Which symptom may indicate the presence of celiac disease?

Diarrhea after eating gluten is a classic symptom indicative of celiac disease. This autoimmune disorder occurs in genetically predisposed individuals and is triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. Upon ingesting gluten, individuals with celiac disease may experience gastrointestinal symptoms due to an immune reaction that damages the intestinal lining. This damage leads to malabsorption of nutrients and consequently can cause diarrhea, bloating, and other digestive issues.

In contrast, while severe headaches, blurry vision, and chest pain can occur in a variety of conditions, they are not hallmark symptoms of celiac disease. The primary and most consistent symptoms relate specifically to gastrointestinal disturbances, particularly in relation to gluten consumption. Understanding the key symptoms associated with celiac disease is essential for prompt diagnosis and management of the condition.
