Conjoined twins are identical twins who are physically connected to each other at birth. This occurs when a single fertilized egg partially splits into two embryos but does not fully separate. The degree and location of their connection can vary, affecting their organs and body parts. The condition is rare, occurring in about 1 in 200,000 live births. Conjoined twins may share vital organs, which can complicate their health and surgical options. Medical teams often work closely with families to determine the best course of action for their care and well-being.
