Celiac disease and non-celiac gluten sensitivity are complex conditions that often require the involvement of multiple healthcare professionals for accurate diagnosis and appropriate treatment. If you experience gastrointestinal discomfort or symptoms that suggest a reaction to gluten, the first point of contact should be your primary care provider. From there, a series of tests and referrals to specialists may follow to ensure a proper diagnosis and care plan.

The Role of Primary Care Providers

When symptoms like bloating, diarrhea, fatigue, skin rashes, or brain fog become persistent and appear related to food, especially gluten-containing products, it’s crucial to seek medical advice. Primary care providers are typically the first to evaluate your symptoms. They will take a detailed history, perform a physical examination, and likely recommend initial blood tests to look for indicators of celiac disease.

One of the standard tests is a panel that looks for specific antibodies in your blood. These antibodies are often elevated in individuals with celiac disease. However, for these tests to yield accurate results, you must be consuming gluten-containing foods at the time of testing. It's essential not to start a gluten-free diet before these tests are conducted, as doing so could produce false-negative results.

If the results of the blood tests are positive or inconclusive, your provider will generally refer you to a specialist known as a gastroenterologist for further evaluation.

Why You May Need a Gastroenterologist

Gastroenterologists specialize in diagnosing and managing diseases related to the digestive system. For patients suspected of having celiac disease, a gastroenterologist plays a central role in confirming the diagnosis. The most common next step is an endoscopy with biopsy.

During this procedure, a flexible tube with a camera is passed through your mouth into your small intestine. The gastroenterologist will collect small tissue samples from the lining of your small intestine, which are then analyzed to check for typical changes associated with celiac disease, such as villous atrophy (damage to the finger-like projections in the small intestine).

The Role of the Pathologist

The biopsy samples obtained during the endoscopy are sent to a pathologist. This medical specialist examines the tissue under a microscope to look for damage consistent with celiac disease. Some of the hallmarks they search for include:

  • Flattening of the villi in the small intestine

  • An increase in inflammatory cells such as lymphocytes

The classification of the findings may follow a system known as the Marsh Classification, which helps determine the severity of intestinal damage. This helps guide the treatment plan.

What Comes Next After Diagnosis

If you are diagnosed with celiac disease, the gastroenterologist or your primary care provider will guide you through the early steps of management. Follow-up care includes regular monitoring of nutritional status, repeat antibody testing to assess compliance and effectiveness of a gluten-free diet, and managing any associated symptoms or complications.

If testing does not confirm celiac disease, and you still experience symptoms when consuming gluten but feel better on a gluten-free diet, your doctor might explore the possibility of non-celiac gluten sensitivity (NCGS).

Understanding Non-Celiac Gluten Sensitivity

Non-celiac gluten sensitivity shares many symptoms with celiac disease but lacks the characteristic intestinal damage and immune markers seen in celiac disease. People with NCGS typically have negative blood tests and normal biopsy results but still experience improvement in symptoms when avoiding gluten.

The management of this condition differs slightly—it still requires dietary changes but doesn't necessarily involve the same level of medical monitoring or risk of complications as celiac disease. That said, working with medical professionals and a dietitian is essential to rule out other causes and ensure nutritional adequacy.

Other Specialists Who May Be Involved

Depending on your specific symptoms and any complications, you may need additional specialists as part of your care team:

  • Neurologists: If you experience migraines, neuropathy, or other neurological symptoms that could be linked to gluten-related disorders.

  • Dermatologists: For skin conditions such as dermatitis herpetiformis, a rash strongly associated with celiac disease.

  • Endocrinologists: If you also have autoimmune conditions like diabetes or thyroid disorders, which are more common in those with celiac disease.

  • Gynecologists or Fertility Specialists: Celiac disease can sometimes interfere with reproductive health, and consultation with specialists in this field may be needed.

  • Dietitians: A crucial part of managing both celiac disease and gluten sensitivity is a lifelong gluten-free diet. A registered dietitian can help you learn how to read labels, plan balanced meals, and avoid nutritional deficiencies.

Ongoing Management and Monitoring

Even after diagnosis and initial dietary changes, ongoing management is important. Your healthcare team may monitor your vitamin and mineral levels, as people with celiac disease are at higher risk of deficiencies in iron, B vitamins, calcium, vitamin D, and others. Bone density testing may also be recommended, especially if diagnosis was delayed or symptoms were severe.

In addition, you may need emotional or psychological support as you adjust to a new lifestyle and dietary restrictions. Many people find joining support groups or working with a mental health professional helpful.

Conclusion

Managing celiac disease or non-celiac gluten sensitivity involves a coordinated effort among various healthcare providers. From primary care practitioners who initiate testing, to specialists like gastroenterologists, pathologists, and dietitians, each plays a vital role in ensuring a proper diagnosis and effective treatment plan.

Understanding the range of professionals involved and the steps in diagnosis and care empowers you to take control of your health. With accurate diagnosis, proper guidance, and a commitment to dietary changes, most individuals with gluten-related disorders can achieve significant symptom relief and long-term well-being.
