SOURCE: Medical News Today

DATE: April 21, 2009

EXCERPT: "The present analyses showed a positive association between DM and gallstone disease in men but not in women and hypertriglyceridemia or obesity only showed a positive association with gallstone disease in women. There were disparate findings about DM, hypertriglyceridemia and obesity in different sexes with gallstone. These results demonstrate men have a different metabolic character from women in gallstone disease patients, which may provide more information for
investigating the true pathological mechanism of gallstone disease."   more
