Abstract
A comparison has been made of the fecal characteristics in controls and patients with the irritable bowel syndrome and diverticular disease. No detectable difference was found in the fecal wet weight, dry weight, or total bile acid excretion in the four groups. A significant increase in the percentage of the water content of the stool was seen in the idiopathic diarrhea group with irritable bowel syndrome. Significantly less magnesium, potassium, and calcium was found in the stools of patients with diverticular disease and a similar trend was noted in patients with the spastic colon. These changes did not relate to the age of the patients. This suggests a common etiology for these disorders. The presence of increased water and primary bile acids in the feces of patients with idiopathic diarrhea suggests that this is a separate entity.
