Im very sorry to hear about this.
HOWEVER, I CAN TELL YOU THERE IS HOPE!!!
i am a 33 year old male with CDH... This was not seen on any ultrasounds. in fact, this was discovered purely by accident whilst they were removing my gallbladder.
This is a rare and worrying condition. But i survived 30 years with it (it was found on my 30th birthday). There are, to my knowledge, 2 types of CDH. I have the WIDE NECK Hernia. Which tends to be less troublesome.
i cannot tell you that everything will be alright when she is born. i am not a doctor, surgeon or midwife. BUT, i can tell you, that it MAY NOT necessarily impact her life to the point where she will need care for the rest of her life. It may just impact her ability to do sports.
i have no REAL lung issues. I have had Asthma since i was a child and my lungs have been able to grow perfectly.
Please try to relax, have a safe birth, and let the doctors do what they can.
There is hope. You're talking to someone who in all probability has beaten the odds of winning the lottery 10 times in a row. XX
