Celiac disease: symptoms and effects

How celiac disease presents — classical, extraintestinal and asymptomatic forms. Educational overview based on WGO guidelines.

Celiac disease is a lifelong autoimmune reaction to gluten. Its presentation varies widely — from classical malabsorption to “hidden” extraintestinal signs.

Classical form (with malabsorption)

Adults: chronic diarrhea, weight loss, iron-deficiency anemia, abdominal distension/bloating, malaise and weakness, edema (hypoproteinemia), osteoporosis.

Children: failure to thrive, weight loss and growth retardation, vomiting, chronic diarrhea, bloating, iron-deficiency anemia, loss of muscle mass, edema, irritability and low mood.

Non-classical form — extraintestinal & associated manifestations

Asymptomatic form. Up to ~50% of newly diagnosed cases have no complaints despite characteristic intestinal changes; these are often found through screening.

This is educational information, not a diagnosis. If you suspect celiac disease, see a physician and do not remove gluten from your diet before testing — it will distort the test results.
