When you’re newly diagnosed and have to completely overhaul your diet, it’s like drinking from a fire hose. Every label, every meal, every conversation about food suddenly feels complicated. Over time, you start to figure out what really works for you — and what doesn’t.

I was diagnosed in 2013. I was sick all the time. One day I asked my husband, “When was the last time you had diarrhea?” He said, “I can’t remember.” I replied, “So going to the bathroom six or seven times a day, urgently, and it’s always liquid — that’s not normal?”

That conversation sent me straight to the doctor. My B12 levels were dangerously low. When my doctor said I needed B12 shots, I mentioned that my niece had just been diagnosed with celiac disease — also with low B12. He said, “No way.” I said, “Please run the celiac tests anyway.”

A week later he called: five out of six tests were more than ten times the upper limit of normal. “You have celiac sprue,” he said. “You don’t need an endoscopy, but if you want one, see a gastroenterologist. Start a gluten-free diet.”

That was it. No roadmap. No practical tips.

Fast-forward to 2018. I found social media groups that told me everything I was doing “wrong”: that I wasn’t strict enough, that my whole house needed to be gluten-free, that one mistake would lead to “celiac cancer.” I took a breath, started reading the science, and asked a lot of questions — including during the Nexvax2 clinical trial, when I had rare access to celiac specialists.

Here’s what I learned — and what I wish I’d heard sooner:

• Not all scary claims hold up. A small but reassuring study suggests kissing after a partner eats gluten carries minimal risk for most people with celiac disease, especially after simple steps like a drink of water or mouth rinse. See research summaries from Celiac.org and Beyond Celiac.
• Cross-contact is nuanced. Some risks are clear (e.g., shared fryers are generally a no-go), but “every crumb = disaster” isn’t evidence-based across the board. For context, see peer-reviewed work on shared fryers (Thompson 2021; Damasceno 2024) and a pilot from Gluten Free Watchdog (white paper).
• Restaurants are a mixed bag. One large analysis found about one-third of “gluten-free” items in U.S. restaurants tested positive for gluten. Helpful perspective here: Columbia Mailman and the full paper summary (PDF) here. This doesn’t mean “never eat out;” it means choose carefully and ask good questions.
• Blood tests aren’t the whole story. Serology can normalize even when intestinal healing lags behind. See Silvester et al., 2017 and later reviews noting limits of serology for mucosal healing.

Bottom line: the gluten-free diet is the cornerstone of treatment, but living well with celiac is more than a checklist. It’s a series of informed choices, habits, and conversations that protect your health and your quality of life.

What would you tell the newly diagnosed?

I’d love to hear your hard-won lessons. What surprised you? What do you wish someone had told you in the first month? Your experience can help someone else breathe a little easier today.
