Celiac crisis presents as severe acute diarrhea with life-threatening metabolic derangement in a patient with celiac disease. We report a 30-year-old lady who was admitted with one-month history of worsening small bowel-type diarrhea. She developed acute quadriparesis due to refractory hypokalemia. Celiac disease was diagnosed on the basis of positive serology and histological features. She improved with aggressive correction of hypokalemia and gluten-free diet. Celiac crisis is a rare presentation of this heterogeneous disease in adulthood.
