Prayers, Please

Daddy has been sick since Thursday with what they thought was a stomach bug, but (without going into gory details) others symptoms made it clear that something else was going on, so after a CT scan, they sent him to the ER at one hospital then transported him by ambulance to another (where his surgeons are) for emergency surgery to resolve the blockage in his small intestine. However, when he got to the hospital, he stabilized and they decided to wait and see if it resolves itself (which apparently happens sometimes). I have lots of questions, but my main one was: do they know what is causing the blockage? The answer I got was that the majority of the time it is scar tissue from previous surgeries (which he likely has plenty of). So if anyone is still reading this, we appreciate your prayers. Daddy is being cared for well and is receiving fluids, but has had virtually no nutrition since Thurs. He's not in much pain but is very nauseous still. I will update tomorrow as we know more.
