I am a 76 year old male in generally very good health with mild Type 2 diabetes (fasting blood sugar around 135, A1C about 5.8, no medication used) and have recently (6mo) been experiencing very dry mouth when sleeping (upon waking).
I do not generally breathe through my mouth, though I do snore, but never experienced dry mouth before in my life.
I keep water available, but it only helps very briefly.
Upon waking and throughout the day I do not have any dry mouth, and have normal salivation as I always did.
I've had no changes in medication (I do suffer from mild hypertension and take lisinopril with HTCZ in the morning, but at the same dose I have for years before dry mouth).
I asked my PCP and he had not a clue, nor considered this significant, but I awake frequently during the night (true before dry mouth) and it's truly unpleasant to have the feeling my mouth is 'glued together' by a dry pallet.
No life or health changes I am aware of accompanying the onset of dry mouth.
Ae there any concerning aspects to this (a disease or condition), or should like my doctor suggested I just ignore it?
