Again, only my opinion.... while AA can be genetic, that still isn't a 100% that you will have it too. That's a little unfair to saddle you with that weight. However, being prepared is always a good thing. And having an AA isn't a death sentence, it's about understanding the condition and being monitored. For women in non child barring years, 5.0 is the typical measurement for surgery. If there is a possibility for pregnancy, they usually recommend surgery at 4.5. Or at least in my congenital clinic, that's the case.
I am the main caregiver to my father. He's a type II diabetic, has had a major stroke and heart attack, with a CABG x 5. He won't listen to a darn thing I say. I took the time to make sure he had the tools he needed and educated him the best I could on his conditions and what he can do to get and stay healthy. Arranged nutritionists and social workers to help me talk to him. I ask his doctors to talk to him at every appt and I sit there and make sure they talk about diet and exercise. But other than that, he has to make his own choices and he WILL NOT listen to me. And he still eats hot dogs and drinks sodas all the time :)
Sometimes you just have to let it go...... I don't think parents like listening to their children.
