38 views

While rare, a twin can go unnoticed during early stages of pregnancy due to factors like low-resolution ultrasound equipment or the positioning of the fetuses. This phenomenon is known as vanishing twin syndrome, where one twin is not detected on subsequent ultrasounds. Consistent prenatal check-ups are crucial for correct diagnosis and management.

FAQs & Answers

  1. What is a vanishing twin syndrome? Vanishing twin syndrome occurs when one twin is not seen during later stages of pregnancy despite being initially detected. This can happen due to various reasons, including miscarriage of one twin.
  2. Can low-resolution ultrasound equipment miss a twin? Yes, in the early stages of pregnancy, low-resolution ultrasound equipment may not be able to detect both twins if they are positioned in a way that makes one difficult to see.
  3. How often should I have prenatal check-ups if I'm having twins? Expectant mothers of twins should have more frequent prenatal check-ups, typically every two weeks after 28 weeks of pregnancy, to monitor the health of both babies.
  4. What are the signs of carrying twins? Signs of carrying twins can include more pronounced pregnancy symptoms, such as weight gain, extreme fatigue, and more significant fetal movement. However, an ultrasound is needed for a definitive confirmation.
