I was diagnosed with idiopathic urticaria with angioedema—hives and swelling with no clear cause. Could this be connected to my celiac disease?

Living with celiac is complicated enough. Now I’ve been diagnosed with idiopathic urticaria and angioedema—hives and swelling with no known cause.

The Unexpected Diagnosis

Last week I talked about an allergic reaction I had—swollen hands, eyes, and lips. I finally went to the allergy doctor, and the answer wasn’t what I wanted.

The diagnosis: idiopathic urticaria with angioedema. In plain English, that means I get hives and swelling from an unknown source.

What That Means Day to Day

According to the doctor, at times of stress, illness, or even heat, I might suddenly break out in hives while my hands, lips, or eyes swell. She described my immune system as “twitchy,” like it’s just waiting for an excuse to react.

And here’s the kicker: steroids aren’t recommended for quick relief—only antihistamines. The reaction is supposed to resolve within 72 hours. But honestly? I love a course of steroids. They make me feel great, so taking them off the table feels like a loss.

The Celiac Question

So now, not only do I not know if gluten is making me sick, but I also get the “bonus” of potentially breaking out in hives and swelling like the Stay-Puft Marshmallow Man—for no clear reason. Or maybe for no reason at all, just by living my life.

My gut says this is related to my celiac disease, but I have zero confirmation of that. I’m speculating.

There is some research suggesting a higher risk of chronic urticaria in celiac patients (study link). Another, more recent study found that 1 in 20 people with chronic urticaria may have an IgE-mediated allergy to Tissue Transglutaminase 2—the very antigen involved in celiac disease (study link).

To be clear, those studies are about chronic urticaria and angioedema—not idiopathic cases like mine. Chronic means the hives last for six weeks or longer. I cannot imagine being so swollen or itchy for that long.

Triggers and Reality

As a side note, they say alcohol and stress can trigger these issues. But honestly—how do you live life without alcohol or stress? If you know, please share.

Right now, I feel like a ticking time bomb of hives and swelling. I don’t have answers, so I’m going to wait and see what happens. If it comes back, I’ll deal with it then.
