For people living with celiac disease in Northern Virginia, everyday foods that most people never think twice about can quietly cause real harm. Celiac disease is an autoimmune condition in which eating gluten, a protein found in wheat, barley, and rye, prompts the immune system to damage the lining of the small intestine. Because the symptoms can look like many other digestive problems, it often goes unrecognized for years. This guide explains the common signs, why testing should come before any change to your diet, how the diagnosis is made, and how care works once you have answers.
This article is general education, not medical advice. Your symptoms should be evaluated by a physician who can consider your full history.
What celiac disease is
Celiac disease is a long-term autoimmune disorder, not a food allergy or a simple intolerance. When someone with celiac disease eats gluten, the immune system reacts by attacking the small intestine, where the body absorbs nutrients from food. Over time this can flatten the tiny, finger-like projections called villi that line the intestine, which makes it harder to absorb the vitamins and minerals you need. According to the National Institute of Diabetes and Digestive and Kidney Diseases, celiac disease affects roughly 1 in 100 people worldwide, and many of them do not yet know they have it.
Common symptoms of celiac disease
The symptoms of celiac disease vary widely from one person to the next, which is part of why it can be hard to spot. In adults, digestive symptoms can include diarrhea, bloating, gas, abdominal pain, and constipation. Just as often, the signs show up outside the gut. People may notice fatigue, unexplained weight loss, iron-deficiency anemia, bone or joint pain, headaches, mouth ulcers, or an itchy, blistering skin rash known as dermatitis herpetiformis. In children, celiac disease can affect growth and development. Because this range is so broad, some people have it for years before the pieces come together.
Celiac disease versus gluten sensitivity
It is easy to confuse celiac disease with other reactions to gluten, but they are not the same. Celiac disease is autoimmune and causes measurable damage to the small intestine. Non-celiac gluten sensitivity, by contrast, can cause similar symptoms such as bloating or fatigue, but it does not trigger the same immune attack or intestinal damage, and it is diagnosed differently. A wheat allergy is something else again, an allergic response to wheat proteins. These distinctions matter because the testing, the risks, and the long-term care are different. That is one reason a gastroenterologist tries to identify exactly what is going on rather than treating every reaction to gluten as the same thing.
Why testing should come before going gluten-free
This is the single most important point for anyone exploring celiac disease in Northern Virginia. Do not start a gluten-free diet before you are tested. Both the blood tests and the intestinal biopsy used to diagnose celiac disease rely on your body still being exposed to gluten. If you remove gluten first, the tests can come back normal even when the disease is present, which can delay an accurate diagnosis. The Celiac Disease Foundation notes that you should continue eating gluten until testing is complete. If you have already cut out gluten, let your physician know, because there are ways to plan testing around that.
How celiac disease is diagnosed
Diagnosis usually happens in two steps. The first is a blood test that looks for specific antibodies the immune system produces in response to gluten, most commonly the tissue transglutaminase antibody, often called tTG-IgA. If that result suggests celiac disease, the next step is typically an upper endoscopy with a biopsy. During this short outpatient exam, a gastroenterologist passes a thin, flexible camera through the mouth to the small intestine, usually under sedation, and takes small tissue samples. Examining those samples is how a physician confirms whether the intestinal lining has been damaged. Together, the blood work and the biopsy give a clearer picture than either one alone.
What happens after a diagnosis
There is no medication that reverses celiac disease, and the main approach to care is a lifelong gluten-free diet. Removing gluten allows the small intestine to heal in many people and can ease symptoms over time, though healing can take months to longer and varies from person to person. Working with a gastroenterologist, and often a registered dietitian, helps you learn how to read labels, avoid hidden sources of gluten, and address any nutritional gaps such as low iron, calcium, or certain vitamins. Your physician may also recommend follow-up visits to track how you are doing and to check whether the intestine is recovering. Care is individualized, and what works for one person may look different for another.
When to talk with a gastroenterologist
It is reasonable to see a gastroenterologist if you have ongoing digestive symptoms, unexplained anemia or fatigue, or a close family member with celiac disease, since the condition tends to run in families. Symptoms that overlap with other conditions, such as those of irritable bowel syndrome, are worth sorting out rather than guessing at, because the right diagnosis points to the right care. A physician can review your history, order the appropriate tests while you are still eating gluten, and explain what your results mean. You can learn more about the condition from the National Institute of Diabetes and Digestive and Kidney Diseases and the Celiac Disease Foundation.

Frequently asked questions about celiac disease in Northern Virginia
Should I go gluten-free before getting tested for celiac disease?
No. The blood tests and intestinal biopsy used to diagnose celiac disease depend on your body still being exposed to gluten. Going gluten-free first can make the tests appear normal even when the disease is present, so it helps to keep eating gluten until testing is complete.
How is celiac disease diagnosed?
Diagnosis usually starts with a blood test that checks for specific antibodies, such as tTG-IgA. If that suggests celiac disease, a gastroenterologist typically confirms it with an upper endoscopy and a small biopsy of the small intestine.
Is celiac disease the same as gluten sensitivity?
No. Celiac disease is an autoimmune condition that damages the small intestine when you eat gluten. Non-celiac gluten sensitivity can cause similar symptoms but does not involve that immune attack or intestinal damage, and it is diagnosed differently.
How is celiac disease managed?
The main approach is a lifelong gluten-free diet, often with support from a gastroenterologist and a registered dietitian. Removing gluten allows the intestine to heal in many people over time, and follow-up visits help track recovery and address any nutritional gaps.
