Causes 2
Chronic diarrhea can have many causes because it may result from disorders affecting digestion, absorption, or movement through the gastrointestinal tract. Possible causes include persistent infections, food intolerances such as lactose intolerance, medication effects, irritable bowel syndrome, inflammatory bowel diseases such as Crohn disease and ulcerative colitis, and other diseases affecting the stomach, small intestine, or colon. Previous gastrointestinal surgery can also contribute.
Infection
Inflammation
Risk Factors
Risk factors depend on the underlying cause. They may include exposure to contaminated food or water, use of medicines that can cause diarrhea, food intolerance, inflammatory or other chronic gastrointestinal disorders, and previous digestive tract surgery. A history of recurrent intestinal symptoms or diseases affecting nutrient absorption may also increase the likelihood of persistent diarrhea.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of chronic diarrhea begins with a detailed history of the duration, frequency, appearance, and triggers of bowel movements, together with a physical examination. Healthcare providers may use blood tests, stool studies, tests for infection or inflammation, and other investigations depending on the suspected cause. Additional testing such as imaging, endoscopy, or specialized tests may be required when symptoms persist or an underlying intestinal disorder is suspected.
Prevention
Key Prevention Tips
Prevention depends on the underlying cause
Good hand hygiene, safe food preparation, and drinking safe water can reduce infectious causes
Avoiding foods that consistently trigger symptoms and using medicines only as directed can help prevent some episodes
People with chronic gastrointestinal disorders should follow their treatment plan and seek medical advice for persistent diarrhea, dehydration, blood in the stool, unexplained weight loss, or other concerning symptoms
