I have had loose stools bordering on diahrrea for about two weeks. I started a new protein shake called visalus and it has something in it called 'non digestive malodextrin' or something like that. COuld that be the cause. I'm also eating a ton of raw veggies, so a high fiber diet. Pls help - i'm a runner and I had a long run this past saturday - it was terrible. I had no energy at all. I have been drinking a ton of water too, so I am not sure...can you get dehydrated if you're drinking a lot of water? Also, can a super-high fiber diet result in an intestinal blockage and if so, like if you have an intestinal blockage does that mean you don't go at all or can you have diarrea along side it?
