<s>[INST] Hi, I am feeling nauseated with 2 vomit episodes in the last 16 hrs, 2 hours prior my symptoms, I ate pork (it was a bit too greasy), I had blood test done and it says that my liver enzymes were slightly elevate, AST 94, and ALT 54, can you please inform me what is the meaning of such values? [/INST] HI, thanks for using Chat Doctor The main causes of increased liver enzymes are: (1) non-alcoholic liver disease-this is liver disease not related to alcohol use. Occurs in persons with increased weight, decreased activity, poor diet, diabetes, history of high cholesterol(2)alcohol use(3) infection(4)trauma(5)side effect of medication such as statins related to alcohol or medications, discontinuation would help. If due to infection then treatment of the infection is needed. If due to non-alcoholic liver disease then lifestyle changes would be important. The episodes of vomiting may be related to the food used since you stated it was a little greasy. I hope this helps </s>
