Stool pH is dependent in part on fermentation of sugars. Colonic fermentation of normal amounts of carbohydrate sugars and production of fatty acids accounts for the normally slightly acidic pH. If disaccharide intolerance is suspect, simple tests may be performed. Slightly alkaline pH may occur in cases of secretory diarrhea without food intake, colitis, villous adenoma, and possibly with antibiotic usage (with resultant impaired colonic fermentation). A stool pH of <6 (measured by pH paper) is suggestive evidence of sugar malabsorption. Children and some adults notice that their stools have a sickly sweet smell as the result of volatile fatty acids and the presence of undigested lactose. Low stool pH also contributes to the excoriation of perianal skin which frequently accompanies the diarrhea.
No special preparation is needed for Ph Automated Stool. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing Ph Automated Stool. Your doctor depending on your condition will give specific instructions.
