I am a male with normal weight. I do not drink alcohol but I have a habit of cannabis smoking. It did it for a couple of years with short intermittent pauses for two to three weeks. I started to have symptoms of jaundice, diarrhea, and fatigue at the end of the month. I do not had any other previous symptoms on that month. I do not have any other diseases. My transaminase was normal and it was checked during the routine blood work. I have attached the reports. I did an abdominal CT with contrast and the result was normal. Plasmapheresis was done and a liver function test was also done. I had an AST of 800, ALT of 450, and total bilirubin was 12 mg/dL. After three days, I had an AST of 1010, an ALT of 505, and had total bilirubin of 14 mg/dL. During this period, I had a weight loss of 10 to 15 kilograms and my appetite was normal. I want to know my differential diagnosis and prognosis. Please suggest.
