Gluten sensitivity vs celiac

{{whyLabel}}: Accurate data helps your doctor distinguish between autoimmune reactions and general sensitivities.

{{howLabel}}:

• Use a dedicated notebook or a free app like 'MySymptoms' to log everything you eat.
• Note the timing and severity of symptoms like bloating, brain fog, joint pain, or fatigue.
• Record 'extra-intestinal' symptoms (headaches, skin rashes), which are more common in gluten sensitivity.

{{doneWhenLabel}}: You have a 14-day log ready to present to a medical professional.

{{whyLabel}}: Testing for celiac disease requires the presence of antibodies; stopping gluten too early causes false negatives.

{{howLabel}}:

• Consume the equivalent of at least 2 slices of wheat-based bread daily.
• Do NOT start a gluten-free diet until all medical tests (blood and biopsy) are completed.
• If you are already gluten-free, consult your doctor about a 'gluten challenge' (typically 3-10g of gluten daily for 6-8 weeks).

{{doneWhenLabel}}: You have consistently consumed gluten for at least 6 weeks leading up to your test date.

{{whyLabel}}: This is the first-line screening tool to detect the autoimmune response characteristic of Celiac Disease.

{{howLabel}}:

• Request a 'tTG-IgA' (Tissue Transglutaminase) test and a 'Total IgA' test to ensure you aren't IgA deficient.
• If you have an IgA deficiency, ask for 'Deamidated Gliadin Peptide (DGP) IgG' testing instead.
• Ensure you are still eating gluten on the day of the draw.

{{doneWhenLabel}}: Blood sample is collected and sent to the lab.

{{whyLabel}}: A biopsy of the small intestine remains the gold standard for confirming the villous atrophy found in Celiac Disease.

{{howLabel}}:

• Discuss the 2025 ESsCD guidelines, which may allow a 'no-biopsy' diagnosis if your tTG-IgA levels are >10x the normal limit.
• If a biopsy is needed, ensure the doctor takes at least 4-6 samples from the duodenum and bulb.
• This step is vital to rule out permanent intestinal damage.

{{doneWhenLabel}}: You have received a pathology report confirming or ruling out intestinal damage.

{{whyLabel}}: Genetic testing can rule out Celiac Disease with over 99% certainty if the results are negative.

{{howLabel}}:

• Request a test for the HLA-DQ2 and HLA-DQ8 genes.
• Use this specifically if your blood tests or biopsies are ambiguous or if you are already on a gluten-free diet and cannot tolerate a gluten challenge.
• Note: A positive result only shows risk, not active disease.

{{doneWhenLabel}}: You have your genetic profile results in hand.

{{whyLabel}}: Since there are no biomarkers for NCGS, it is a 'diagnosis of exclusion' confirmed by symptom improvement.

{{howLabel}}:

• Only begin this AFTER all Celiac medical tests are finished.
• Remove all sources of wheat, barley, rye, and contaminated oats.
• Continue tracking symptoms to see if they resolve within 2-4 weeks.

{{doneWhenLabel}}: You have completed 28 days of 100% gluten-free eating.

{{whyLabel}}: Expert knowledge helps you understand the systemic nature of these conditions beyond just 'stomach aches'.

{{howLabel}}:

• Focus on the chapters regarding the difference between autoimmune responses and sensitivities.
• Take notes on the long-term health implications of undiagnosed Celiac vs. NCGS.
• Use the '2020 or later' updated editions for current medical context.

{{doneWhenLabel}}: You have finished the core chapters on diagnosis and management.

{{whyLabel}}: Gluten is often hidden in additives like malt, modified food starch, or soy sauce.

{{howLabel}}:

• Practice for 21 days: Scan every single ingredient list before a product enters your cart.
• Look for the 'Certified Gluten-Free' seal for the highest safety standard.
• Learn to identify hidden terms like 'Triticale', 'Seitan', or 'Brewer's Yeast'.

{{doneWhenLabel}}: You instinctively check labels for every purchase for 3 consecutive weeks.

{{whyLabel}}: For Celiac patients, even microscopic amounts of gluten (20ppm) can trigger an immune response.

{{howLabel}}:

• Replace porous kitchen tools like wooden spoons or scratched plastic cutting boards if they were used for gluten.
• Clean your toaster or buy a dedicated 'GF-only' toaster.
• Label shared condiments (butter, jam) to prevent 'double-dipping' with crumb-contaminated knives.

{{doneWhenLabel}}: Your kitchen has a designated 'Safe Zone' for gluten-free preparation.
