Gut problems? Get it checked out guys

[Damn]

Just wanted to put this out there. Guys who are experiencing gut problems from pfs (most of us I think) need to follow up on that. I got an endoscopy and colonoscopy done today because of my pfs related gut issues and weight loss. They removed quite a few polyps in my bowel which is not normal for someone my age. These can become cancerous if not found early so it's a good thing they did.

Not 100% that this started from pfs, but I wouldn't doubt it.

Question for BD or anyone else who has done this...what product did you use for the colon cleanse before your procedure and did you notice any affect on your gut microbiome? I am considering getting a colonoscopy due to my age (over 50) and have concerns about this. I have been working hard for over a year to rebuild/balance my gut and don't want to take something that will f it up again. I found a number of studies, but none with subjects who were likely already in a compromised state.
