Hi, my aunt is 52 years old and for about the last 10 years , I have noticed that she constantly spits into a paper towel or tissue. She also rinses her mouth with water, and spits into a bottle frequently. I already knew that she has ocds with germs and washing her hands, but could this be OCD related? Also, she told me she does this for her health, and gets upset when asked too much about it. She does not have mouth or teeth issues. Could this be psychological, physiological? Thank you Paul
