Recent studies have shown that a relationship between fetuin B and glucolipid metabolism, the aim of this review is to summarize the development of the studies, better elucidate the physiological role of fetuin B, as well as provide the new conceptions on prevention, diagnosis, and therapy of metabolic disorders.
