Celiac / Celiac disease

Previously known in Hebrew as "Machalat HaKereset", it is characterized by sensitivity to gluten, the protein found in grains. It can be diagnosed at any age.
Symptoms may include abdominal pain, diarrhea, iron deficiency anemia, early calcium loss, and more. Diagnosis is established by combining a blood test (serology) and a duodenal biopsy taken during a gastroscopy.
