I'm about a week post-op and whenever I go to the bathroom I feel faint and go to sleep for 30 minutes or an hour before then wake up in a rush to go. When it happens it is diarrhea and burns so badly. Is this normal or should I contact my doctor?

I haven’t heard anyone describe those exact symptoms yet. I would put a call in to your team.

Definitely worthwhile touching base with your surgeon. I wondered if it could be bile, so I googled and found this

Stomach acids, digestive enzymes, and bile

When food enters the stomach, acids and digestive enzymes attach themselves to it and begin breaking it down.

The digestive system adds bile to food when it passes through the small intestine. By the time food passes through, these acids and enzymes should no longer be acidic.

Diarrhea speeds up the digestion process, so foods often do not break down fully. This means that stomach acids, digestive enzymes, and bile may still be present in diarrhea. These can damage the tissues and cause a burning sensation in the rectum during or after a bowel movement.

So update us on how you are now. What was the cause? Are you okay now?
