Living with celiac disease can be challenging, especially when it feels like the world is full of hidden threats to your health. While we know gluten is the main trigger for those of us with celiac disease, there are other environmental factors that can exacerbate symptoms or prolong recovery.
Other elements in your surroundings can exacerbate or prolong symptoms, sometimes by triggering inflammation, disrupting gut health, or weakening the immune system.
Understanding these triggers can help you avoid flare-ups and take control of your health.
In this blog post, we’ll explore common environmental triggers, how they affect celiac symptoms, and what you can do to minimize your risk of exposure.
What Are Environmental Triggers?
Environmental triggers are factors in your surroundings that can provoke or worsen symptoms. These triggers can range from the obvious, like gluten contamination, to less obvious factors such as pollutants, stress, or certain chemicals in your everyday environment.
While gluten is the most well-known trigger for celiac disease, these environmental factors can also contribute to increased inflammation, poor gut health, and a harder time managing the condition.
Cross Contact with Gluten
For those of us celiac disease, even trace amounts of gluten can trigger a reaction. Cross contact occurs when gluten free food comes into contact with gluten-containing items. This is one of the most common environmental triggers for celiac symptoms.
At home: Shared kitchens are often a minefield for cross contact. Using the same toaster, cutting boards, or utensils as someone who eats gluten can lead to accidental exposure.
Outside the home: Dining out in restaurants, cafes, or even at friends’ houses poses risks. Staff may not always understand cross contact protocols, and gluten can lurk in sauces, dressings, or even fried foods.
What you can do: Create a separate area for gluten free cooking at home, or at least have dedicated utensils and cookware. When dining out, always ensure the restaurant understands your needs, and always ask about how food is prepared.

Non-Gluten Environmental Triggers
Aside from gluten, other environmental factors can worsen symptoms or weaken your immune system.
Pollutants and chemicals: Air pollution, household cleaning products, and pesticides can all irritate the gut or the immune system. Though not as direct as gluten, chronic exposure can lead to an exacerbation of symptoms over time.
Food additives: Certain food additives like preservatives, emulsifiers, or artificial flavors can disrupt gut health or trigger inflammation. Even though these additives are gluten free, they can still cause discomfort.
What you can do: Opt for natural, non-toxic cleaning products in your home and reduce exposure to harmful chemicals. When it comes to food, try to avoid overly processed items and stick to mostly whole, minimally processed foods.
Stress and Lifestyle Factors
Stress is one of the most overlooked environmental triggers. While stress doesn’t directly cause a celiac flare-up, it can weaken your immune system, making your body more susceptible to symptoms and a slower recovery.
Impact on symptoms: Stress can cause the body to produce more cortisol, which may lead to increased gut permeability (leaky gut). For those of us with celiac disease, this can aggravate existing symptoms like bloating, fatigue, and digestive discomfort.
Lifestyle adjustments: Incorporating stress-management techniques such as mindfulness, meditation, or regular exercise can significantly reduce the impact of stress on your health.
What you can do: Prioritize self-care by creating a stress-relief routine. Whether it’s through yoga, spending time in nature, or journaling, find what helps you relax and make it a regular part of your life.
Hidden Sources of Gluten in Non-Food Items
It’s not just food where gluten can hide—it may also be present in cosmetics, skincare products, and medications.
Cosmetics and skincare: Gluten-containing ingredients are sometimes used in makeup, lotions, or hair products including dry shampoo which can be inhaled. While gluten doesn’t penetrate the skin, accidental ingestion (e.g., from lipstick or hand cream) may trigger symptoms in some people.
Medications and supplements: Gluten can be used as a binding agent in some medications or supplements. If you’re not careful, you could unknowingly ingest gluten from these sources.
What you can do: Check the ingredient lists on personal care products and opt for gluten free alternatives. For medications, ask your pharmacist to confirm whether they are gluten free or consult gluten free medication databases online.

Travel and Public Environments
Traveling can expose you to environmental triggers you might not deal with on a daily basis, especially when it comes to eating out or staying in hotels.
Airplane food and hotel stays: Airplane meals are often limited in gluten-free options, and the risk of cross-contamination is high. Hotels may also not be equipped to handle special dietary needs unless you specifically request it.
What you can do: Bring your own snacks when traveling and, if possible, book accommodations with kitchen facilities. Contact restaurants and hotels ahead of time to discuss your dietary requirements to ensure safe eating options.

Sensitivities Beyond Gluten
Many people with celiac disease develop sensitivities to other foods beyond gluten, such as dairy, soy, or corn. This can be a result of gut damage caused by celiac disease, which makes it difficult for the body to digest these foods.
Elimination diets: If you suspect additional food sensitivities, you might want to try an elimination diet to identify the culprits. Cutting out potentially irritating foods for a period and then slowly reintroducing them can help pinpoint the problem.
What you can do: Consider completing an Elimination Diet such as Eliminate (details here) or use a Health Tracker such as this one here to identify any additional sensitivities and adjust your diet accordingly.
While gluten is the most obvious trigger for celiac disease symptoms, many environmental factors can also contribute to flare-ups or prolonged discomfort. By understanding and managing these triggers—by avoiding cross contact, reducing exposure to toxins, and learning to manage stress—you can take control of your health and live more confidently with celiac disease.
Remember, the key to success is knowledge and preparation. By taking small, practical steps to avoid environmental triggers, you can enjoy a healthier, more balanced life while minimizing the risk of unwanted symptoms.
