Hello and welcome to healthcare magic.
I am dr ASAD and I have read your question.i can understand your concerns.
Signs and symptoms of cholelithiasis(gall stones)include
Right upper abdominal quadrant pain.
Vomiting can occur because of severe pain.
Diarrhea occurs due to
malabsorption of fats due to insufficient or no bile reaching the
small intestine from gall bladder.
If i were your wife's treating physician i would have done her stool culture and sensitivity to look for any infective agent to rule out
gastroenteritis.i would have examined her to look for murphy's sign which is holding of breath in inspiration by the patient during palpation of of right upper quadrant.i would have prescribed nonsteroidal anti inflammatory drug such as diclofenac 75mg for pain.i would have prescribed intravenous fluids such as ringer lactate to replenish the fluids and electrolytes which she lost due to diarrhea and vomiting.serum lipase to rule out
pancreatitis.
Gall stones will nead surgical removal.
Laparoscopic cholecystectomy is minimally invasive pricedure with less post op marbidity.other option is open cholecystectomy..
I would suggest you to meet a general or hepatobilliary surgeon.
Thanks.
Hope the answer is helpful.
Furter querries will be appreciated.
