Asthma is linked to gluten, study finds (and so did I)

asthma-inhaler1People with celiac disease are more likely to develop asthma, according to a new study published in the Journal of Allergy and Clinical Immunology. And, those diagnosed with asthma are more likely to develop celiac disease. How are asthma and gluten linked? The researchers are not quite sure what makes people with celiac disease have a 1.6 fold increased risk of asthma (60% more likely to have asthma) than those without. However, one of the researching doctors in a Reuter’s Health article on the study, speculated that it is related to vitamin D deficiency.

Since people with celiac disease have damaged intestines, they are unable to properly absorb nutrients. According to the Vitamin D Council, Vitamin D helps “the immune and nervous systems defend the body, with defects in this intricate system leading to autoimmune disorders.” Several studies have shown that lower levels of vitamin D related to higher incidence of asthma in children. Just supplementing with vitamin D isn’t enough if the body can’t absorb it, as is the case with celiac disease. Removal of gluten is the only way to heal the intestines, so that they can begin to absorb vitamins again.

But forget those studies… just look at me. I puffed on asthma inhalers every day for about 25 years and took prednisone when the inhalers weren’t enough. Three months after I started a gluten-free diet after I was diagnosed with celiac disease at age 32, I stopped my medication cold turkey. I never used it again. It has been over 8 years.

I hadn’t considered vitamin D deficiency as a cause of my asthma before reading this new study. I recently had my vitamin D tested and it is low even now, so I can’t imagine what the level was before my diagnosis — I was never tested for vitamin deficiencies in the past.

If you have asthma, I urge you to get tested for vitamin deficiencies and for celiac disease. Think of your asthma as a symptom for which there is a cause. To be able to breathe again — now that is a gift.

  1. Wow. Wow. Wow. I was diagnosed with mild asthma after 6 months of school lunch eating… My husband has had asthma his whole life and has mentioned that even cutting out gluten and dairy just part-time (he’s still eating it at lunch at work “with the guys”), he’s feeling better. Thank you for sharing.

  2. Great stuff! Finally the connection is mainstream! Here is my experience with asthma and gluten and grains…

  3. My 4-yo daughter has suffered from asthma for the last year, to the point of twice daily nebulizers with steroids. This caused weight gain which I believe made the asthma worse as well. She was recently diagnosed gluten-intolerant and only six weeks after going gluten-free she is off all her meds and nebulizer.

    How is that not worth it?

  4. Mrs. Q,
    Aha! Thanks for adding your story.

    That is so great! I know parents of children who are on all kinds of meds – the doctors never suggest food intolerance. Unfortunately, some parents don’t listen to my advice either and keep on with the steroids.

  5. This is so true!! I’ve had asthma for 15 years (started when I was 26, now 40), just recently I tested this theory and went on a strict 4 week ZERO gluten diet. I went from using my inhaler 2-3x a day to 0 times a day. Within the first 3 days of the diet I noticed improvement. I’m a firm believer that asthma was caused by gluten. The best part, I could still drink beer, “Red Bridge” Gluten Free beer!

  6. I’m 25 and have had asthma since a baby. I had a nebuliser at home that I took twice daily with steroids and have been into hospital a few times. Things got better as I cleared puberty but have still been on blue and brown inhalers daily since. I decided to try alter my diet, I was a milk guzzling, gluten on gluten eater (favourite being spaghetti bolognese with garlic bread or pizza and fries)
    Since significantly reducing my gluten intake (limited wholegrain bread, no pasta, gluten free beer) I have been over 8 weeks without using an inhaler for the first time in my life. Long may it continue!

  7. I have been gluten-free for one month and my asthma has dramatically improved. My husband is a biochemist and found research on immune disorders and gluten. He encouraged me to try this new diet. I also have early-onset Parkinson’s and my symptoms have improved a lot since the change in my diet.

  8. Marlana,
    Thanks for posting this – so helpful!

  9. I do not have Celiacs, but I do have asthma. Cutting gluten has reduced my asthma symptoms dramatically. I’ve been tracking it a bit and I’ve found with uncanny certainty – when I each or drink gluten-laden stuff, my asthma is debilitating. It was a mystery as to why over the last few years my asthma has gotten so bad… It appears I’ve developed a gluten allergy.

    Sadly, I’m a professional brewer. I can’t drink too much of my handiwork. This is sad, because gluten-free beer is a monstrosity.

  10. I had second hand smoke induced asthma. Three weeks after going wheat/gluten free to lose weight, the asthma is almost gone. My mild, but fairly chronic stomach pain is gone. I wish I had known sooner, but I am thankful I stumbled on to this. I can now play a little poker in local casinos, without wheezing and coughing for the following week. I have also lost 5 lbs. in three weeks. I hope all Drs. prescribing steroid inhalers to asthmatics become aware of this. Some researchers believe 40 percent of Caucasians may be wheat sensitive.

  11. I have been gluten free for 5 weeks and my asthma is gone…I have not used my daily inhaler nor have I been for my allergy shots. Many other issues have cleared up for me as well, such as my acne and digestive issues. I can breath deep without feeling like its an effot. I am now exercising for a much longer period of time. I have my life back :)

  12. Diagnosed with Celiac at 52. I have had chronic asthma and horrible allergies all of my life. I now realize I have had celiac all my life. My allergist of 30 years never caught it. So much for immunologists. My lings have been chewed up and I now have COPD; never smoked. I have been a health nut all my life. I am the last person people would think of to have COPD. I think celiac destroyed my lungs. I am now 56 and on oxygen 24×7 and will probably need a lung transplant before too long.
