What to Do After a Celiac Diagnosis


A celiac diagnosis usually comes with a printout, a quick "avoid gluten" from the doctor, and not much else. You're left to figure out label reading, cross-contact, restaurant ordering, and what's actually happening inside your gut, all at once, usually while still feeling sick.


I built my own framework for exactly this stretch, because trial and error is the slowest and most demoralizing way to learn it. Here's what the first 90 days should actually look like.



Days 1 to 10: Stop the Damage, Don't Fix Everything


The only job in the first ten days is getting gluten out of your kitchen and your daily food. That's it. Don't try to master restaurant ordering, travel, or every hidden-gluten ingredient in week one. You'll burn out trying to learn everything at once, and burnout is what makes people quit the diet entirely by month two.


Focus on:

  • Clearing out obvious sources: bread, pasta, cereal, flour

  • Replacing your household condiments if you share them with someone eating regular bread (a shared butter tub or peanut jar is a classic cross-contact source)

  • Learning the handful of ingredient names that hide gluten: malt, brewer's yeast, some modified food starch



Days 10 to 30: Learn the Rules, Don’t Just Memorize Products


Once the obvious sources are gone, this is when people usually start memorizing "safe" and "unsafe" food lists. But, you can’t memorize every foods. Instead, learn the actual rules to what gluten means and label reading. For example, understanding the categories: grains that contain gluten, common hidden sources like soy sauce and some seasoning blends, and the difference between naturally gluten-free and certified gluten-free.


This is also when I want you to start reading labels for real, not skimming them. The FDA gluten-free labeling rule sets what "gluten-free" is legally allowed to mean on a package. Knowing that threshold makes label reading faster because you're checking against a standard instead of guessing.



Days 30 to 60: Practice Dining Out Away From Home


By now your kitchen is solid and likely where you are most comfortable. The harder problems are the ones outside it: eating at other people's houses, school or work lunches, restaurants, travel. This is where most of my clients start slipping on staying gluten-free OR opt out of leaving the home all together. This is not because they don't understand the diet, but because they haven't built scripts for saying no, asking questions, or handling a well-meaning host who insists "it's just a little."


Two things help more than anything else here:

  1. A short, repeatable script for restaurants and gatherings, so you're not improvising an explanation every time.

  2. Permission to be direct. "I can't eat that, I have celiac disease" is a complete sentence. You don't owe anyone an apology for it.



Days 60 to 90: Check Your Labs


Somewhere around the two-month mark, most people expect to feel fully better. Some do. Many don't, and that's normal, not a sign you're doing something wrong. Intestinal healing takes months, sometimes longer, and symptom improvement doesn't always track the same timeline as the healing itself.


This is the point where I bring in labs if we haven't already: iron, B12, vitamin D, and a look at whether inflammation markers are trending down. It's also when I start asking about energy, digestion, and mood specifically, because those often lag behind the obvious gut symptoms.



When to Bring in a Dietitian Instead of Guessing


If you're past day 30 and still troubleshooting alone, that's usually the sign to stop guessing. A dietitian who specializes in celiac disease can catch things a general practitioner visit won't: hidden cross-contact sources in your specific routine, whether your symptoms point to something beyond the diet itself, and which labs are actually worth running at your stage.


That's the whole idea behind not doing this through trial and error. You shouldn't have to spend eight months discovering what a specialist could tell you in one conversation.



Where This Leads: Raising Celiac Kids


If you're navigating this for your child rather than yourself, the same three-phase structure applies, with a few kid-specific wrinkles: school, other parents, and a child's own understanding of what's happening to their body. That's exactly what our Raising Celiac Kids curriculum walks through, step by step, so you're not building the plan from scratch while also managing a newly diagnosed kid.


For a limited time, the curriculum is 50% off. If you're in the middle of your own first 90 days or your child's, get the Raising Celiac Kids curriculum before the offer ends.
