<s>[INST] my girlfriend is 27 yr old female who had her gallbladder removed 2 years ago...since then she experiences severe abdominal pain up under the lower ribcage accompanied by nausea and vomiting constantly for days on end...recent ultrasound came up normal.....ER physicians subscribe anti imflammatorys and a stronger version of an anti-nauseant - neither work. any suggestions? [/INST] Hello thank you for posting your query in Chat Doctor. I understand your concern. Let me make it clear to you about the gall bladder and its functions. Its stores' bile which is produced by liver, it transports to small intestine when after the food intake. When the gall bladder is removed, bile is no more stored, it is directly delivered to small intestine. Sometimes this bike may leak into stomach, causing irritation, pain, vomiting, loose motions. Rarely intestinal injuries during the surgery can cause abdominal pain, nausea, fever which needs immediate treatment. </s>
