Hello Nikkim,
Since all my experience has been with diarrhea caused by ulcerative colitis, I can't give you a correct answer.The conditions causing each case may be different.However,the insoluble fiber in fresh vegetables did work for my stool formation.I think the diet is worth a try.Start out by eating smaller amounts of fresh vegetables and then increasing each day.This gives your colon a chance to adapt.I would give it a least a week or more.No fruit.You colon will give you the correct answer.Metamucul is soluble fiber.Try going without it temporarily.Use a probiotic.Additional information at google.com Type diarrhea in the search window. sheldon
