Book an appointment with a primary care physician or a gastroenterologist—a.k.a. a stomach wizard. They’re the ones who get paid to take your complaints seriously. First, they’ll order a blood test called the tTG-IgA test. This checks for antibodies that shoot up like a flare when gluten is present. Fun fact: if you have IgA deficiency (common in Celiacs), the test might be useless—so they’ll also check your total IgA levels. It’s like a spy thriller, but with more toilet paper.
If the blood test comes back positive—congratulations, you’re officially in the “gluten-is-out-to-get-me” club—your doctor will want a biopsy. Yes, a real biopsy, the kind where they stick a camera down your throat while you’re sedated and take tiny clippings of your intestine. It sounds medieval, but it’s the gold standard. Don’t skip this step; many people have negative blood tests but positive biopsies. You don’t want to be that person who gives up pizza for nothing.
