Quick reminder before we get started on this episode. This podcast is based on my personal experiences and isn't medical advice. Have you ever eaten something, felt fine, and then hours later or even the next day felt terrible and wondered, was that gluten? Delayed gluten reactions are incredibly common, but they're also incredibly confusing. Today we're going to talk about why gluten reactions aren't always immediate, what happens in the body, and how to think about delayed symptoms without spiraling into anxiety. If you've ever second-guessed yourself after a reaction, this episode is for you. Let's dive in. Welcome to the Gluten Free Engineer Podcast. I'm your host, Kiri Saunders. In 2011, I was diagnosed with celiac disease, a moment that changed everything. But I was determined not to let it hold me back. With my two engineering degrees, I set out to reverse engineer the gluten-free lifestyle, breaking down recipes, safety tips, travel hacks, and everything in between to rebuild a life I love. Whether you have celiac disease, gluten intolerance, or simply choose to live gluten-free, this podcast is for you. Join me each week as we simplify the gluten-free lifestyle, make it fun, and prove that you don't have to miss out on anything. Welcome back to the show. Today we're talking about why gluten can be a delayed reaction in our body. And for many people, it is. Many people it takes quite a few hours, usually 12 or more, for gluten to react. Some symptoms and some people can react within a few minutes to like 30 minutes or so, but most reactions are delayed. So why do we have this in our head that I should feel bad right after I eat gluten? Well, many people expect gluten reactions to act like food allergies. They expect instant symptoms, but as we know, gluten reactions are immune-driven and not always immediate. It's something that our body is either intolerant to or we have an immune response to. So gluten reactions are not like you know, traditional allergies like peanut allergies, wheat, milk allergies, they don't always happen within minutes. And for most people, they are delayed, and that delay creates the confusion and can create a lot of anxiety too behind it as well, waiting to see if something's going to happen. So let's talk about why that actually takes time. Why does the immune system take time? So in celiac, if you have that, gluten triggers an immune response. And it can take your body a little bit to see that because it needs to get through your digestive system to the you know place where you're gonna where it's gonna get triggered, which is in the small intestine. So it's going to take a bit of time for it to have a reaction for uh traditional CLAC type of responses. And if you're intolerant, it's going to, you know, ramp up your immune system and and flare and flare it up. So that's going to take a little bit of time. So that response can take sometimes hours to peak. And symptoms often appear later and not immediately. I do have some symptoms that will happen pretty quickly, but I feel like those symptoms developed over time. The more I healed, the more, the smarter, I guess I would say, the smarter my body got at recognizing this, you know, molecule that is terrible for me and you know causes, you know, my body complete havoc. And so you may, if you've been gluten-free for many years, have immediate symptoms. And that's just because other parts of your body got really smart at sensing what this thing is and knowing what's going to happen later, too. So don't also feel crazy if you, you know, get symptoms within, you know, say 30 minutes or you know, just a few hours. That's also very normal, especially the more you're healed. So we talked about that digestive transit time because we need the gluten needs to get into our small intestine for those that are celiac to really start causing damage. And that can take a different amount of time depending upon your body, you know, how fast you digest food. And so those symptoms can show up when digestion reached certain points in the process. So this can really simplify how this works because it's a little bit, you know, hard to think about whenever we're traditionally used to food allergies, and that can even be like something you contact, you know, a food allergy. If you just even touch your lips or your skin or something, you could potentially have a reaction. With celac disease and gluten, it does need to get into your body at some, you know, somehow, and that is going to cause you issues. Now, you could have skin reactions topically if you're using products on your skin. It's kind of a different system, but you still might be sensitive to that as well. So don't dismiss that totally. And then also, inflammation doesn't always show up right away. Think about it. We're we're putting gluten into our system. Well, hopefully we're not, but we're we're thinking about how this works. We're putting gluten into our system, it needs to go through our digestive system to potentially affect our digestive system if we're sensitive in that way. We also have symptoms like brain fog. Well, how long would that take? So if you think about it, we probably need to digest all the food, the you know, the components need to get into our the rest of our body and into our bloodstream, and that's going to take a bit for the brain fog potentially to happen. Joint pain is also similar. Usually joint pain comes from you know inflammation in I wouldn't say just like an instant inflammation, usually, at least in my experience, it's usually you know repeated exposure or stress that can compounds exposure and makes your joints hurt. So joint pain is going to take a little bit longer. Now, headaches that could vary. That could be really quickly you could get a headache. I can get a headache simply from smelling bread in the bread aisle. Now, that's not a true reaction from exposure per se, but that's my body saying, Oh, I smell this thing that is dangerous to my body, so I'm going to give her a headache so that she leaves this area. That's how that part works. But you could get headaches and migraines from the actual exposure to it as well, which I get migraines more so from soy than from gluten, but I do get migraines from um eating foods that aren't compatible with my body. You could also get very tired. This is your immune system trying to fix yourself, trying to, you know, fight off this foreign thing that's entered into your body. It could be just the inflammation is causing you to be tired too. You could have mood shifts. Gluten has been shown to really affect our brain and our hormones and really all of our systems in our body. So you may have these symptoms as well. Most of these symptoms here appear 12 to 48 hours later. And what is 48 hours? That's two days. So think about that. You you got to be really diligent about how you're eating and paying attention to your body and looking back potentially two, sometimes three days prior to see whether you've accidentally gotten gluten. So don't feel crazy if you're like, I don't know why I randomly don't feel good. Look back farther. You might need to look back a little bit farther into what you've eaten or what you've been exposed to. I have a lot of people tell me that delayed reactions cause them anxiety. And this is completely understandable because it makes it a lot harder to identify the trigger. You know, we have to be really diligent. What did I eat the previous few days? It can lead to overanalyzing everything. I know for sure. When I was, you know, early on in doing this, I overanalyzed everything because I just wanted to feel better. I had wonderful glimpses of feeling great again, and I just didn't want to mess that up. And then that can make social eating stressful, which can also create, you know, your anxiety. We have lots of podcast episodes on how to, you know, eat socially and be safe and have fun. So look those up if you're interested in those. And we want to try to reduce our anxiety because who wants to be anxious? And it's just so much better on our bodies if we're calm and we can feel that being gluten-free is doable and not unpredictable. And we don't want to, you know, have that unpredictability because that can definitely fuel anxiety. Some people get confused why reactions can be different each time. So, this difference can be the amount consumed, your current inflammation level, your current stress level, your you know, how well have you been sleeping right lately? Do you have anything else messing up your immune system? It could be the type of gluten that you've eaten and how processed it is already. You know, how how much has humans processed this gluten already? Have they broken it down more so it's easier for you to just pass it on through? Um, for me, barley is worse. I gave a worse reaction to the gluten found in barley than I do in the gluten found in meat. Or at least that used to be the case. I thankfully haven't really been exposed either recently, but barley will make me also throw up, as well as other, you know, issues that you don't really want to talk about on a podcast. So this is where we come back to knowing your body and really paying attention to your reactions and what you had, you know, and making that food log when you're early on, or maybe you've relapsed and you're like, I don't know why I, you know, I felt I felt great for years, and I don't know why I don't feel great now. You know, what's going on? What is what is causing me to feel bad. So I want you to rethink delayed reactions. I want you to look at patterns, not one-off incidences. Yes, those can be helpful, but let's look at patterns too. I want to help you avoid that food fear. I want you to be confident when you're eating the food you're eating. I want you to feel confident, you know, listen to some of our other episodes on tips on avoiding gluten so that you can feel a lot better. And I want you to focus on what you can control. That really helps calm our systems. That will help you, you know, calm your immune system too. The less we are stressed, the better our immune systems are. And I want you to keep meals simple if you have symptoms flare up. Go all the way back to the basics of pure, pure, you know, naturally gluten-free items if you have a some, you know, have a flare or accidentally get some gluten. Make this a curiosity. That's how I like to look at it whenever I was first, you know, learning how to be gluten-free. I was curious, curious about what did I do wrong, what happened, or did I get cross-contaminated from somebody else or something else? You know, use curiosity more than panic, and that will help you cope with this a lot better. And if navigating gluten-free feels confusing, we have a wonderful community on Facebook. Just head on over to thlutenfreeengineer.com and you'll see a link at the top for our Facebook group. So, one of the most freeing realizations for me was that delayed reactions doesn't mean I failed. They mean my immune system is sensitive, and sensitive systems deserve care and not shame. So just take care of yourself, listen to your body, and happy gluten-free eating.
