How this protocol works
In plain language
Celiac disease is an autoimmune condition where eating gluten (a protein in wheat, barley, and rye) causes damage to the small intestine. This damage impairs nutrient absorption, leading to multiple deficiencies. The only treatment is a strict, lifelong gluten-free diet.
CRITICAL: The primary treatment for celiac disease is a strict gluten-free diet. Supplements address the nutritional deficiencies but cannot replace dietary management.
COMMON DEFICIENCIES in celiac disease:
- Iron (most common - causes anemia)
- Vitamin D (affects bones)
- Calcium (affects bones)
- Vitamin B12 and Folate (affect blood and nerves)
- Zinc (affects immunity and taste)
- Magnesium
- Fat-soluble vitamins (A, D, E, K)
WHY DEFICIENCIES OCCUR:
The small intestine (especially the duodenum and jejunum) is where most nutrients are absorbed. Gluten-induced damage to the intestinal lining means vitamins and minerals cannot be properly absorbed.
IMPORTANT NOTES:
- Many supplements contain gluten as a binder - always verify gluten-free status
- Some medications contain gluten - check with your pharmacist
- Get regular lab work to monitor nutrient levels
- Bone density testing is recommended
Iron* deficiency is extremely common and may be the first sign of celiac disease. Sometimes IV iron is needed because oral iron is poorly absorbed.
Vitamin D and Calcium* are essential because celiac patients have significantly higher osteoporosis rates.
B12 and Folate* deficiencies can cause anemia and neurological problems.
Probiotics* may support gut healing and are being studied for celiac disease.
Expected timeline: With a strict gluten-free diet, intestinal healing begins within weeks and is often complete within 1-2 years. Nutritional deficiencies typically improve within 6-12 months of dietary adherence.
