Stomach problems

[TheKatelynTv]

I am currently a 16 year old female. Recently I have started vomiting after everything I eat or drink, even water. Anywhere from 5 minutes to several hours after I eat I vomit up the entire contents of my stomach. If and when I am able to hold down foods I am miserable. I become dizzy and can almost feel the food in my throat. Physical activities are practically impossible to complete without extreme dizziness or vomiting. I have also experienced a abnormally large amount of gas. I am in no way pregnant, and am athletic. I am only 110lbs and 5ft 3. It has been going on for about a week. I am looking for any answers to what may be wrong with me. Thank you in advance!

No, I haven't been to a doctor yet. I was hoping that it would just be something that would go away.

Have you had an exam on your esophagus and stomach? Maybe you have the bacteria H.pylori.
