Overview[edit | edit source]

Celiac disease must be differentiated from other diseases presenting as chronic diarrhea. Common differentials of celiac disease include lactose intolerance, cystic fibrosis, Crohns disease, laxative overuse, hyperthyroidism and irritable bowel syndrome.

Differentiating Celiac Disease from Other Diseases[edit | edit source]

Celiac disease must be differentiated from other diseases presenting as chronic diarrhea (diarrhea for more than 2 weeks) and abdominal pain and discomfort.^[1]^[2]^[3]^[4]^[5]^[6]^[7]

The table below summarizes the diseases that cause malabsorption, diarrhea and abdominal pain.
