why am i salivating so much

Excessive salivation, also known as hypersalivation or sialorrhea, can happen for various reasons. Common causes include infections or cavities in the mouth, pregnancy, certain medications, gastroesophageal reflux disease (GERD), and nervous system disorders like Parkinson's disease or stroke. Other triggers can be dietary factors such as spicy or sweet foods, stress, anxiety, oral irritations, or dental problems. Sometimes, toxins or poisons and conditions affecting saliva clearance like jaw problems or neurological disorders can also be responsible. Treatment depends on identifying and addressing the underlying cause.
