The full answer

Symptoms vary widely between people

Celiac disease can produce digestive symptoms like diarrhea, bloating, and stomach pain, but it just as often shows up as non-digestive symptoms: fatigue, headaches, joint pain, skin rashes, or anemia from poor iron absorption. Some people have several symptoms at once; others have almost none at all — see can you have celiac disease without symptoms.

Why the range is so wide

Symptoms depend on how much of the small intestine is affected and how long the condition has gone untreated, which is why celiac disease is often called a “great imitator” — it can resemble IBS, chronic fatigue, iron-deficiency anemia, or migraines before anyone thinks to test for it. If several of these symptoms sound familiar, that overlap is exactly why proper testing matters rather than guessing.

Important context

Individual symptoms, reactions, medical histories, food products, and local labeling rules can vary. Community experiences are not medical evidence.
