Nausea one month post-op

I began getting nauseous and throwing up five to seven times a week in November of 2004. My family practioner diagnosed that it was my galbladder. I had an ultrasound which showed no stones. I had a pipida scan with a slightly lower than normal ejection fracture and a upper endoscopy with biopsy which showed mild gastritis. I had my galbladder removed in April of 2005. Since then I have not been getting sick as often but I am still throwing up 3-4 times a week. I never had any "galbladder attacks" with extreme pain. My only symptom was the nausea which has not gone away completely. Now I also have severe heartburn which was not present pre-surgery. I am confused at to what to do next. I am a 25 year old female. I have lost a total of 20 pounds which I did not need to lose. I now weigh under 100 pounds. If anyone has any idea what my next step could be please help! Tweet
