Endurance Sports And Celiac

3 posts in this topic

I'm wondering if there have been any studies or information on athletes with Celiac and the effects on endurance sports.

I'm working my way back into running with several 42 km full marathons and a 105 km race behind me. This year I'm entered in 2 marathons and one 50 km trail race.

I'm interested to see if there is information specific to this. Thanks.

Hi Scott,

I don't know much about the official journal studies on the subject, but I can tell you that I have 2 full marathons, several half marathons, five half ironmans, and two full ironmans under my belt. All of these were done *after* I was diagnosed as a celiac. Looks like we were diagnosed around the same time!

This year I have two more half ironmans (did one already), a century ride, and a half marathon on the books. Next year is another ironman, and at least one half ironman and hopefully a double century. The short message is: you can do them for sure. I have no doubt you can still ultra marathon. Many of the mainstream electrolyte replacement drinks are gluten free as are the gus, blocks, etc. We can still get enough starches needed to fuel the training on a gluten free diet. I don't see that there would be any effects of being a celiac in all this as long as you are good with the diet and allowing your gut to heal. I was undoubtedly doing my first marathons before I was completely healed and I was feeling great and happy with my times and improvements. I just have to listen to my body like any other athlete so that I don't injure myself.

Hope this little bit of anecdotal evidence helps a bit. ;)

I found a study that showed that strenuous exertion increases intestinal permeability. I had it saved, but that computer crashed. I found it inline with my observations on training for a mini triathlon. I had to clean up my diet from more cc.

    • We can't see the video carle.  The site is banned from celiac com for spamming. Not having seen it, I'd guess they are selling something?
    • Sorry Doit, Ok, I think I see what you are talking about.  The serum IgA test?  The serum IgA is to verify if your body does make IgA antibodies.  Not all of us make that particular antibody type.  you do make IgA antibodies though, and your reading is fairly high.  the way I understand it, the serum IgA is not specific to celiac disease.  It does indicate a level of antibody activity though.  So perhaps you are fighting an infection or something?  Or it is celiac and for some reason your blood levels of antibodies are not high enough to detect right now. The below info on serum IgA is from Quest Labs. ******************************************************************** Test Highlight IgA, Serum    Clinical Use Diagnose IgA deficiencies Determine etiology of recurrent infections Diagnose infection Diagnose inflammation Diagnose IgA monoclonal gammopathy Clinical Background IgA is the first line of defense for the majority of infections at mucosal surfaces and consists of 2 subclasses. IgA1 is the dominant subclass, accounting for 80% to 90% of total serum IgA and greater than half of the IgA in secretions such as milk, saliva, and tears. IgA2, on the other hand, is more concentrated in secretions than in blood. IgA2 is more resistant to proteolytic cleavage and may be more functionally active than IgA1. IgA deficiency is the most prevalent isotype deficiency, occurring in 1/400 to 1/700 individuals. Many patients with IgA deficiency are asymptomatic, while others may develop allergic disease, repeated sinopulmonary or gastroenterologic infections, and/or autoimmune disease. Individuals with complete absence of IgA (<5 mg/dL) may develop autoantibodies to IgA after blood or intravenous immunoglobulin infusions and may experience anaphylaxis on repeat exposure. Elevated serum IgA levels are associated with infection, inflammation, or IgA monoclonal gammopathy. Method In this nephelometric method, anti-human IgA binds to IgA in the patient sample, forming an insoluble complex. The amount of light scattered by this insoluble complex is proportional to the concentration of IgA present in the sample.   ********************************************************************
    • Thanks for yoUr response GFinDC. For what it's worth,  I've eaten gluten daily for at a minimum of 10 weeks now. I have to taste at work, and initiallyni noticed no ill effect until after I'd been consuming it regularly over a period of time. Shortly before I initially went gluten free, I was suffering from unexplainable stomach cramping and issues that did go away when I quit gluten. It didn't come back until just the past couple of weeks though and now I'm remembering how painful, uncomfortable, and smelly the whole situation was 😂    Can you explain what the reflex test (the one I tested above range in) is? 
    • Hi, just looking for some advice as I'm still learning. I'm looking to go to Kenya next week and I'm quite stressed about the journey, I'm not too bothered about while I'm there as I should mostly be able to eat fresh fruit, vegetables and meat. What's the deal with chips (fries) in fast food places and restaurants, should they always be avoided? And how about rice? I've seen packets before that say may contain gluten. Thanks
    • Update! Had my appointment today and the doctor said she was going to order a full celiac panel without me even having to request it! I was overall impressed with how well my doctor handled this and listened to my concerns rather than writing them off like some people's doctors have.
