Provided herein are variants of fibroblast growth factor 19 (FGF19) proteins and peptide sequences (and peptidomimetics) and fusions of FGF19 and/or fibroblast growth factor 21 (FGF21) proteins and peptide sequences (and peptidomimetics), and variants of fusions of FG-F19 and/or FGF21 proteins and peptide sequences (and peptidomimetics). In some embodiments, these variants and fusions modulate bile acid homeostasis, and are useful in treatment of bile acid related and associated disorders. In some embodiments, these variants and fusions have glucose lowering activity, and are useful in treatment of hyperglycemia and other disorders.
