Hi Sara, I too was diagnosed with fatty liver but mine is the non alcoholic type. I too used to drink like a fish in my 20's but I quit when I was 30. I did miss it but don't anymore. I may have cirrhosis. From what I've been reading (and there isn't much about the subject) is that once you develop fatty liver, if you continue to drink or don't change the lifestyle that causes the fatty liver, then it can develop into full blown cirrhosis which is what I'm facing right now. I have an enlarged liver and spleen and the doctor says the enlarged spleen leads him to think I have cirrhosis. He has referred me to another doctor. I started out with metabolic syndrome about 3 years ago, my insulin levels were high so they put me on metformin which has helped a lot. It helped me to get pregnant when I couldn't before because of polycystic ovarian syndrome which is caused by metabolic syndrome. If I hadn't taken the metformin, I would most likely already have diabetes. To answer your question, it is possible for someone your age to have cirrhosis. They are finding it in teens now. If you want to save your life, you should quit drinking. I know, easier said than done but using your grandfather as an example doesn't help you. You are not him. I wish you the best of luck in fighting this disease. If it has been 2 years since your diagnosis, you may want to go back to the doctor see where your liver is now and take your metformin. If you have cirrhosis, the only cure is a liver transplant and if you don't, all you have to do is stop the intake of alcohol which is so toxic to your liver.
