Persistent Vomiting & Hiccups: Possible Causes & What to Do

Question
I was in class about four days ago when all of the sudden i just felt like i had to puke. That was like 4 days ago, but when i throw up its usually white foam! I puke at least 4 times a day and i seem to be getting these hiccupps over and over. Thy aren't hard hiccupps just the regular kind, but i am vomiting up WHITE FOAM! Do you have ANY CLUE what this could be?

Answer
It is hard to say without exam but would require some lab tests including exclusion of ovarian pituitary functions tests and pregnancy. If those are negative would require motility studies of the esophagus, gallbladder studies, and neurological studies.
I am sure you have tried a clear liquid diet for a day to see if that will settle it
