What is a key symptom of celiac disease?

A key symptom of celiac disease is chronic diarrhea. This autoimmune disorder involves an inappropriate immune response to gluten, a protein found in wheat, barley, and rye. When individuals with celiac disease consume gluten, it causes an inflammatory reaction in the small intestine, leading to damage to the intestinal lining. This damage disrupts nutrient absorption and results in gastrointestinal symptoms, with chronic diarrhea being one of the most common and characteristic manifestations. Patients often experience loose, watery stools, abdominal cramps, and bloating, which can significantly impact their quality of life. Recognizing chronic diarrhea as a primary symptom is crucial for timely diagnosis and management of celiac disease to prevent further complications related to malnutrition and digestive health.
