Hello. I am 3 weeks and two days post op. Overall my experience has been extremely positive.
I usually have an egg for breakfast but decided to switch it this morning. About an hour after having my usual coffee mixed with premier protein and a bit of low-fat milk and later 16 ounces of water , I had maybe 1/4 cup of oatmeal with milk with one strawberry and 5 slices of banana. Wow! It all went right through me VERY QUICKLY and straight to the toilet . It was traumatizing ! I can’t figure out if it was in the end too much milk or the oatmeal or maybe the banana ? All I know is I never want to experience that again ! Thankfully I was home. I can’t imagine experiencing that nightmare at work .
I have had diarrhea on and off since surgery but nothing this quick or overwhelming to my body .
Any thoughts or advice ?

It was sugar

add more fiber and avoid sugar (fruit)

You can test out fruit again in a few months

Ok definitely staying away from banana then ! Thanks .

They allow me 1/4 of a small banana at a time and no other fresh fruits. I've been too afraid to try them though.

That's it! I'm having some banana and strawberry tomorrow! No more straining for me!

I also had this response to sugar. It was from the sugar in a protein shake. It hit me after about 20-30 minutes and I was sick for hours. Cycles of diarrhea, dry heaves, then being very faint. I NEVER want to feel that bad again. It made a believer of me when it comes to sugar!!
