More saliva protects your oesophagus, throat and mouth from your stomach acids. Stomach acids are strong enough to burn your hand so they’re more than enough to damage more sensitive parts. If you know who Steve-O of the Jackass cast is, his voice sounds quite raspy because of the damage to his vocal chords and a condition called Barrett’s oesophagus caused by excess vomiting.
