Stomach pain while riding

Spanx while riding are enough to give you stomach issues! It's akin to wearing compression garments. Wearing regular spandex shorts would be much less compressive! Especially, cycling shorts with a wide, flat waistband.
I have GI issues while riding at times and I know that if I were wearing Spanx, it would definitely make it worse.

I had to look up what Spanx was. I'd still suggest that bib shorts might be worth a try. TE has some well priced Canari shorts, as does RoadID (from Giordana).

I get this after riding a few hours on a road trip in the car. I think it is related to the actual muscles in my stomach - like you, I have a tough time standing up straight without pain after a long ride or sitting in the car, but once I stretch out, it's okay. Pilates helps. I think when we're on the bike, in combination with all the other things our stomach is doing (digesting, our pelvic muscles dealing with the bladder, etc.) the stomach muscle contract or something... and cramp. I cut the elastic on my bike shorts and that helps a lot.

just one more thought. Are you swallowing air as you breathe? Would be uber great to ride with someone who could observe your riding. I also would chime in on the type of food and drink. I can't eat any types of protein bars and can only drink 2 electrolyte supplements and sometimes they will bother me as well.
