Conjoined twins

Updated: 2017-06-13

Overview

Conjoined twins develop when an early embryo partially separates to form two individuals. Most conjoined twins are stillborn or die shortly after birth.

Symptoms

The babies are often attached at the chest, pelvis, or buttocks. The twins may share organs.

Treatments

Surviving twins may be separated surgically. Success depends on where they're joined and which organs they share.
