Experiencing watery poop occasionally is a common occurrence, often linked to what we’ve recently eaten. These instances are usually triggered by dietary choices, infections, or food poisoning.
Some individuals might also suffer from acute diarrhea, characterized by loose and watery stools lasting up to 14 days. Let’s delve into the common reasons behind watery stool.
Dietary Factors Leading to Watery Stool
Certain foods, beverages, and supplements can increase the likelihood of experiencing watery stool or diarrhea. This often happens when the small intestine struggles to efficiently process large amounts of certain sugars.
For instance, sugar alcohols, prevalent in many fruits, vegetables, and artificial sweeteners, can act as a laxative. Poor sugar digestion can lead to increased pressure and water accumulation in the colon, resulting in watery bowel movements.
Diets rich in lactose, a sugar found in dairy products, can also contribute to watery stools. When lactose isn’t properly absorbed by the small intestine, it can ferment in the gut microbiota, causing diarrhea, abdominal discomfort, and bloating. It’s estimated that around 36% of people in the United States experience lactose malabsorption.
Watery stools can also be triggered by diets high in:
Infections and Food Poisoning as Causes of Watery Poop
Viruses, bacteria, or parasites can cause inflammation in the stomach and intestines. This inflammation disrupts normal bowel function, often leading to watery stools.
Viral infections are the most frequent culprits behind watery stools and acute diarrhea. Norovirus, for example, is responsible for a significant percentage of foodborne illnesses in the United States, affecting millions annually. Rotavirus and viral gastroenteritis are also common viruses that can induce symptoms like watery diarrhea.
Bacterial infections are another significant cause of foodborne illnesses and can result in watery stools. Common bacteria involved include:
- Salmonella
- Campylobacter
- Shigella
- Escherichia coli (E. coli)
- Clostridium difficile
