Hiya Mary
Remember your op was a biggie. In order to get to your reproductive organs, the surgeon needs to take your bowels and bladder out to get to them, and when he's finished, they just get thrown back in, so to speak!
This can cause kinks, twists, loops etc in the intestines, they've been mauled about and need time to settle and find their own way back round where they were!
Hope that makes sense!
It's only been 5 weeks, so you need more time to recover, I was off work for 6 months after mine and I remember all the pain, gas, gurgling, bubbling, cramps like it was yesterday!
Speak to your gynae if you're worried, not the gastro.
take care
