Can gilberts disease cause high alt 78 and ast 50 and bilirubin 1.2 ?diagnosed with fatty liver in july. had us done in jan it showed little fat.

Could be both: Gilbert's disease and fatty liver. Elevated liver enzymes make fatty liver a more likely explanation as bilirubin of 1.2 is within normal limits. See this site for info on gilbert's. http://www.mayoclinic.org/diseases-conditions/gilberts-syndrome/basics/definition/con-20024904.

Not usually: Gilbert's causes a "cosmetic" abnormality in bilirubin (bile pigment) metabolism. Does not cause changes on ast, alt-that reflects mild inflammation of liver cells. Could be due to overweight, needs, alcohol, infection, immune inflammation, other.
