Stool is generally slightly alkaline (basic), though the pH can vary.
Here's a more detailed breakdown:
-
Typical pH: The pH of human feces is variable but typically falls on the alkaline side. An average pH for a healthy individual is around 6.6, suggesting a tendency toward a slightly alkaline state.
-
Factors Affecting Stool pH: Several factors can influence whether stool is more acidic or basic:
-
Diet: What you eat significantly impacts stool pH. Diets high in fiber can lead to the production of short-chain fatty acids, which can make the stool more acidic.
-
Gut Bacteria: The balance of bacteria in your gut plays a crucial role. Certain bacteria produce acidic byproducts, while others produce alkaline byproducts. An imbalance can shift the overall pH. An overgrowth of acid-producing bacteria (like lactic acid bacteria) can result in more acidic stool.
-
Digestive Issues: Certain digestive problems can alter stool pH. For example, lactose intolerance can lead to more acidic stools due to the undigested lactose fermenting in the gut. Infections like E. coli or rotavirus can also cause acidic stools.

When Acidic Stool Might Indicate a Problem: While stool pH can vary, consistently acidic stools may indicate:
- Lactose intolerance
- An infection (e.g., E. coli, rotavirus)
- Overgrowth of acid-producing bacteria
-
In Summary: While generally slightly alkaline, stool pH can fluctuate based on diet, gut bacteria, and underlying health conditions.
