<s>[INST] I am concerned because my daughter is having symptoms of gall bladder problems, however I noticed that it stated you could become sick 2 to 3 hours after a meal but she is getting sick as soon as she finishes eating.  This evening she had pizza and had no more finished her second piece when she started feeling bad and went to the bathroom and vomited.  Twice it has been when eating pizza and the 3rd time was eating a fatty food.  This has hit within the last two weeks, could the vomiting hit her that fast? [/INST] HI thanks for using Chat Doctor. Your Q> Could the vomiting hit her that fast? Yes. Since she has problem with gall bladder. Our body start responding from the time food is in mouth and related enzymes starts secreting and synthesizing and the organs like gall bladder starts contracting to release related digestive enzymes. The gall bladder symptoms occur more often with fatty food, so better to reduce it. You have not mentioned what problem she has(diagnosis). Better to consult your doctor for proper management as there is cure for gall bladder problem. Better to prevent any complication than treating them. Hope I answered your question. Wish you good health. Take care. Regards Chat Doctor.  </s>
