So again today on my long run, I ended up nauseous and with diarrhea afterward. This has been an ongoing thing for weeks, but only after my long run (not my other runs). I've been careful about what I eat the day before (not much fiber, spicey food, etc.). Is it possible that the intestines get more upset on a long run because it's 2-3 hours of running which diverts blood flow from the intestines and to the legs?
I know this may seem crazy but try taking a powder fiber supplement 2x a day (morning and night). I take it before my long runs in the am and before bed. Seriously, I had major problems with this....and I went to a GI specialist and this is what he told me to do. I thought he was crazy but it worked and has worked for several of my friends too.
Check your water intake. I have no problems on runs up to 12 miles because I don't take any water. On long runs I try harder to "hydrate" effectively and too much water irritates my colon. Not fun. Just sipping a few gulps of water would be OK, but if you only stop once on a 20 miler it's not enough water. Gotta find a balance.
My advice would be to write down everything you eat & drink for a couple weeks. Match up when the diarrhea hits on the run/after the run and see if something can be adjusted. This time of year, it could be the warmer weather and lack of proper hydration, or you could actually be drinking too much gatorade or something sweet which irritates your stomach after your run. In the summer, I carry handheld 20oz bottles with neopryne handle - 1/4 gatorade/ 3/4 water mix, taking small sips thru my long runs.
I advise writing down everything you eat/drink because it worked for me. I developed lactose intolerance in my mid 30's. Long runs became shitty problems for months. During my yearly visit, my GP advised me to write down what I ate. Turns out, ice cream before bedtime, while a high calorie treat I had been having for years with no issue, was the problem. VERY clear with hindsight, but it took writing down my diet to fix my problem.
While not a problem for me, I have heard that some runners have a LACK of fiber problem, and add metamucil to their diet and have had success. My 2 cents...
Diarrhea cha cha cha, Diarrhea cha cha cha.....
could be lactose intolerance too.
