Some shit must have gone down at this pool

When they get caught doing the thing they shouldn't be doing in the pool

That was my question. Do you have to provide your medical records every time you want to go swimming

My post below goes into more detail. They can’t really know or confirm. The sign is for you. If you know you’ve had diarrhea recently or actively and you swim- you’re putting other people at health risk- and believe it or not to some diarrhea can be a very serious or fatal risk. You don’t need to actually poop on the poop or even have poop for the microorganisms responsible to be present in your GI tract still and spread to the water where even with chemical treatment they can survive several days and infect others. So the sign is more a firmly worded request that you be considerate of others who use the poop and not put them at risk.

They won’t. You know, and swimming with recent or active diarrhea puts others at health risk, and for some potentially serious risk of even death in the extreme cases. The microorganisms associated with diarrhea can survive after you no longer have symptoms, they get in the poop water when you swim and can survive even heavily treated pool water for several days. It’s one of the most common causes of illness from swimming. They’re basically asking you to think of other people and not put them at risk. If you don’t say anything or make it super obvious you have the trots they aren’t going to lab test you- but you’ve been made aware that what you are doing is wrong and dangerous and against their wishes, and the hope is that you would be a decent human being in a shared public space and consider others.

I have IBS. I don't think I've gone 14 without diarrhea in 10 years....

IBD, Crohns, Colotis, a removed gal bladder, there are tons of medical causes for diarrhea not related to contamination and which those with the conditions may regularly or constantly experience diarrhea- especially those who may have had a GI re section. Now- I’ve never found a “conclusive” ruling on this- but the issue with diarrhea and swimming is when one has an illness where a virus, bacteria, parasite etc. causes it. Most GI conditions the diarrhea is not caused primarily by a contaminant that can be transmitted, but through inflammation and mechanical means.

Now- diarrhea and loose stool are obviously easier to “slip”- little out unknowingly or on accident, and more readily make their way into water than solid stool- so I’ve heard an arguable case that there is still a slightly higher risk of General fecal contamination- but a key to keep in mind with a GI condition is that GI disorder diarrhea isn’t caused by a transmitable pathogen. Of course- one who frequently has diarrhea and pain might be less likely to notice when an actual organism is causing it. So there are still risks but the best sources I can find tell me that people with GI issues aren’t banned from pools for fear of harming others.

In fact- swimming tends to be good for people with GI issues. It’s low impact exercise and often helps manage symptoms and health.
