Winner of a video, I've been looking for "foods to eat to reverse fatty liver" for a while now, and I think this has helped. Have you heard people talk about - Jeyebastian Venlena Blaster - (do a search on google ) ? Ive heard some super things about it and my colleague got great results with it.

As an emergency medicine PA-C, with plans to go into academia later in my career, I appreciate your videos for review of general medical knowledge. The videos are engaging and the material is very well explained. I've directed PA students of mine to your videos to help them in their studies and to help understand laboratory and physical exam findings while on their clinical rotations with me. Keep up the great work! Your videos are invaluable to me.

I totally agree with you. We had a whole semester of clinical lab medicine course. The lectures were no where near Dr. Seheult's explanation. The classes were a waste of time and left us with confusion. Only with Dr. Seheult's lecture I am able to understand the concept better.

Thanks for the video, its great and i have a clear concept on LFT now. just wanted to make some corrections. If i am wrong let me know: -gilbert syndrome is autosomal recessive (not dominant) -Extravascular hemolysis causes an increase in Indirect bilirubin. (not intravascular. intravascular causes hemoglobinemia and hemoglobinuria. extravascular hemolysis results in breakdown of the heme into unconjugated bilirubin)
@Medcram
@Medcram 8 лет назад

I had jaundice almost 2 years from now i went for a proper medical checkup and did every thing to cure it . I avoided oily and fatty foods. I only ate salads. I took every medicine until the tests showed Normal. But then when I repeated the test a month after it again showed bilirubin out of the normal range.This hapenned many times that year and in the end Doc. said that" you have Gilberts Syndrome...and all of this is normal for people wth GS." For now I am assuming that I have Gilberts synd. Moreover, what i realize is that the bilirubin level in my blood increases whenever i have an illness like fever or headache ,stress(during exams),during fasting (in the month of ramadhan).Now i want to know if I really have GS or not and i will be so glad if You help me in this.

Do I need to fast before a liver function test? I fasted for 12 hours before a liver function test 3 weeks ago and my ALT was 57. Today I didn't fast and my ALT was 114! Is this because I didn't fast? I haven't had any alcohol, and am eating a very clean diet for the last 3 weeks.

@jamesmueller4943
@jamesmueller4943 8 лет назад
Hello, I know you can't diagnose anything, but I would really respect your opinion. My ALT is 113 (normal is 10-63) AST and ALP normal. Had an ultrasound done, came back showing a mildly enlarged spleen at 13.47cm, and my liver is showing fatty liver. It also showed bile ducts were normal. All my CBC is normal. My Total bilirubin is 3.2 (normal is 1.5), and direct being 0.3 (normal). So that means my indirect is causing my high bilirubin. LDH was actually a little low at 100 (normal was 120-250). Since hemolysis is pretty much ruled out, do you think this is a case of Gilbert's Sydrome?
