[|Human|] hi im a 18 years old boy who got regular college to do. so everyday o wake up as usual. but sometimes it happens that i feel like vomitting after i brush my teeth. its only feel, i dont do it. but yes often i theow up some liquids. since in morning my stomach remains empty i had nothing to throw out. after i wash out these liquids and drink some water. my mouth feels like i ate sugar-mixed water. that means the portions beside my teeth inside my mouth becomes sweet after the vomitting liquid washes the place up. sometimes i feel like i threw up enzymes or something when i had nothing in my stomach. after a while this becomes ok too. i thought i should consult a doc. to be noted i wake late at nights someday and always have to get up at 6:30am. Id like to know whats going on. sorry for spelling mistakes. i woke up a few minutes ago and experienced this again. altho no liquids even today. completely dry.
[|AI|]  Thanks for your query, I have gone through your query. Some people vomit or feel like vomiting when they brush their teeth. This is because the toothbrush that contact with the back part of the oral cavity. This, in turn, activates a persons gag reflex, thus causing the person to instinctively throw up. When the bristles contact the soft palate you will feel like vomiting. Nothing to worry, while brushing you need to be sure of not contacting or stimulating the palatal mucosa with the brush. I hope my answer will help you, take care.
