Decreased bone mineral density is a frequent finding in gastrointestinal disease. Factors contributing to this are (1) malabsorption of vitamin D, calcium and possibly vitamin K and other nutrients; (2) treatment with glucocorticoids; (3) inflammatory cytokines in inflammatory bowel disease; and (4) hypogonadism induced by gastrointestinal disease. A low bone mineral density has been reported in (1) patients who have undergone gastrectomy (27-44% with Z-scores of < -1); (2) pernicious anaemia; (3) coeliac disease (8-22% with Z-scores of < -2); (4) Crohn's disease (mean 32-38% with Z-scores of < -1); and (5) ulcerative colitis (mean 23-25% with Z-scores of < -1). Reduced bone mineral density is thus prevalent in these individuals and is compounded by age related bone loss, leading to the development of severe bone disease in some patients.
