ist reis glutenfrei — when to see a doctor?

Rice is naturally gluten-free, as it does not contain gluten proteins. However, cross-contamination can occur in processed rice products (e.g., seasoned rice mixes, ready meals) or in facilities that also handle wheat. If you experience persistent digestive issues (bloating, diarrhea, abdominal pain) or fatigue despite eating only rice and other gluten-free foods, you should see a doctor. Possible causes include undiagnosed celiac disease, non-celiac gluten sensitivity, or other conditions like irritable bowel syndrome. A physician can perform serological tests (tissue transglutaminase antibodies) and, if needed, an intestinal biopsy to confirm or rule out celiac disease. Important: You must be consuming gluten for these tests to be accurate. Self-diagnosis or elimination diets without medical guidance can lead to false negatives and nutritional deficiencies. The evidence here is based on clinical practice and consensus guidelines, not on genetic or biomarker data from consumer tests.
