Chronic dry mouth

Over the past few weeks I've noticed decreasing saliva and a dry mouth much worse than the temporary condition I experienced after RAI. Since my meds haven't changed in 4 or 5 months I'm wondering what would be causing this.

It just occurred to me that the contrast used in my scans might be the cause. I've had bi-monthly scans now going on about 6 months so I've had a lot more contrast than at any time in the past.

Can contrast cause this and, if so, does it go away when the scans are reduced or stopped?

Re: Chronic dry mouth

I don't know if the scans and contrast do this or not but one thing that can cause a chronic dry mouth is an autoimmune disease called Sjogren's . There are antibodies that can be tested for it.

There are also many medications that have anticholenergic effects so check to see if you are taking any of them.

Re: Chronic dry mouth

Hi Archie!

If it's not a side effect of your meds, it could be that your salivary glands were attacked by the rai (this happened to me a year after my RAI!)

They can come back, in the meantime, massage them (they are under your ear, along the jaw line) and drink a lot (even during the night) to keep up flow.

Re: Chronic dry mouth

Thanks for the replies. I'll have to do some research on the Sjogrens, Javelina. It's a long shot but certainly a possibility.

If contrast isn't the cause it's more likely a result of the two RAI ablations I've had, as Reese suggests.

I'm hoping others who have been given large amounts of contrast due to frequent scans will chime in.
