Common Causes of Chronic Diarrhea

Chronic diarrhea is generally defined as having loose or unformed stools that occur more frequently and persist for more than four weeks. There are several underlying reasons that can contribute to this condition.

Gastrointestinal Disorders

One of the primary causes of chronic diarrhea is related to gastrointestinal diseases. Conditions such as intestinal tuberculosis, inflammatory bowel disease (IBD), colon cancer, intestinal parasites, and neuroendocrine tumors of the gastrointestinal tract can all disrupt normal digestive function and lead to prolonged diarrhea.

Systemic Diseases

In addition to digestive tract issues, certain systemic illnesses can also cause chronic diarrhea. For example, hyperthyroidism increases metabolism and can speed up bowel movements. Similarly, diabetes may affect nerve function in the digestive system, leading to irregularities in bowel habits. Liver and biliary tract diseases can also interfere with nutrient absorption and digestion, contributing to persistent diarrhea.

Understanding these potential causes is essential for identifying the correct treatment and managing symptoms effectively. If you experience ongoing digestive issues, it's important to consult a healthcare professional for an accurate diagnosis.
