What the Latest Research Says About Celiac (in Plain English)
Sometimes I fall down a research rabbit hole… and today was one of those days. 📝 In digging through studies for another article, I found a few pieces of information that I think are really important for all of us to know and understand.
I know this isn’t the fun, lighthearted stuff I usually share—no snacks, travel tips, or party invites here—but understanding the science behind celiac disease matters. The more informed we are, the better we can advocate for ourselves and others. So here’s a quick roundup of what stood out (with links):
1) A Single Elevated TTG IgA Isn’t Enough for a Diagnosis
Celiac disease cannot be diagnosed by an elevated tissue transglutaminase (TTG) IgA alone—even if it’s more than 10× the upper limit of normal. A single abnormal test isn’t enough. Diagnosis requires confirmation with either a positive endomysial antibody (EMA) IgA or an endoscopy.

2) In T1D Kids, Post-Meal CGM Patterns (Not Lows) Were Linked to Undiagnosed Celiac
For my type 1 diabetes friends, this was fascinating. It’s often assumed that celiac in T1D shows up as more lows (hypoglycemia). This analysis found the opposite: unusual after-meal blood sugar patterns—not low blood sugar—were associated with undiagnosed celiac in kids using CGM.

3) Teens with Celiac May Have Higher Risk of Body Dissatisfaction
This one hits close to home. The study found that adolescents with celiac disease had higher rates of body dissatisfaction and should be periodically evaluated for mood-related concerns. My take? Honestly, all teens deserve regular mental-health check-ins—but celiac can add another layer during an already tough season of life.

Big picture: Celiac disease is more than just what we eat—it intersects with how our bodies respond, how we’re diagnosed, and how we feel mentally and emotionally. Staying informed doesn’t have to be overwhelming; sometimes it’s just taking a moment to read, reflect, and tuck these insights away. The science may not always be light reading, but it empowers us to make better choices, ask smarter questions, and support each other more fully. 💚
