“Can anesthesia lead to gastric troubles?”

It's very unlikely that anesthesia drugs would cause a chronic physical gastric ailment. The most probable cause may be the actual surgery itself.

Typically, no. However, opiate medications can cause constipation-type problems or nausea.

It is certainly possible that a general anesthetic could cause disruption of normal digestive function. Without knowing your history and the type of surgery, it is only speculation. Many other factors may have contributed such as medications given, administration or antibiotics, pain medication, positioning during surgery, the type of surgery, disruption of feeding and
diet, and the location of the surgery. Chances are that there may be multiple reasons for this change. You may want to consult your surgeon and/or anesthesiologist if you are concerned.
