I've had this problem for a little while now. I'll burp and almost every other time, I'll vomit in my mouth a little bit. This keeps happening. It could be while I'm eating, or hours after. I'm not nauseous before usually, and I dont eat more than I can take. Whats happening and how can I stop it?
What you describe as "vomit in my mouth a little bit", is very likely to be a regurgitation, or return of undigested food back up the esophagus to the mouth, without the force and displeasure, and nausea associated with vomiting.
Belching and regurgitation are common symptoms of GERD.
Sometimes they can be associated with other stomach diseases, too.
