Your son's story is identical to my son's story, so I'll give you run down of how things will go for you both (I say with tongue in cheek, because as parents, we want to KNOW what will happen, but every child is different and encounters different things). Logan was diagnosed at 12 also. Always had a cough, doctors said asthma, asthma, asthma...bowel movements were always huge. Large at birth (almost 10 pounds), high percentile in height and weight which declined steadily over time. For the most part, he was really healthy. In elementary school one year, he even got a perfect attendance award. When updating his "asthma" medication, we were walking out the door when the doctor noticed his large fingers- the clubbing, and sent us for a test. Eureka! An answer (with 10,000 additional questions)! He was never hospitalized until he was 16, but had a few rounds of heavy antibiotics each year. Fast forward....he is 20 now, in college making great grades, having a blast in a fraternity, just got back from Spring Break where he was buff and tan and taking care of himself like he should. The trick? He learned he could control his health to a certain extent: he FEELS it when he doesn't do his treatments, so he DOES THEM (yeah, all teenagers skip because there are things they'd rather be doing. But eventually they realize that feeling good allows them to do more). Second tip- he exercises ALOT. Like, he's almost a gym rat. If it's basketball, track, soccer, Ultimate Frisbee, whatever- cardio is king, and keeps them healthy. So if your story falls in line with ours, then yes, I would take it as a good sign that he hasn't been SO sick that he needed more intense treatment until now. I think you're probably safe believing his condition isn't as bad as some others. I know- things can always change for anyone at any time, including my own son, but I just want to give you another mother's stamp of approval that it's okay not to assume the worst. Treatments have improved so much just since Logan was diagnosed (8 years). They are continuing to improve. My problem now is convincing Logan that he's going to live long enough that it wouldn't be a waste to start a retirement fund. Best wishes to you- let him know he has a LOT of control over this, but he has to choose it.
