Some of this could be accountable from the gases used to inflate your abdomen during surgery, some could be down to inflammation from the actual procedure itself… If you haven’t moved your bowels since surgery this also can cause tummy bloat…. So if you haven’t ‘been’. you could try some prune juice and make sure you are drinking enough fluids. You could also speak to your local pharmacist who may advise some stool softeners or glycerin suppositories to get things moving depending on your symptoms. Always worth mentioning it to your dietitian too as they can assess your diet and help advise regarding this.
