Learn why it feels like your brain is coming out of your mouth during vomiting and understand what actually happens in your body during this process.
It's a common expression to say "my brain is coming out of my mouth" when vomiting, but scientifically, your brain never actually leaves your body through your mouth.
Vomiting is the process where your stomach contents are forcefully expelled through the mouth. The brain plays a critical role in initiating this process by sending signals to the stomach muscles to contract and push the contents out. However, your brain remains safely protected inside your skull throughout this process.
If you ever feel extremely dizzy, disoriented, or confused during vomiting, it's a sign that the brain is affected by the illness causing the vomiting, but it still stays inside your head.
In summary, the brain doesn’t go out of your mouth. The sensation might feel intense because radiation of signals and muscular contractions occur, but physiologically, your brain always stays safely inside your skull.
