Summary

The 20-week anatomy scan has become a routine part of modern pregnancy, but is it truly essential, or just another layer of over-monitoring?

After receiving a listener question, Dr. Stu and Blyss dissect the purpose, limitations, and unintended consequences of the anatomy scan. From what providers are actually looking for, to why so many women walk away with more anxiety than answers, this episode challenges the assumption that more information always equals better outcomes.

At the end of the day, the real question isn’t can we look, it’s should we?
