Celiac Disease: The Effect on the Gut and Whole-Body Health

Celiac disease is more than a food intolerance — it’s an autoimmune disorder that, when triggered by gluten (found in wheat, barley, and rye), causes the immune system to attack the small intestine. This response damages the gut and can silently erode health over time. Dr. Colin Race explains:
Gut Damage and Malabsorption
The disease targets the villi — tiny projections in the small intestine essential for nutrient absorption. When gluten is consumed, these structures are damaged, resulting in malabsorption of nutrients like iron, calcium, vitamin D, B12, and folate.
Common and Hidden Symptoms
Classic digestive symptoms include:
– Chronic diarrhea or constipation
– Bloating and abdominal pain
– Weight loss
– Fatigue
– Nausea
But many experience non-digestive symptoms:
– Iron-deficiency anemia: Often the first noticeable issue.
– Bone weakness: Due to low calcium and vitamin D.
– Neurological problems: Brain fog, migraines, or tingling limbs.
– Skin rash: Dermatitis herpetiformis.
– Reproductive issues: Infertility or irregular periods.
– Mental health: Anxiety, depression, and mood swings.
Consequences of Nutrient Deficiency
Impaired absorption leads to broader issues:
– Low B12 and folate: Fatigue, memory issues.
– Zinc deficiency: Weakened immunity.
– Vitamin K deficiency: Easy bruising and bleeding.
These nutrient gaps impact physical and mental health.
Diagnosis and Lifelong Management
Diagnosis involves blood tests for specific antibodies, followed by a biopsy. Crucially, testing must be done before starting a gluten-free diet.
Treatment is a strict gluten-free diet for life — not just avoiding bread, but hidden gluten in sauces, packaged foods, and even medications.
Final Thoughts
Celiac disease is a serious, chronic condition. But once identified and managed with a gluten-free lifestyle, many find significant relief and renewed vitality.
If something feels off with your health, especially if unexplained symptoms linger, it is worth looking at whether you are contending with Celiac Disease or another digestive difficulty. Early diagnosis can make all the difference.
Talk to your healthcare provider if you suspect gluten might be affecting your health.
