Hello, I am currently on dialysis for complete renal failure along with being diabetic. This is the second time that I have gone to go vomit while eating but at the time of the pressure from heaving it felt like my stomached was cramping up like as if the whole intestine was cramping or flipping inside out. It s a very immobilizing pain but it went away on its own and I vomited. Could this be an affect from a dialysis session?
