Celiac disease is an autoimmune condition triggered by gluten. Diagnosis typically begins with blood tests for specific antibodies and may include an intestinal biopsy while the person is still consuming gluten.
Celiac disease is usually diagnosed between age 10 to 40, but its symptoms can show up later in life or as early as infancy. An gastroenterologist explains why it’s important to get the right diagnosis if you’re experiencing symptoms.
