Y wud i hav nash or nafld if i am a 24 y male non alcoholic bmi 19.5. exellent lipid profile. good mediterranean diet.negative u/s & workup 4 high alt?

A few ideas: I trust this is not hepatitis c; this can mimic NASH including the fat. We're puzzling out the fatty liver stuff and some of it seems hereditary; you've probably caught on that there's no consensus on treatment of folks like you, but you may want to think about seriously increasing your aerobic fitness stuff for your own sake and your liver's. Good luck.

NAH: I'm not sure one abnormal liver function test would qualify as adequate to label one with a diagnosis of hepatic disease. Have you discussed with your dr.? Have you seen a gastroenterologist?
