I have had Crohn;s disease since 2004 and have had a really rough time. In short, my disease has never been in remission and I am only 25. I have severe ulceration in the sigmoid as well as the rectum. The disase is very hard on me each day but the past two days I have a new symptom. My mouth is salivating I have no idea what is causing it or how to make it stop. I am on a list of medications but have been for a long time (nothing new added). My question is: What causes heavy saliva production and how can I prevent this? Is it dangerous?
