Westernized diets and increased pollution exposure are among several factors accelerating rates of inflammatory bowel disease (IBD) worldwide among developing nations. As numbers swell, scientists urge health systems to prepare infrastructure and personnel.

I'm not claiming to be a wastewater expert by any means but by chance I know more than most people should about sanitary infrastructure.

I'm almost completely certain that we have not increased our code required number of bathrooms in a public area in a while and probably won't for a long time. So don't expect more bathrooms in public places (I'm sorry).

There's really no need for us to introduce more infrastructure over a slight increase in bathroom usage. Even if we all (meaning all of us get IPD) end up using the bathroom one or two more times per day there's so little impact on our wastewater infrastructure.

We use so much more water and produce so much more wastewater showering, doing dishes, and laundry than we do flushing toilets (like 6 to 1) and industries also supply a lot of wastewater. I'm much more well versed on infrastructure than biology but I'm assuming IBS doesn't produce a significant more waste just spreads it out and maybe waters it down a bit. While toilets certainly take the emphasis on what is sanitized at a wastewater treatment plant. What enters the plant mostly water and will leave the plant almost completely water and most of it isn't from toilets anyways.

The noticeable impact will come from aging infrastructure and increase in urban populations.

If we continue to separate rainwater from wastewater as most cities have and continue to switch fixtures from standard to low water use, we might see less wastewater in the most urban areas.
