[Non-celiac disease non-wheat allergy wheat sensitivity]

Area of Science:

• Gastroenterology
• Immunology
• Dietary Science

Context:

• Non-celiac wheat sensitivity (NCWS) is a condition distinct from celiac disease and wheat allergy.
• Diagnosis relies on symptom improvement with a gluten-free diet after excluding other conditions.
• Estimated prevalence ranges from 0.5% to 6% globally.

Purpose:

• To summarize the current understanding of non-celiac wheat sensitivity.
• To highlight diagnostic challenges and potential triggers.
• To emphasize the need for further research into underlying mechanisms.

Summary:

• NCWS presents with gastrointestinal issues (bloating, pain, diarrhea, nausea) and extraintestinal symptoms (fatigue, headache, joint pain) post-wheat consumption.
• No specific biomarkers or intestinal mucosal damage are identified.
• Potential triggers include gluten, other wheat proteins, amylase-trypsin inhibitors, and short-chain carbohydrates.

Impact:

• NCWS diagnosis and management remain challenging due to the lack of validated biomarkers.
• Understanding the role of the gut microbiome is crucial for future therapeutic strategies.
• Further research is needed to elucidate the pathophysiology and develop accurate diagnostic tools.
