Odds of a Successful Pregnancy
Seana,
Some clinics define "healthy enough" based on BMI, which is related to height and weight. There are varying degrees of what they call "nutritional status." For awhile I was in "nutritional failure" because my BMI was only 19. BMI is calculated by dividing the weight (in kg) by height (in m). The national goal that the CFF hopes to see its patients achieve is for CFers under the age of 20 to have a BMI that is within the 50th percentile of non-CF individuals of the same age. Young women, particularly those who are looking to bear children, should aim for a BMI of 22.
Based on the information you gave about Courtney, she is very underweight, which you already knew. A good rule of thumb for women is that they should weigh 100 pounds for the first 5 feet of height, and 5 pounds for every additional inch. For example, I am 5'5", so by applying this rule I should aim to weigh 100lbs + (5lbs x 5) = 125 pounds. My BMI is only 20.5 at this point, which is why I'm working so hard to gain that additional muscle mass.
Courtney's BMI is only 14.5. That is VERY low, perhaps even dangerously so. I hope that together you, she and the doctors can find a way to bulk her up so that she'll be much healthier and have a better FEV1. I think it's wonderful that she would like to adopt one day. I hope that all the decisions she makes will be made with her health at the forefront.
Caroline, I love it that we're both looking at the numerical data! (So many people don't even want to attempt to tackle it.) I see where you get that 80+%. I'm redoing my mathematical assumptions. Thanks for making me dig deeper! I LOVE that about the forums.
