<s>[INST] I have had recent weight loss fatigue and extreme vomiting on and off for the past 6 months.  I have been seen in the ER several times with no diagnosis blood tests and x-rays result in no diagnosis other than it must be the flu. I have had my gal bladder remove a year ago and the symptoms are similar to the gal bladder attacks i have had in the past. When i vomit it looks like slime no blood and the stomach pain is severe, no lose stools.  This happens about every three weeks and lasts about a week the symptoms clear up but i still feel nauseous until the vomiting begins again. I can eat very little at any given time and am tired all the time. [/INST] HiYour description of the condition points to a diagnosis of Gastric malignancy or severe peptic ulcer disease or its complication, though its not confirmatory unless test results comes. If i would be your treating physician/Surgeon i would suggest you to haveUpper G I EndoscopyFecal occult blood testUSG abdomenFew other routine investigations.Instead of visiting ER i would suggest you to visit a gastro enterologist on a OPD basis which can solve your issue.Hope you find my information useful.Any further questions are appreciated.Thanking youDr Samir </s>
