colorpHast pH-indicator strips
Stool pH less than 5.5 is indicative of carbohydrate absorption abnormality. Low stool pH also contributes to excoriation of perianal skin as commonly seen with profuse diarrhea. Slightly alkaline pH may occur in cases of secretory diarrhea without food intake, colitis, villous adenoma, and possibly with antibiotic usage. High stool pH may be associated with colorectal cancer.
