Celiac disease is a condition where eating gluten—a protein found in wheat, barley, and rye—damages the small intestine and prevents your body from absorbing nutrients properly. If you or a family member has been diagnosed with celiac disease, or you're trying to understand symptoms like stomach pain, bloating, or fatigue, this section explains what the condition is, how doctors identify it through blood tests and biopsies, and what living with it actually involves.
The articles here answer practical questions: How do you know if you have celiac disease? What happens during testing? What can you eat, and what should you avoid? How do you read food labels and manage meals at home and away? You'll also learn about the difference between celiac disease, non-celiac gluten sensitivity, and wheat allergy—conditions that can feel similar but require different approaches.
