Gluten Sensitivity: Signs, Tests, and What Actually Helps
Think gluten makes you feel off but doctors say you don't have celiac disease? You might be dealing with non-celiac gluten sensitivity (NCGS). It’s real for some people, and the right approach stops the guesswork and helps you feel better fast.
So how does NCGS show up? Common signals include bloating, stomach pain, diarrhea or constipation, headache, brain fog, tiredness, joint aches, and mood swings after eating wheat, barley, or rye. Symptoms often start hours or a day after eating gluten and improve when you avoid it. If these things match your experience, keep reading—there are clear steps you can take.
How doctors tell the difference
Don’t self-diagnose by cutting out gluten first. If you stop gluten before testing, doctors can’t check for celiac disease accurately. The usual route: your doctor will test for celiac with a blood test (tTG-IgA) and may recommend an intestinal biopsy if needed. If tests come back negative and wheat allergy is ruled out with allergy tests, NCGS becomes more likely. Research reviews put NCGS prevalence roughly between 0.5% and 6%—not everyone who feels better off gluten actually has it, so testing matters.
What to do next: practical steps
1) Get tested before you remove gluten. That keeps celiac disease from being missed. 2) If tests are negative and your doctor thinks NCGS is possible, try a short supervised trial: a structured gluten-free period of 2–6 weeks, then a controlled reintroduction to see if symptoms return. Keep a simple food and symptom diary—note portion sizes and timing. 3) Focus on a balanced gluten-free plan. Many people go gluten-free and end up eating more processed foods. Choose naturally gluten-free whole foods: fruits, vegetables, lean proteins, rice, potatoes, quinoa, and legumes. 4) Watch for hidden gluten in sauces, processed meats, and supplements. Read labels and ask in restaurants about cross-contact.
Need help staying balanced? A registered dietitian who knows about gluten issues can create a safe, varied eating plan and suggest supplements if you’re missing nutrients like fiber, iron, or B vitamins.
When should you see a specialist? If you have unexplained weight loss, persistent severe stomach pain, blood in stool, or symptoms that don’t improve with a proper trial, ask for a gastroenterology referral. Also get rechecked if your symptoms change.
Living with gluten sensitivity doesn’t have to be stressful. With proper testing, a short elimination process, and a focus on whole foods, most people find clarity and better health.
