I am 2 weeks post-op: gastric sleeve. About four days ago my mouth started to be constantly dry. No matter how much water I drink. A little concerned.

Hmmm, interesting. I don't remember that happening, but I remember it for a few days after surgery from the anesthesia, etc.

Yes, I developed dry mouth after surgery. I still get it occasionally and I am 18 months post-WLS. My dentist recommended rinsing with Biotene every night before bedtime. You can also take Xylimelts which are tablets you place against your gums before you go to bed.

If your dry mouth continues, it's important to let your surgeon and dentist know so that they can make recommendations about how to best treat it. In some cases, medications taken after the surgery (but not necessarily related at all to WLS) can suddenly start causing dry mouth. Dry mouth can be somewhat dangerous because it causes tooth erosion and cavities, so definitely be proactive about it.

It's a common thing. I had that dry mouth for months. I sipped water continually. It finally went away, but was so annoying at the time.

I have a permanent dry mouth due to an auto-immune issue, if your dry mouth continues you may your doctor to check for sjogren's syndrome.

Nailed it above I was on meds for about 4 months for dry mouth.

Dry mouth is also a side affect of a low carb/high protein diet. I started getting dry mouth during my pre op when I went into ketosis. And a nasty taste. I have adjusted, biotene mouthwash is good, my husband uses it.
