I, too, had horrible night sweats which have resolved after going gluten-free. I would wake up completely soaked, wet hair, sheets, and all. I guess that anything auto-immune (Celiac) can cause night sweats.
I have had night sweats, and I'm only 31. You are probably not menopausal, but gluten sensitivity can cause some adrenal and/or hormonal imbalances. These have very gradually ceased since I went gluten-free.
DavidB, I also was diagnosed with adrenal insufficiency. Sometimes I feel lightheaded when going from laying down to standing. Yes- it is possibly...
I've had this happen to. Also, when I lay down at night after eating, I can hear my head throbbing on the pillow- like my heart is beating in my head- does that happen to anyone?
