I have diarrhea and constipation and both seem to be related to LC, and exacerbated by heat over a baseline around 73 F. Heat seems to throw my GI system into a frenzied freakout. This began in over a year ago and has not fully resolved. My GI specialist put me on supllements for mitochondrial health, as well as a stool softener, probiotics, magnesium and fiber. Either the cooler fall weather or the supplements have led to intermittent diarrhea and eliminated the bloating, cramping and pain, but hot days, or exertion in temperatures over that baseline will still set it off again.
