Treatment
Another experimental approach to treatingNASH is the use of newer antidiabetic It is important to stress that there are cur- rently no specific therapies for NASH. The insulin resistance, meaning that the insulin normally present in the bloodstream is less effective for them in controlling blood glu- cose and fatty acids in the blood than it is for people who do not have NASH. Thenewer antidiabetic medications make the body more sensitive to insulin and may help reduce liver injury in patients with NASH.
