To the person who posted last, I'm glad that you took steps to inform yourself. That's a wonderful thing, and I appreciate your comments. If your research hasn't told you yet, CF is the NUMBER ONE genetic "killer" of children and young adults. It is the most common caucasion genetic defect (although it exists in all races) and something like one in twenty caucasions are carriers of the gene. We tend to get so frusturated because the disease is MUCH more common than anybody thinks and nobody seems to be very well informed about it.Also, "symptoms" are very individualized and just because a person does not show symptoms does not mean that their body does not need matainence. You might not have noticed, but Frankie's fingers are rounded at the tips. This is called clubbing and means that there is chronic lung infection. Did you notice how round her rib cage is? It's called a barrel chest and is also a sign of lung problems. We have to take medicine every day, and do lung therapy every day just to keep our selves "normal". We don't just take meds when we're sick.Please continue to chat with us!Debbie22 yr old w/ CF
