My 15 month old son had an orchiopexy yesterday today he has had frequent loose stools could it be a side effect of general anesthesia?

See below . Whereas nausea and vomiting are quite common after general anesthesia, diarrhea is not. If diarrhea does not improve or worsens; or is associated with fever, lack of appetite, inability to take oral fluids, signs of dehydration, persistent crying or irritability, I would recommend you both notify the surgeon and contact your child's pediatrician for advice and recommendations. .
