Gastric bypass with hiatal hernia repair done wed-off painkillers-vomiting (no nausea) a fecal like material-more coming out then going in-cause?

The fecal like: Material calls for visit to surgeon as soon as available, or go to er.

Call your surgeon: If more is common out than going in, you could become dangerously dehydrated. This is an urgent matter. Hope this helps!

See your surgeon: The cause could be something normal during the post-op healing from a bypass, but it could also represent a problem. If you are not able to keep yourself hydrated, then you need IV fluids and medical attention. I definitely recommend contacting your bariatric surgeon for further evaluation.
