  Thyroid hormone tests , flat glucose tolerance test, can help in deciding whether thyroid hormone adminstration could lead to undisturbed sleep and improved health generally.     Remember this  even if you do not act on it immediately.  Best wishes, E.R. Blay.
