Does anyone else feel really nauseous immediately before/after going to the toilet?

I've noticed that I can get extremely nauseous right before I poop or immediately afterwards, I feel very sick for a good hour before it gradually fades.

Does anyone else have this? Feel like I'm suffering just for having basic body functions...

Edit: I didn't realise so many of you would agree. I'm so sorry we are all having to deal with this, but at least we are not alone. Keep strong and look after yourself!
