Something strange that people, and myself, have observed in diving is that being submerged in water tend to turn off nausea and abdominal pain. The theory is a combination of mammalian diving reflex and pressure will inform the body to focus on respiration and blood flow, in favor of other lesser emergencies. With personal experience with malfunctioning digestive tract, I discussed this with a researcher and it was also something he had heard from other patients.
Obviously it doesn't fix the underlying issue, and it add some risk to the diving itself, but the temporary break from symptoms are something I value a lot.
