The exact cause of Sirenomelia is unknown, but it is believed to be caused by a combination of genetic and environmental factors. Possible causes include a disruption in the normal development of the umbilical cord, a vascular disruption in the lower abdomen, or a combination of both. Other possible causes include maternal diabetes, chromosomal abnormalities, and certain medications taken during pregnancy.

Unfortunately, there is no known cure for Sirenomelia. Treatment focuses on managing the symptoms and complications associated with the condition. Treatment may include surgery to separate the fused legs, reconstructive surgery to correct any malformations, and physical therapy to help with mobility. Other treatments may include medications to help with pain, nutrition support, and psychological counseling to help with any emotional issues.
