If you’ve been diagnosed with Hashimoto’s thyroiditis, you’re probably sifting through a lot of advice. Some of this advice you asked for. Some of it you’ve been told by friends and family. This is especially true for what you should or shouldn’t eat.
At this point, you’ve probably wondered about gluten. You’re not alone. One of the most common questions we get at SIE Medical is: “Can I still have gluten if I have Hashimoto’s?” The short answer? It depends—but for many people, cutting back or eliminating gluten can make a real difference in how they feel.
Let’s break down the science and help you make an informed decision.
Hashimoto’s Is an Autoimmune Disease—Inflammation Matters
Hashimoto’s isn’t just a thyroid problem—it’s an autoimmune condition. That means your immune system mistakenly attacks your own thyroid tissue, gradually impairing its ability to produce hormones that regulate energy, metabolism, digestion, and more. A core principle of managing any autoimmune disease is reducing chronic inflammation wherever possible—because inflammation is one of the issues that drives symptoms and fuels immune system misfires.
Gluten and Inflammation: A Known Issue
Gluten is a protein found in wheat, barley, and rye. For people with Hashimoto’s, gluten can be a hidden source of inflammation. Here’s why: the molecular structure of gluten resembles that of thyroid tissue. In some individuals, this similarity can confuse the immune system, potentially worsening the autoimmune attack—a phenomenon called molecular mimicry.
Beyond that, gluten has been shown to increase gut permeability (commonly referred to as “leaky gut”) in some people. When the gut barrier is compromised, more inflammatory substances can enter the bloodstream, activating the immune system even more. This creates a vicious cycle of inflammation that can lead to worsening fatigue, brain fog, bloating, and more.
Why It’s Important to Reduce Inflammation from an Autoimmune Standpoint
Inflammation is at the heart of every autoimmune condition, including Hashimoto’s. In autoimmune disease, the immune system becomes overactive and confused—it starts attacking the body’s own tissues as if they were foreign invaders. In the case of Hashimoto’s, that target is your thyroid gland. The more inflammation present in the body, the more fuel you give to this dysfunctional immune response.
When inflammation is consistently high, it amplifies the autoimmune attack on the thyroid, accelerating tissue destruction and worsening hormone imbalances. Over time, this can lead to a greater need for medication, more severe symptoms, and the development of additional autoimmune conditions. Reducing inflammation doesn’t “cure” autoimmunity, but it helps calm the immune system down, reduce the frequency and severity of flare-ups, and protect the thyroid from further damage. It’s one of the most foundational strategies for managing Hashimoto’s long-term.
Why It’s Important to Reduce Inflammation from a Fatigue and Symptom Standpoint
Chronic inflammation doesn’t just affect your immune system—it affects how you feel every single day. Inflammation interferes with hormone signaling, damages mitochondria (the energy factories in your cells), and creates oxidative stress. For people with Hashimoto’s, this can result in deep, persistent fatigue that doesn’t improve with sleep, as well as symptoms like brain fog, headaches, muscle pain, and digestive issues.
Inflammation also disrupts communication between your thyroid and the rest of your endocrine system. That means your adrenal glands, reproductive hormones, and blood sugar regulation can all be thrown off, creating a domino effect that leaves you feeling drained and imbalanced. By reducing inflammation, you’re not just helping your immune system—you’re directly improving your body’s ability to produce and use energy, think clearly, recover from stress, and regulate weight. Less inflammation means fewer flares, fewer symptoms, and a better quality of life.
Not Everyone Reacts the Same: Personalizing Your Gluten Intake
Hashimoto’s doesn’t show up the same way in every person. Some people have mild, well-managed symptoms and can tolerate occasional gluten without major flares. Others are more sensitive and find that even trace amounts trigger days of exhaustion or discomfort.
If you’ve already cut out major inflammatory offenders like alcohol, processed sugar, and seed oils, you might be able to tolerate small amounts of gluten. But in our clinical experience at SIE Medical, we’ve found that many Hashimoto’s patients feel significantly better when they remove gluten from their diet altogether—especially at the beginning of treatment.
Gluten Is Hiding in More Than Just Bread
Going gluten-free doesn’t just mean skipping toast. Gluten can show up in sauces, soups, salad dressings, seasonings, meat substitutes, and even supplements. That’s why it’s so important to start reading labels and choosing certified gluten-free products when possible. The goal isn’t to be perfect overnight—it’s to become more aware and make choices that reduce your overall inflammatory burden.
You Don’t Have to Navigate It Alone
Managing Hashimoto’s is complex, and diet is just one piece of the puzzle. At SIE Medical, we take an integrative approach that looks at your full health picture. We help you evaluate whether gluten is playing a role in your symptoms by:
