Living with Cryptogenic multifocal ulcerous stenosing enteritis

A rare intestinal disease with scarring and shallow ulcers in the small intestine that can cause blockage and anemia.

Understanding Cryptogenic multifocal ulcerous stenosing enteritis

Cryptogenic multifocal ulcerous stenosing enteritis is a rare intestinal disease with narrowed areas and shallow ulcers in the small intestine.

It can cause chronic or relapsing partial bowel blockage. People may have long-term iron-deficiency anemia from blood loss in the gut, recurrent belly pain, fatigue, swelling, or slow growth. Some have dry eyes and mouth, joint pain, or Raynaud's phenomenon. It can start from childhood to adulthood.

GARD doesn't list a symptom list for this condition. Its summary mentions these:

  • Long-term or recurring bowel blockage
