You doctor can diagnose both using a blood test. An ultrasound or biopsy or ultrasound may be ordered by your physician if you have multiple suspicious blood tests.

My doctor checks me every six months, and sometimes at three month intervals when my numbers get out of whack.

@mark_fugate, I want to extend my hand and say 'Welcome" to the Connect discussion Group. I am happy that both you and your doctor are working together for your best care.
I was monitored regularly by my GI for another liver condition. So I know how important it is to keep up with those screenings and labs. May I ask a question? What does your doctor suggest when your numbers get 'out of whack?

I do much of my own research on those topics with guidance from my doctor. Everyone is different what works for me may not work for anyone else. That being said, I express what I think, she, my doctor, compliments my thoughts with her's, and from that we derive a plan to address my current condition(s). Further, I keep my wife involved which helps immensely. It is far easier for me to maintain a healthy diet when my wife is doing the same.

Making note that everyone is different, requires, at least for me, to proactively research my condition(s). I subscribe to "Diabetes Forecast" which is loaded with information about diabetes and healthy diet.

A book that I am very fond of, and that my wife is reading now, is "What Do I Eat Now"? That book is a great resource for learning to eat healthy. http://www.shopdiabetes.org/1875-What-Do-I-Eat-Now-2nd-Edition.aspx

You can probably find this book at other sources cheaper. I prefer to purchase from ADA because of where the money goes. That is, indirectly to helping me and others.

@mark_fugate, I definitely agree that we, the patients, must take responsibility of our health by being our own advocates. And that includes the research and the inclusion of conversation with our doctors along with the support of spouse and family. It is evident that both you and your wife are receiving the benefits of this effort. (My husband is eating healthier because of my nutritional needs, so we both benefit).
I want to thank you for the book reference, and the link that you have provided!
