Think your belly hurts after bread or pasta? You’re not alone. Gluten sensitivity can cause real symptoms, but it isn’t the same as celiac disease or a wheat allergy. This page gives clear, useful steps to spot the problem, get tested, and manage symptoms without guesswork.
Celiac disease is an autoimmune condition. It damages the small intestine and needs a formal diagnosis. Doctors use blood tests (tTG-IgA) and often an intestinal biopsy to confirm it. Don’t start a gluten-free diet before testing—results can be misleading.
Wheat allergy is an allergic reaction. Tests include skin-prick or specific IgE blood tests. Reactions can be immediate and sometimes serious, like hives or breathing trouble.
Non-celiac gluten sensitivity (NCGS) is diagnosed by excluding celiac disease and wheat allergy. There’s no single lab test for NCGS. If tests for celiac and allergy are negative and symptoms improve when you avoid gluten, NCGS is likely. A supervised gluten challenge can help confirm this.
Going gluten-free works for many people, but it takes planning. Start with whole, naturally gluten-free foods: rice, potatoes, corn, quinoa, beans, fruits, and vegetables. Replace wheat-based bread and pasta with certified gluten-free versions if needed.
Read labels every time. Gluten hides in sauces, dressings, processed meats, and some medications. Look for "gluten-free" or check ingredients for wheat, barley, rye, malt, and brewer’s yeast. Oats are often cross-contaminated—buy certified gluten-free oats if you eat them.
Watch cross-contamination at home and when dining out. Use separate toasters and utensils, or ask restaurants to prepare food on a clean surface. Simple tools like silicone mats, dedicated cutting boards, or sealed containers for gluten-free flours cut risk a lot.
Think about nutrition. People who drop gluten can miss fiber, iron, B vitamins, and calcium. Swap in whole grains like quinoa and brown rice, and consider a dietitian consult to avoid gaps—especially for kids, pregnant people, or anyone with medical conditions.
If symptoms are mainly bloating, gas, and irregular bowel habits, also check for IBS and FODMAP sensitivity. Some people improve on a low-FODMAP plan rather than strict gluten removal. A clinician or dietitian can help sort this out.
See a doctor if you have persistent weight loss, severe belly pain, blood in stools, or signs of anemia (fatigue, pale skin). If you suspect a wheat allergy and have breathing trouble, seek emergency care immediately.
Short, practical step: don’t self-diagnose. Get tested for celiac first, then try a supervised elimination if tests are negative. Small changes—reading labels, switching a few staples, and checking nutrient intake—often make a big difference.

In my recent blog post, I explored the connection between acute diarrhea and gluten sensitivity. It turns out that for some people, consuming gluten can trigger an immune response, leading to inflammation and damage to the intestinal lining. This damage can cause a variety of symptoms, including acute diarrhea. By following a gluten-free diet, those with gluten sensitivity can often alleviate these symptoms and improve their overall digestive health. If you suspect that gluten may be the culprit behind your own digestive issues, consider speaking with a healthcare professional for further guidance and testing.
