Question
Hello doctor,
This year, I am 36 years old, 33.5 weeks pregnant. I went for an ultrasound of the fetus, concluded that there was a 12mm dilated bowel loop, the doctor advised to continue to monitor. I am very worried, do not know the reason why and if it will affect the baby, will the baby be born with any dangerous diseases in the future. I hope the doctor can advise me on the cause of 12mm dilated bowel loops in the 34-35 week fetus?
