Hypersalivation - Definition


Hypersalivation, or ptyalism, is excessive salivation due to overactive saliva glands. The cause can be pain, Zenker's diverticulum, ulcer, pregnancy, infectious lesion in the mouth, or cancer. Chronic hypersalivation can be caused by Parkinson's disease, stress, neurological trauma, or even rabies. This condition can also frequently be observed in the elderly who exhibit repetitive tongue movement.
