Living with unexplained digestive discomfort can be challenging, often leading to questions about what you eat. Two common culprits that come to mind are coeliac disease and gluten intolerance. Understanding the distinct coeliac disease symptoms and how they differ from general gluten intolerance is the first step towards managing your health. At Manipal Hospitals, our expert gastroenterologists in Patiala are dedicated to providing precise diagnosis and personalised care for a range of digestive problems, including those stemming from gluten. Approximately 1 in 100 people worldwide are affected by coeliac disease, yet a significant number remain undiagnosed, highlighting the importance of awareness and timely medical intervention.
Synopsis
What is Coeliac Disease?
Coeliac disease is a serious, chronic autoimmune disorder where consuming gluten, a protein found in wheat, barley, and rye, leads to damage in the small intestine. This damage impairs the body's ability to absorb nutrients, leading to a host of health problems. It's not an allergy, but an autoimmune reaction where the body mistakenly attacks its own tissues.
The Autoimmune Response
When someone with coeliac disease eats gluten, their immune system reacts by attacking the villi – tiny, finger-like projections lining the small intestine responsible for nutrient absorption. Over time, these villi become flattened, a condition known as villous atrophy. This critical damage means even if you're eating a healthy diet, your body isn't getting the nutrients it needs, leading to potential deficiencies and long-term health complications.
Coeliac Disease Symptoms
The symptoms of coeliac disease are incredibly diverse and can affect both the digestive system and other parts of the body. Up to 70% of individuals with coeliac disease may experience non-digestive symptoms predominantly, making diagnosis challenging. It’s crucial to recognise these varied presentations:
Digestive Problems:
-
Chronic diarrhoea or constipation
-
Abdominal pain and bloating
-
Excessive gas
-
Nausea and vomiting
-
Weight loss or, less commonly, weight gain
Non-Digestive Symptoms:
-
Fatigue and persistent tiredness
-
Anaemia (often iron-deficiency anaemia)
-
Skin rash (Dermatitis herpetiformis)
-
Bone or joint pain
-
Tingling numbness in the hands and feet (neuropathy)
-
Mouth ulcers
-
Headaches
-
Depression and anxiety
-
Delayed puberty or infertility
-
Dental enamel defects
If you experience a combination of these issues, particularly chronic digestive problems from gluten, consulting a specialist is vital. Early diagnosis significantly reduces the risk of long-term complications, with over 90% of patients experiencing substantial symptom relief and intestinal healing once on a strict gluten free diet.
Differentiating Gluten Intolerance (Non-Coeliac Gluten Sensitivity)
What is Gluten Intolerance?
Non-Coeliac Gluten Sensitivity (NCGS), often referred to as gluten intolerance, describes a condition where individuals experience symptoms similar to coeliac disease after consuming gluten, but without the autoimmune response or small intestine damage characteristic of coeliac disease or a wheat allergy. It's not yet fully understood, but it's believed to involve a different mechanism of immune response or sensitivity.
Symptoms of Gluten Intolerance
Symptoms of gluten intolerance often overlap with those of coeliac disease, making self-diagnosis unreliable. Common symptoms include:
-
Abdominal pain and bloating
-
Diarrhoea or constipation
-
Headaches
-
Fatigue
-
Brain fog
-
Joint pain
Unlike coeliac disease, gluten intolerance does not lead to intestinal damage or long-term complications. However, symptoms can be debilitating and significantly impact quality of life.
Gluten Allergy (Wheat Allergy) vs. Intolerance vs. Coeliac Disease
Key Differences
While often confused, these three conditions are distinct:
-
Coeliac Disease: An autoimmune disorder causing small intestinal damage from gluten exposure. Requires a lifelong strict gluten-free diet.
-
Gluten Intolerance (NCGS): Non-autoimmune, non-allergic reaction to gluten, causing symptoms without intestinal damage. Management involves reducing or eliminating gluten based on symptom severity.
-
Wheat Allergy: An immune system reaction to proteins found in wheat (not just gluten), triggering classic allergic symptoms like hives, swelling, difficulty breathing, and in severe cases, anaphylaxis. It is diagnosed via allergy tests and managed by avoiding wheat.
Diagnosis: The Path to Clarity
Diagnosing Coeliac Disease
Accurate diagnosis is crucial. For coeliac disease, diagnosis typically involves:
-
Blood Tests: Screening for specific antibodies (tTG-IgA, EMA-IgA). It's vital to consume gluten during these tests for accurate results.
-
Small Intestine Biopsy: If blood tests are positive, an endoscopy with a biopsy of the small intestine is performed to confirm villous atrophy. Our experienced gastroenterologists in Patiala utilise advanced endoscopic techniques to ensure precise diagnosis.
-
Genetic Testing: While not diagnostic on its own, testing for HLA-DQ2 and HLA-DQ8 genes can rule out coeliac disease (if negative) or indicate a predisposition (if positive).
Remember, never start a gluten-free diet before getting tested for coeliac disease, as this can lead to false-negative results.
Diagnosing Gluten Intolerance
Diagnosing gluten intolerance is primarily a diagnosis of exclusion. This means ruling out coeliac disease and wheat allergy first. If these are negative, your doctor may recommend an elimination diet where gluten is removed for a period (e.g., 2-4 weeks) and then reintroduced to observe if symptoms return.
Managing Your Condition: The Gluten-Free Lifestyle
Embracing a Gluten-Free Diet
For individuals diagnosed with coeliac disease, a lifelong, strict gluten-free diet is the only treatment. This means avoiding all foods containing wheat, barley, and rye. For those with gluten intolerance, the degree of gluten restriction may vary depending on individual sensitivity. Many patients with coeliac disease report a dramatic improvement in symptoms within weeks of adopting a gluten-free diet, with up to 80% seeing complete resolution of digestive symptoms and improved nutrient absorption within one year.
Navigating a gluten-free diet can be challenging initially, but with proper guidance, it becomes manageable. Our team at Manipal Hospitals is here to support you every step of the way, offering dietary advice and ongoing care.

FAQ's
Gluten is a family of proteins found in grains like wheat, barley, and rye. It acts as a "glue" that holds food together, giving it shape.
Yes, coeliac disease can develop at any age, from infancy to adulthood, even if you've eaten gluten your whole life without issues.
Currently, there is no cure for coeliac disease. The only effective treatment is a strict, lifelong gluten-free diet.
Naturally, oats are gluten-free, but they are often cross-contaminated with wheat during processing. Look for oats specifically labelled "certified gluten-free."
Healing time varies. Children often heal within 3-6 months, while adults may take 2-5 years or even longer for complete intestinal recovery.
