Understanding Celiac Disease: Beyond the Gluten-Free Trend to Medical Necessity

Celiac disease is often discussed in the same breath as wellness trends and gluten-free menus. But for many in Toronto, going gluten-free isn’t a lifestyle choice—it’s essential medical treatment. At Care&, we see the consequences of delayed or incomplete diagnosis: years of fatigue, iron deficiency, anxiety, infertility concerns, and confusing digestive symptoms. The good news is that with the right testing, a clear diagnosis, and practical support, people with celiac disease can feel well again.

This article explains what celiac disease is (and isn’t), how it’s diagnosed in Canada, what living gluten-free truly requires, and when to seek care. You’ll also find practical steps you can take today, whether you’re newly diagnosed or wondering if gluten may be a problem for you or your child.

Why This Matters Now

  • •
    Celiac disease affects about 1% of Canadians, yet many remain undiagnosed for years.
  • •
    Symptoms can be subtle or non-digestive (like low iron or brain fog), leading people to try gluten-free diets before testing—making diagnosis harder later.
  • •
    A correct diagnosis guides long-term monitoring of nutrition, bone health, and associated autoimmune conditions—and protects you from unnecessary restrictions if gluten isn’t the issue.

If you’ve searched “medical clinic near me” hoping for answers, we understand how frustrating it can be. At Care&, Nurse Practitioners lead primary care with unrushed, on-time medical appointments, on-site lab sample collection, and unlimited healthcare appointments through a membership model—designed so you can get clarity, not quick fixes.

Celiac Disease in Plain Language

Celiac disease is an autoimmune condition. When someone with celiac eats gluten—a protein in wheat, barley, and rye—the immune system attacks the small intestine. Over time, this damages the intestinal lining and interferes with nutrient absorption.

Celiac disease is not:

  • •
    A food intolerance
  • •
    A wheat allergy
  • •
    The same as non-celiac gluten sensitivity (NCGS)

While NCGS can cause symptoms with gluten, it doesn’t damage the intestine in the same way and requires a different approach. That distinction is one reason proper testing matters.

How Common Is It—and Who’s at Risk?

  • •
    Prevalence is roughly 1% in Canada.
  • •
    Risk increases if you have a first-degree relative with celiac, type 1 diabetes, autoimmune thyroid disease, Down or Turner syndrome, autoimmune liver disease, or dermatitis herpetiformis (an itchy, blistering rash).
  • •
    Celiac can develop at any age—children, teens, adults, and older adults.

Symptoms: It’s Not Just About the Gut

Celiac disease can be “classic” (digestive symptoms) or “non-classic” (extra-intestinal). Some people have no obvious symptoms at all.

Common digestive symptoms:

  • •
    Bloating, abdominal pain, diarrhea, constipation
  • •
    Unexplained weight loss (or in children, poor growth)
  • •
    Nausea, vomiting

Common non-digestive symptoms:

  • •
    Iron deficiency anemia not explained by other causes
  • •
    Fatigue, brain fog, headaches
  • •
    Osteopenia/osteoporosis, bone or joint pain
  • •
    Elevated liver enzymes
  • •
    Mouth ulcers, dental enamel defects
  • •
    Tingling or numbness in hands or feet
  • •
    Mood changes, including anxiety or low mood
  • •
    Fertility challenges or recurrent miscarriage

Pediatric-specific clues:

  • •
    Slow growth or delayed puberty
  • •
    Irritability, poor appetite
  • •
    Abdominal distension
  • •
    Chronic constipation or diarrhea

If you recognize yourself or your child in a few of these, it’s worth a conversation with a primary care provider. Care& offers Nurse Practitioner-led pediatric care and family practice that can evaluate symptoms holistically, not just one at a time.

The Most Important Step Before Testing: Don’t Stop Eating Gluten Yet

This is crucial. Blood tests and intestinal biopsies are most accurate when you are still eating gluten regularly. If you go gluten-free first, tests may show false negatives, and your care team may recommend a supervised “gluten challenge” to confirm diagnosis later.

At Care&, we guide patients through this decision carefully so you aren’t navigating it alone.

How Celiac Disease Is Diagnosed in Canada

Diagnosis combines history, blood tests (serology), and often an upper endoscopy with small intestinal biopsies.

1) Blood Tests (Serology)

  • •
    Tissue Transglutaminase IgA (tTG-IgA) is the first-line test.
  • •
    Total IgA is checked at the same time. If you’re IgA deficient, IgG-based tests (such as deamidated gliadin peptide IgG) can be used.
  • •
    High tTG-IgA levels plus positive endomysial antibody (EMA) increase the likelihood of celiac.
  • •
    These tests are most informative when you’re consuming gluten.

2) Endoscopy and Biopsy

  • •
    A gastroenterologist takes small tissue samples from the small intestine to look for characteristics of celiac (villus atrophy).
  • •
    Biopsy remains the gold standard for most adults in Canada.

3) Genetic Testing (HLA-DQ2/DQ8)

  • •
    Not diagnostic on its own.
  • •
    Helpful when the diagnosis is unclear or if you’ve already cut out gluten. If you do not have DQ2 or DQ8, celiac disease is very unlikely.

At Care&, Nurse Practitioners order initial labs and, if indicated, refer to gastroenterology for endoscopy. Our on-site lab services collect samples and send them to external laboratories for analysis, and results flow right into the Care& app so you can review them and ask questions without waiting for a paper trail.

Care& App Feature

Access your lab results directly through the Care& app as soon as they’re available. Review your results before your follow-up appointment so you can come prepared with questions.

What If You Already Stopped Eating Gluten?

Don’t worry—this is common. We will:

  • •
    Review your history and current symptoms.
  • •
    Consider genetic testing (HLA-DQ2/DQ8).
  • •
    If celiac remains likely and you’re open to confirmation, discuss a medically supervised gluten challenge (how much and how long depends on your situation; often several weeks of daily gluten intake before retesting). This is personalized and may involve gastroenterology input.

Our role is to ensure you understand your options and feel supported whichever path you choose.

After Diagnosis: What “Gluten-Free” Really Means

A strict, lifelong gluten-free diet is the only current treatment for celiac disease. “Strict” means more than avoiding obvious wheat bread or pasta. It includes preventing cross-contact and reading labels closely.

What to avoid:

  • •
    Wheat, barley, rye, and foods made from them (e.g., most conventional breads, pastas, many cereals, certain sauces/soups).
  • •
    Malt and malt extract (barley).
  • •
    Many beers (unless explicitly gluten-free).

Oats:

Many people with celiac can include “pure, uncontaminated oats” introduced after stabilization on a gluten-free diet, typically up to a moderate daily amount. Some individuals don’t tolerate oats. We individualize recommendations and monitor symptoms and labs.

Cross-contact matters:

Shared toasters, cutting boards, pasta water, bulk bins, and fryers used for breaded foods can transfer gluten.

Canadian labeling basics:

  • •
    In Canada, gluten sources must be clearly declared on packaged food labels.
  • •
    A “gluten-free” claim is regulated and must meet strict criteria (typically under 20 ppm gluten).
  • •
    Advisory statements like “may contain wheat” indicate possible cross-contact; decisions depend on your sensitivity and guidance from your care team.

At Care&, nutrition counseling is part of comprehensive management—patients appreciate practical shopping lists, label-reading strategies, and restaurant scripts you can use with confidence.

Healing and Monitoring: What to Expect

Most people begin feeling better within weeks of going gluten-free; complete intestinal healing can take months to years, especially in adults.

Early and ongoing monitoring typically includes:

  • •
    Symptom check-ins and nutrition review
  • •
    Lab tests to assess deficiencies and healing: complete blood count, ferritin and iron, vitamin B12, folate, vitamin D, calcium, liver enzymes, and sometimes thyroid function
  • •
    Celiac-specific antibodies (e.g., tTG-IgA) to monitor response to the diet
  • •
    Bone health assessment: a bone density scan may be recommended, particularly if you’re diagnosed as an adult, have fractures, or have risk factors
  • •
    Vaccination review: certain immunizations may be considered based on your overall risk profile; we individualize recommendations

Care& App Feature

Use the secure messaging feature in our app to connect with your healthcare team between appointments for quick questions or emotional support as you navigate dietary changes.

Eating Out, Travel, and Daily Life in Toronto

Practical strategies that work:

  • •
    Learn a simple script: “I have celiac disease and must avoid all gluten, including cross-contact. Can you prepare my meal with clean cookware and a separate fryer?” If the answer is uncertain, choose a different dish or another restaurant.
  • •
    Seek restaurants with clear gluten-free procedures, not just “gluten-friendly” labels.
  • •
    In grocery stores, spend extra time in the first few weeks reading labels. Build a roster of “safe brands” to shorten trips later.
  • •
    For travel, pack reliable staples (crackers, oats if tolerated, nut butters) and preview menus online.
  • •
    In workplaces and schools, ask about kitchen protocols. Care& supports employers through corporate health services and workplace wellness seminars—useful for aligning cafeteria practices and team events with medical needs.

When to Suspect Celiac—and What to Do Next

Consider an evaluation if you or your child has:

  • •
    Ongoing digestive symptoms without a clear cause
  • •
    Iron deficiency anemia, low B12/folate, or low vitamin D
  • •
    Unexplained fatigue or brain fog
  • •
    A family history of celiac disease
  • •
    Osteopenia/osteoporosis, especially at a younger age
  • •
    Type 1 diabetes or autoimmune thyroid disease plus new symptoms

Action steps you can take now:

  1. Keep eating gluten until you’re assessed, unless your clinician advises otherwise.
  2. Track symptoms, weight changes, and any over-the-counter supplements you take.
  3. Book a medical appointment with a primary care provider who understands celiac workups.
  4. If tests confirm celiac, ask for a referral to a registered dietitian experienced in celiac nutrition.
  5. Plan your first month gluten-free with easy, whole-food staples: rice, quinoa, potatoes, gluten-free oats (if advised), legumes, plain dairy, eggs, fruit, vegetables, and lean proteins.

At Care&, Nurse Practitioners in Toronto provide comprehensive primary care comparable to family doctors—ordering appropriate tests, coordinating referrals, and helping you translate results into daily routines. If you’re trying to decide between a walk in clinic and a full primary care relationship, our appointment-based model is an alternative to walk-in clinic visits that often don’t allow for long-term follow-up.

Special Considerations and Associated Conditions

Dermatitis herpetiformis

An intensely itchy, blistering rash related to celiac. Diagnosis typically involves a specialized skin biopsy; treatment includes a strict gluten-free diet and sometimes medication for symptom relief during the transition.

Thyroid and type 1 diabetes

Autoimmune conditions that often coexist. We check in on thyroid function and coordinate care with endocrinology when appropriate.

Bone health

Untreated celiac can weaken bones. We assess risk and consider bone density testing and targeted supplementation.

Fertility and pregnancy

Gluten-free adherence supports improved outcomes; we provide preconception counseling and prenatal coordination.

Mental health

Fatigue, anxiety, and social stress are common. Care& integrates anxiety treatment into primary care to support the whole person.

A Practical Week-One Grocery Checklist
