Digestive discomfort after eating bread, pasta, or baked goods can have several causes. For some people, symptoms appear after consuming gluten, a group of proteins found in wheat, barley, and rye. However, gluten sensitivity and celiac disease are not the same condition, and an accurate evaluation begins with understanding the difference.

Gluten sensitivity is a broad term often used for non-celiac gluten-related symptoms. A person may experience bloating, abdominal pain, diarrhea, constipation, fatigue, headaches, or skin discomfort after eating gluten, even when routine tests do not show intestinal damage. Diagnosis usually involves reviewing symptoms, dietary habits, medical history, and the results of blood tests. A gluten-free trial may also help determine whether symptoms improve.

Celiac disease is an autoimmune condition triggered by gluten. When a person with celiac disease consumes gluten, the immune system reacts and may damage the small intestine, interfering with nutrient absorption. Symptoms can range from digestive problems to anemia, fatigue, weight changes, or skin rashes. Diagnosis commonly begins with blood tests for tissue transglutaminase antibodies and total IgA. An IgA deficiency may affect interpretation, so additional testing may be necessary. A gastroenterologist may recommend an intestinal biopsy to confirm the condition when results require further evaluation.

Blood testing should be discussed before starting a strict gluten-free diet, since eliminating gluten can change antibody levels and complicate diagnosis. People with a family history of celiac disease, unexplained anemia, persistent digestive symptoms, or Type 1 diabetes should seek medical advice regarding testing.
