Nausea, vomiting, drooling. What's going on?

1. Irrational diet: Patients eat a large amount of irritating food in a short time, resulting in gastrointestinal spasm, which may cause nausea, vomiting and salivation symptoms.

2. Indigestion: Patients eat too much and gastric contents press gastric mucosa and stomach wall, which may cause gastric motility disorder with nausea, vomiting and salivation symptoms. 3

. Gastroesophageal reflux: Esophageal mucosal barrier function weakened or clearance decreased, so that gastric contents reflux into the esophagus, due to esophageal mucosa stimulation, may lead to nausea, vomiting and salivation symptoms.
