Celiac Disease
Overview
Celiac disease is a chronic autoimmune condition triggered by gluten, a group of proteins found in wheat, barley, rye, and related grains. In people with celiac disease, eating gluten causes an immune reaction that damages the lining of the small intestine and can interfere with nutrient absorption.¹˒² Symptoms vary widely and may involve the digestive system or other areas of health.
At Tangible Health, we take an individualized approach to celiac disease care focused on maintaining a nutritionally complete gluten-free diet, preventing accidental gluten exposure, identifying and correcting nutrient deficiencies, and supporting digestive and overall health. Naturopathic care complements, not replaces, the lifelong gluten-free diet and appropriate medical follow-up.
What Is Celiac Disease?
Celiac disease occurs when a genetically susceptible person consumes gluten, and their immune system responds in a way that damages the villi, the small finger-like structures lining the small intestine that help absorb nutrients.¹˒³ Over time, untreated celiac disease can interfere with the absorption of nutrients such as iron, folate, calcium, vitamin D, and other vitamins and minerals. It may also affect bone health and other systems outside the digestive tract.³˒⁴
Celiac disease is different from a wheat allergy or non-celiac gluten sensitivity. Celiac disease is an autoimmune disease that can damage the small intestine, even in people who experience few obvious digestive symptoms. Once celiac disease is confirmed, treatment requires a strict gluten-free diet for life.⁵
Common Symptoms of Celiac Disease
Celiac disease can look very different from person to person. Some people experience significant digestive symptoms, while others have primarily non-digestive symptoms or very few noticeable symptoms.¹˒²
Digestive symptoms may include:
Diarrhea
Constipation
Bloating or gas
Abdominal pain or discomfort
Nausea or vomiting
Unexplained weight loss
Other signs and symptoms may include:
Fatigue or low energy
Iron-deficiency anemia
Other vitamin or mineral deficiencies
Bone loss or osteoporosis
Headaches
Joint or bone discomfort
Numbness or tingling
Fertility or reproductive concerns
An itchy, blistering skin rash called dermatitis herpetiformis¹˒⁴
Children may also experience poor growth, delayed puberty, or other signs related to inadequate nutrient absorption. Importantly, the severity of symptoms does not necessarily reflect the degree of intestinal damage.
Causes & Contributing Factors
Celiac disease develops through a combination of genetic susceptibility, gluten exposure, and an abnormal immune response.¹˒²
Genetic Susceptibility
Celiac disease is strongly associated with specific genetic variants, particularly HLA-DQ2 and HLA-DQ8. Having these genes does not mean someone will necessarily develop celiac disease, but the condition generally does not occur without the appropriate genetic susceptibility.²
Gluten Exposure
For people with celiac disease, gluten from wheat, barley, rye, and related grains triggers the immune response that damages the intestinal lining.¹˒⁵
Family History
Celiac disease occurs more frequently in close relatives of people with the condition. A family history of celiac disease may therefore be a reason to discuss screening even when symptoms are mild or absent.²
Associated Autoimmune Conditions
Celiac disease occurs more frequently in people with certain other autoimmune conditions, including autoimmune thyroid disease and type 1 diabetes. Your medical history can therefore influence whether testing should be considered.³
Diet, stress, or microbiome changes do not independently cause celiac disease in the way gluten exposure does in a genetically susceptible person.
Our Approach to Celiac Disease
At Tangible Health, we focus on helping you manage celiac disease confidently while maintaining good nutrition and identifying other factors that may be contributing to ongoing symptoms.
Your Gluten-Free Diet & Nutrition
We review your current diet, food-label reading, possible sources of gluten exposure, cross-contact risk, dietary variety, fibre intake, and overall nutritional adequacy. A gluten-free diet should be strict enough to protect the intestine without becoming unnecessarily restrictive beyond what celiac disease actually requires.
Your Nutrient & Digestive Health
Because untreated celiac disease can impair absorption, we may review iron, folate, vitamin B12, vitamin D, calcium, and other nutrients when clinically appropriate.³˒⁴ If digestive symptoms persist despite a well-managed gluten-free diet, we consider whether accidental gluten exposure or another condition, such as lactose intolerance, IBS, microscopic colitis, or another digestive concern, may need assessment rather than automatically assuming the intestine simply needs more “healing support.”³
Your Goals
Your priorities may include learning how to eat gluten-free safely, improving digestive symptoms, correcting nutrient deficiencies, expanding dietary variety, navigating restaurants or travel, supporting bone health, or understanding persistent symptoms after diagnosis. Your care plan is developed around the outcomes that matter most to you.
Treatments That May Be Included
Your individualized celiac-disease care plan may include:
Clinical Nutrition to build a balanced, nutritionally adequate gluten-free diet and navigate food labels, dining out, and cross-contact
Nutraceuticals & Supplements when bloodwork, dietary intake, or clinical assessment identifies a specific nutritional need
Lifestyle Medicine to support bone health, physical activity, sleep, stress management, and overall long-term health
Naturopathic Counselling to support behavioural change, food-related anxiety, adapting to a lifelong gluten-free diet, and sustainable health habits
Medication & Supplement Review to identify potential gluten exposure and ensure supplements are appropriate for your health needs
Collaborative Care with your family doctor, gastroenterologist, registered dietitian, or other healthcare providers when appropriate
The strict gluten-free diet remains the essential treatment for celiac disease. Supplements, probiotics, botanicals, or “gut-healing” protocols cannot make gluten safe to consume or replace gluten avoidance.⁵
What to Expect
Initial Assessment
We begin with a comprehensive review of your digestive and non-digestive symptoms, medical and family history, current diet, gluten exposure, medications and supplements, previous testing, nutrient status, bone-health considerations, and overall health goals.
Celiac Testing & Medical Review
If celiac disease has not yet been diagnosed, testing should ideally occur before starting a gluten-free diet. Eating less gluten can cause antibody levels and intestinal damage to improve, potentially producing a false-negative or inconclusive result.⁶˒⁷ Initial screening commonly includes tissue transglutaminase IgA (tTG-IgA) together with total IgA. Positive or strongly suspicious results may require gastroenterology assessment and, particularly in adults, upper endoscopy with small-intestinal biopsies to confirm the diagnosis.³˒⁶
Personalized Plan
You’ll receive a personalized care plan designed around your diagnosis, current gluten-free diet, nutritional status, digestive symptoms, laboratory findings, health history, and goals. Recommendations focus on maintaining strict gluten avoidance while keeping your diet as varied and nutritionally complete as possible.
Ongoing Support
Celiac disease requires long-term management. Follow-up can include reviewing symptoms, adherence and accidental gluten exposure, celiac antibody levels, nutritional deficiencies, and bone-health considerations. Persistent symptoms despite a gluten-free diet may require additional evaluation rather than simply adding more dietary restrictions.³˒⁸
When to Seek Support for Celiac Disease
Consider speaking with a healthcare provider about celiac testing if you experience:
Persistent diarrhea, constipation, bloating, or abdominal discomfort
Unexplained iron-deficiency anemia
Unexplained nutrient deficiencies
Unintentional weight loss
Persistent fatigue without a clear explanation
Low bone density or osteoporosis at an unexpectedly young age
Dermatitis herpetiformis
A close family member with celiac disease
Another autoimmune condition associated with increased celiac risk¹˒²˒⁴
If you think you may have celiac disease, do not start a strict gluten-free diet before discussing testing with a healthcare provider. Testing is most accurate while you are still regularly eating gluten.⁶˒⁷ People already diagnosed with celiac disease should also seek reassessment if symptoms or nutritional deficiencies persist despite following a gluten-free diet.
Frequently Asked Questions
-
No. Celiac disease is an autoimmune condition that can damage the small intestine. Non-celiac gluten sensitivity may cause symptoms associated with gluten-containing foods but does not cause the characteristic autoimmune intestinal injury seen in celiac disease.³
-
No. Celiac blood tests and intestinal biopsies are most accurate while you are still eating gluten. Starting a gluten-free diet beforehand can lead to false-negative or inconclusive results.⁶˒⁷
-
Testing usually begins with bloodwork, particularly tTG-IgA and total IgA. Depending on the results, age, and clinical situation, a gastroenterologist may recommend an upper endoscopy with small-intestinal biopsies to confirm the diagnosis.³˒⁶
-
No. Celiac disease is a lifelong condition. Following a strict gluten-free diet allows the intestinal lining to heal and helps prevent ongoing damage, but gluten will continue to trigger the disease.⁵
-
Most people with celiac disease can eat specially produced, uncontaminated oats labelled gluten-free. Regular oats are frequently contaminated with wheat, barley, or rye during growing and processing and should not be assumed to be safe.⁹
-
Very careful. Small amounts of gluten transferred through shared food, utensils, preparation surfaces, fryers, or manufacturing can make food unsuitable for someone with celiac disease. Learning how to recognize and prevent cross-contact is an important part of treatment.⁵˒¹⁰
-
Possible reasons include accidental gluten exposure, incomplete intestinal recovery, lactose intolerance, IBS, or another digestive condition. Persistent symptoms should be evaluated rather than automatically leading to an increasingly restrictive diet.³˒⁸
-
Naturopathic care can support a nutritionally complete gluten-free diet, nutrient assessment, digestive symptoms, bone and overall health, and identification of accidental gluten exposure. It complements the gluten-free diet but cannot replace it.
