I have had dry mouth after a possible exposure. At six months I had my last Elisa test and it was negative. The white toung and extremely dry month are still with me. Should I get re-tested? I saw and allergist in with he did some blood tests for allergies, but nothing reacated. What else could this be? Is it possible I am infected, but have not seroconverted?

Whereas dry mouth is a common condition in people who have HIV disease, there are many other conditions, medications, and circumstances, that can lead someone to present with dry mouth. For instance, stress alone can cause dry mouth as can the over 500 medications that list xerostomia (dry mouth) as a side effect. There are conditions effecting the salivary glands such as Sjogren's syndrome, salivary gland stones, etc., which have nothing to do with HIV infection that can manifest as severe dry mouth.

Maybe the best way to address your concerns are as follows: I would not consider dry mouth alone a sign or symptom of HIV infection since there are so many other potential causes for this condition.

I hope this help!
