What Are the Main Causes of Chronic Loose or Watery Stools?
Many people experience frequent loose or unformed stools, a condition directly linked to one’s physical health. It may result from improper diet or serve as a symptom of an underlying disease. So, what causes persistently unformed stools and frequent diarrhea? Let’s explore the possible reasons.
Causes of Persistently Unformed Stools and Frequent Diarrhea
1. Enteritis
Bacterial infection in the gastrointestinal tract can trigger inflammation (enteritis), leading to unformed stools and diarrhea—primarily due to damage to the intestinal lining.
2. Indigestion
Irregular eating habits—for example, frequently skipping meals—can over time impair digestive function and result in unformed stools.

3. Age-related factors
As people age, bodily functions gradually decline—including digestive capacity—and immune defenses weaken. When pathogens invade the gastrointestinal tract, they may cause persistent unformed stools and diarrhea.
4. Consumption of irritant foods
Frequent intake of spicy, greasy, or otherwise irritating foods can stimulate the gastrointestinal tract, resulting in unformed stools and diarrhea. Maintaining a balanced diet rich in nutritious, easily digestible foods helps prevent such symptoms.
5. Intestinal tumors
One potential sign of intestinal tumors is chronically unformed stools; severe cases may involve recurrent diarrhea and even bloody stools. Such symptoms warrant immediate medical evaluation to rule out malignancy.

The above outlines common causes of persistently unformed stools and frequent diarrhea. If you experience these symptoms, over-the-counter digestive aids (e.g., Jianwei Xiaoshi Pian) may provide temporary relief, but dietary adjustments—such as avoiding irritants—are essential. Most importantly, consult a healthcare provider for thorough evaluation and targeted treatment. We hope this information proves helpful.
