Can Gluten Cause Fibromyalgia? – Should It Be Avoided?

Can gluten cause fibromyalgia? I’ve heard this question asked so many times and always wondered if there was any truth to it. More research is linking a connection between gluten and fibromyalgia and more doctors are responding to their patients’ FMS by prescribing a gluten free diet. Aside from the obvious carb count that many of us want to avoid, is eating a slice of whole wheat bread really that bad for you? The answer is yes, it can be. Okay, wait… hear me out before you think I’m trying to sabotage your chances of ever getting to enjoy a pizza again, or spaghetti and garlic bread with the family.

Gluten sensitivity and celiac disease

I know it’s a lot to take in, however there could be so many benefits worth considering, by going gluten free. Celiac is an autoimmune disease characterized by stomach upset, gas, bloating and cramps when gluten is consumed. Gluten is a protein that is found in many grains, including rye, barley and wheat. Many people who suffer with celiac as well as IBS also have fibromyalgia, and conversely, many people with FMS develop celiac and or IBS.

Approximately 3 million people in America suffer from celiac disease, but many more are likely living with celiac and are not even aware of it because diagnosis can be so difficult. Even if you do not suffer from celiac, you may have a gluten sensitivity. Gluten sensitivity can be minor and for the most part, go unnoticed or automatically attributed to something else. Feelings of bloating and discomfort are often ignored. On the other hand, celiac disease is a severe sensitivity or intolerance to gluten.

How is gluten connected to fibromyalgia?

Gluten has been shown to cause inflammation in the body leading to many symptoms that are very similar to fibromyalgia which is an inflammatory disorder, including anxiety, whole body pain, sleep disturbances, fatigue, diarrhea, bloating, brain fog and cramps. There is much evidence that a non-celiac gluten sensitivity may be the cause of fibromyalgia, however, more research would need to be conducted before it is conclusive.

Still, whether gluten is actually the culprit or not, eliminating it from the diet can certainly help and has already helped many who suffer with FMS. It is no surprise that many people who suffer with fibromyalgia, including some of my own clients, have  noticed a significant reduction in their symptoms. In some cases they have even reported complete symptom relief after adopting a gluten free life style.

In one study conducted in 2014 involving 97 FMS patients with comorbid IBS showed “a slight but significant improvement in all symptoms” after following a gluten-free diet for one year. The study goes on to state: “our findings suggest that further studies of the subject are warranted.” There are more studies pointing to the effectiveness of going gluten-free, and I believe that they are absolutely warranted.

If you decide to try a gluten free diet, make sure to check product labels, here is a quick list of what to avoid:

  • Wheat (all forms)
  • Barley
  • Bulgar
  • Rye
  • Seitan
  • Couscous

Here are some of the many foods you can still enjoy:

  • Chickpea flour
  • Arrowroot
  • Amaranth
  • Buckwheat
  • Cassava
  • Quinoa
  • Rice
  • Tapioca
  • Soy
  • Corn
  • Oats (note that oats are often processed in gluten-containing facilities and therefor cross contamination may have occurred.)

Some people notice even greater health benefits and a reduction in overall pain once they remove dairy from the diet as well. It is possible to have a sensitivity to lactose, the natural sugar contained in milk and other dairy products. Everyone can benefit from staying away from heavily processed food and trans-fats. If you see the words hydrogenated or partially hydrogenated oil on an ingredients list, it contains trans-fat.

Sugar, another inflammatory threat.

Sugar has also been shown to cause inflammation, not to mention its connection with type 2 diabetes, cancer, obesity, tooth decay, heart attack, anxiety and what’s known as ‘sugar crashes.’ Much like gluten, sugar causes inflammation in the body that can worsen joint pain.

Artificial sugar substitutes such as Sucralose and Aspartame can also contribute to inflammation and pain. Try natural sweeteners like Stevia (Truvia). Check product labels for added sugar and be aware that sugar can also be disguised by other names as well, here is a quick list of what to lookout for:

  • Sucralose (sugar)
  • Galactose
  • Glucose
  • Lactose
  • Maltose
  • Corn syrup
  • High fructose corn syrup
  • Dextrin
  • Dextrose
  • Maltodextrin
  • Fructose
  • Molasses
  • Barley malt
  • Fruit juice
  • Cane sugar
  • Evaporated cane juice
  • Beet sugar
  • Brown sugar
  • Golden sugar
  • Maple syrup
  • Honey

Going gluten-free is hard!

I’m not going to lie to you, it’s not going to be easy. But it’s not extremely difficult either. I personally have been gluten free for about 3 years now, and it does get easier. Don’t get me wrong, I still mess up from time to time, but I avoid gluten whenever I can. Thankfully there are a lot more gluten free options these days, including gluten free pasta, pizza dough and bread.

Gluten free options are available

If you are going to opt for a gluten- free snack, however, make sure that it is not overly processed or full of chemicals etc. Try to purchase organic, GMO free products whenever possible or at least goods that contain simple, pronounceable ingredients. Please keep in mind that everyone is different, and some may experience relief almost immediately while for others it may take longer.

If you are unsure if you have a gluten sensitivity or are whether giving up gluten can help, my suggestion would be to commit to a gluten free and dairy free diet for 6 months. If at this point you are still not sure, try adding dairy back into your diet and see how your body reacts. Then slowly add gluten back into your diet to see how your body responds once it’s been away from it for so long. If you notice your symptoms coming back or worsening, there is a good chance you have a sensitivity to dairy, gluten or both.

The benefits

While there may be some sacrifice involved in making certain diet changes, including giving up gluten, many will attest to the fact that the benefits certainly outweigh the difficulty or inconvenience. If you feel that following a specific diet plan may help you, the paleo diet might be worth a try, it is fairly low carb, gluten and dairy free. The ketogenic diet is a great choice for avoiding sugar as it is extremely low carb. Keep in mind, however that most keto diets still allow for both gluten and dairy, should that be something you want to avoid. Of course you should always check with your Doc first, especially if you are a diabetic.

Thanks for taking the time to read this post, I hope it has helped. As always your questions and comments are more than welcome!

    Hi there!  Many of the things you listed were new to me as far as gluten goes.  I did not realize that so many people are gluten intolerant.  The pictures of the breads, made me hungry. Your so knowledgeable about the topic.  How many people have the celiac problem?  Is it developed over time or are people born with this?  Does gluten cause this?  All the Best, Krista

      Thanks so much for the comment. Celiac disease affects about 1% of the population, however another 6% or so have a non Celiac sensitivity to gluten. Celiac can also develop at any age, so it’s always a good idea to pay attention to the warning signs such as bloating, fatigue, weight loss and iron deficiency anemia. The good news is that there are now plenty of great gluten free options available out there to make the transition a lot easier. I’m glad you found this article informative and I hope I’ve helped to answer your questions. Thanks again!

    Awesome and insightful post you’ve got here. I believe so much in going gluten free for fibromyalgia. I went gluten free  four weeks ago., and my pain level went from a 10 to a 2. I was really addicted to nose spray for 5 years. I no longer need it. My niece also went gluten free and no more sinus infections. This article is goint to enlighten many people, so I’m sharing.

      Jordan Smith,
      Congrats on going gluten free four weeks ago! I’m so glad to hear that it’s helped you and your niece. I had similar problems myself, many of which I didn’t even relate to gluten sensitivity, until I gave it up. I’m glad I did. Thank you so much for the feedback and the share, hope you have a great day!

    I am really glad to found this article. I suffer severely with bloating and my diet sounds like it is pure gluten. I appreciate the lists of “do not eat” and also “what to eat”. I am really starting to like chickpeas ;)). The lists of sugars is crazy. That is my down fall. This article is easy to follow and the whole site is full of useful information. Thank you

    Best wishes

      Thank You!
      I’m so glad that you have found the information in this blog useful. I know that it can be surprising for some, when they learn that giving up gluten can help relieve certain symptom they may have had all their lives. Sugar is also a big one because it’s literally in everything these days! Still, giving up sugar was one of the best choices I’ve ever made. Thanks again for your comment.

    Hi! The very first time I was told about the relationship between gluten and fibromyalgia it was difficult for me to believe. But today there is so much information and the facts prove that it is so. 

    Going glutten free is hard. But I have understood this is the only option for me. Thank you very much for this post.

      Thank you for the comment. Yes, there is a strong link between gluten and fibromyalgia. I know going gluten free can sometimes be a struggle, I hope that you are feeling much better though as a result and good luck with it.

    Thank you for this great article. I was wondering if gluten could cause fibromyalgia. Thanks for explaining how gluten can cause inflammation which can lead to fibromyalgia symptoms. Personally I went gluten-free probably four or five years ago. I have not had any gluten since. I did not know that it would still be okay to have oats! Thank you for that information, maybe I will have some oats. I have mainly been having rice for carbohydrates. 

    I also gave up sugar four or five years ago and again I have not had any since then. When I read an article like yours today, it reminds me why that was such a good decision. Once you adjust to not having the gluten or sugar, it eventually becomes easy because your body stops craving it and also your mind stops craving it. Thank you for your expertise on these nutritional subjects and have a great day.

      Thank you for the comment! I’m so glad to hear that going gluten free is working out so well for you. Yes, you can still have oats, and because they contain a large amount of high viscosity fibre, they will keep you full for a long time and they don’t raise blood sugar as quickly as some other carbs may. This means no sugar crash later and no cravings, like you mentioned! I like Red Mills steal cut oats with a small sprinkle of stevia, cinnamon and a splash of unsweetened vanilla almond milk. Just be sure that whatever brand you buy, they were manufactured in a gluten free facility, other cross contamination is a possibility. Enjoy!
