That's good news.
I also have IBS confirmed from colonscopy, I was clearned of any IBD (chrons, uc) and also took a celiac test. I've had loose stools (not so much sticky) due to my poor diet of soda and high red meat intake.
What did doc say about the lipase. Years ago when I first found out my lipase test was elevated for no reason, I would test everyday using Quest Diagnostic, my numbers from M-Thurs (35, 42, 36, 138, 50, 70, 37) and cutoff ref range was 62, I believe.
One thing I did notice since I stopped marijuana smoke and went to vaping, my numbers were always low.
I wonder if your IBS with gut issues on top of tobacco smoke contributed to mid elevations of lipase. Also have you ever had an acute pancreatitis attack before in your life? Double down with pain, couldt eat for days, etc..? If not, you definietly do not have CP and pancreatic cancer is a no no. Once you have MRCP done, go celebrate because I know it will be clear.
