  • Clinical symptoms including chronic diarrhea and steatorrhea
  • Evidence of malabsorption (weight loss, nutritional deficiencies)
  • Laboratory findings showing vitamin B12 or folate deficiency
  • Small bowel biopsy findings consistent with tropical sprue
  • Response to antibiotic therapy or nutritional supplementation
