Everyone should be concerned about their health at all times. I've had elevated liver enzymes, so I'm watching my weight and diet, and limiting the alcohol. Once a health issue arises, it can be a nagging condition for the rest of your life. Listen to your docs, and keep up the healthy lifestyle. Another cause for liver problems could be using acetominophen....don't take too much (or none at all). Unfortunately, it takes a health crisis to get most people off their butts and into the gym or health food store. I wouldn't worry about it too much, but then again, the times of partying and binging are all over. I've known people with diabetes, cancer, other health issues who have lived well into their 90's once they actually started taking care of themselves. Good luck!
BTW, what were your levels, and did you have pain/discomfort on your right side?
