Sialosis or sialadenosis refers to the hypertrophy of the parotid and salivary glands. It often occurs in bulimia nervosa patients after several days of cessation of self-induced vomiting. Though it typically goes away with continued cessation, it can also be treated through sour foods to induce salivation, heating pads, NSAIDs, and sometimes pilocarpine if other treatments are ineffective.
