A bit of perspective. There is a difference in the standards of care between the US and some in Europe. My approach leans to the European. We start with the fact that the fundamental problem is the biochemical flow between the liver and fat cells. When diet is poorly balanced, over time fat accumulates in the liver and by itself is rather benign but when other chemistries like insulin management begin to degrade you get inflammation which leads to fibrosis and if not stopped, can progress to cirrhosis. Since there is no treatment your tool is diet and the challenge is to avoid anything that stresses the liver and loads up on anything that is protective.
Several members have been asking about exercise lately. The problem for anyone who is obese or ill is that it is so hard to do. When you think about the fact that you have to walk a mile to burn off a single apple it is easy to be defeated by the task. One apple is about 100 calories and to lose a pound you have to burn 3500 calories. Crazy math, people who tell you to lose weight exercising probably don't face the challenges that you are dealing with.
Historically fatty liver was viewed as being mostly benign. The theory was that while liver fat might make the organ vulnerable to other problems it was, after all just normal fat. This view naturally led to medicine focusing on other problems where symptoms existed. I thought that view made little sense if only because fat people died younger but the science wasn't there so that remained the story.
If knowledge is your goal, this is a great place to start.
Part of dealing with liver disease is to understand it. In order to help you, we are working with Armando Hasudungan who produces superb short videos to explain complex medical subjects. We use them throughout the site to help you understand your body and specifically your liver. The first video gives you a view of the liver overall and the following ones focus on details.
