So you're not actively EMTing now? Too bad, we need more good EMTs.And yeah, you could eat nothing but bananas constantly and wouldn't be able to actually get hyperkalemic. The father of a family friend was stuck in the jungle with no supply waiting for a boat home from the Philippines at the end of WWII, and he and his buddies had nothing to eat but bananas for something like two weeks. They did all get diarrhea, but other than that they were fine.
I'm pretty sure that if you're healthy (no kidney problems), your kidneys will deal with the excess potassium. If you are unwell (say, massively dehydrated, or some other renal issue), your kidneys may not excrete the extra potassium, causing the hyperkalemia.
