“At my 20 week anatomy scan I was diagnosed with single umbilical artery. It seems to affect 1 in 100 pregnancies. I am so nervous. My doctor said not to worry, but I know there are several risks involved with this diagnosis. I have read that if there are no other issues and it is “isolated”, that there isn’t too much to worry about.  Here are a couple things I’ve read that I would like to confirm and learn more about. First most of the growth issues with SUA babies don’t appear until later in pregnancy. Second there seems to be an increased need for C-section or early induction due to doctors being concerned with stress on baby’s heart. Any info would be really helpful.” – Monica
