Involuntarily vomiting meals

Starting about mid December this year I came down with a stomach bug, or so I thought. I vomited on and off for about a week and then it went away. The last week of January I ended up in the emergency room having an appendectomy. I hoped that would stop my vomiting problems, but they have only gotten worse. After I eat I burp excessively. It's extremely embarrassing because I have absolutely no control over it. At first, I would only throw up 1 or two times a week but the past weekend I have thrown up everything I have eaten. The strangest thing is that there is absolutely no acidity to the vomit. The food I are is exactly what is thrown up. I've had blood tests but nothing showed up and I have an appointment the the gastroenterologist this week but I'm afraid they won't find anything. I should also say that I'm 18 years old and have never had any other health problems. Has anyone else had similar issues? And if so what were you diagnosed with? Tweet
