Gluten problem? Gluten intolerance (about 10% of people) may cause bloating, diarrhea, nonspecific complaints. Celiac disease, among its many manifestations may result in diarrhea. In the latter, exposure of intestine to gluten causes inflammation of affected gut lining, with a decrease in absorptive surface of that gut, & resulting malabsorption of food--best fixed by avoiding eating wheat, barley, rye.
Shouldn't. Unless you have celiac disease (also known as gluten enteropathy). What other symptoms do you have?
