Personally, I would want another biopsy if I had not had one in 6 years.
Liver damage progresses at different rates in different people. Some people have gone from Stage 2 to Stage 3 or 4 in only 3 years or so. So I would definitely want to know what stage I was at now before starting treatment.
If you don't think the GI is qualified, can you ask for a Hepatologist?
Fatty foods:
I ate a lot of regular Greek yogurt, eggnog, cheese (2 ounces of Cheddar or Havarti is 20 grams), avacado (1 medium has at least 20 grams), bratwurst (cannot remember how many, read the label), cream cheese, ice cream, peanut butter (read label), nuts. If I thought I was eating something without enough fat or was not sure, I added 20 grams of fat with butter, mayo, heavy whipping cream so I was sure to get 20 grams. I always ate some solid food. Toast and the Greek yogurt, egg and toast and the eggnog, toast or bread with the ice creame if I had ice cream at 10 pm. You need some bulk in the stomach as well as the fat so drinking 20 grams of fat via olive by itself won't do the trick. If you eat nuts eat something else too, for bulk. I used to eat chicken soup and saltimes and then add something with 20 grams of fat like berries with a lot of heavy whipping cream on them. You have to get a little creative because food is not going to taste the same as it does not. Sometimes nothing was appealing. I also found myself stocking up on cheese and avacados, only to find that I could not stand eating them the following week. Another thing I did was add some condiments to the plate to make food taste like something besides cardboard. I would have meat and add a bunch of greek olives or herbed olives or pickled beets or plain pickles as a side to help get the meat down. It worked.
I am going to try to find a link to another thread. I should have bookmarked it, lol: This link has some good ideas in it for fatty foods. Scroll down to 80mecheng's very long post with many, many foods to choose from.
