What are common symptoms of celiac disease?

Celiac disease is an autoimmune condition that primarily affects the small intestine in response to the ingestion of gluten, a protein found in wheat, barley, and rye. Common symptoms of celiac disease include diarrhea and fatigue due to malabsorption of nutrients, which is a direct result of intestinal damage caused by the immune response to gluten. Diarrhea occurs as the body struggles to absorb nutrients and manage inflammation in the small intestine, often leading to digestive distress. Fatigue is frequently reported as individuals with celiac disease may not receive the necessary nutrients, leading to deficiencies that contribute to feelings of exhaustion.

In contrast, the other symptoms listed in the options are not typical indicators of celiac disease. For instance, excess saliva and weight gain are generally not associated with this condition. Shortness of breath and rash can arise from various causes, but they are not hallmark signs of celiac disease. Lastly, frequent headaches and dizziness may have many potential underlying causes, and while they can occur in individuals with gluten-related disorders, they are not primary symptoms of celiac disease itself. Understanding the specific symptoms associated with celiac disease is crucial for accurate diagnosis and management.
