Here in southeast lower Michigan, we have a week-long forecast of temps in the high 90s. That is extreme for my zone. But we are not the only region affected in this way. La Nina is responsible for higher temps everywhere this summer. I spend summers indoors with the A/C, as I am extremely sensitive to heat. I have multiple sclerosis, and heat makes my symptoms worse. So a summertime IBS flare feels like a double whammy. What about you? Does heat affect your IBS?
