Omphalocele Awareness Day is observed worldwide every January 31, coinciding with the last day of National Birth Defect Awareness Month in the United States. This day was established to educate the public about omphalocele, a rare birth defect where some abdominal organs protrude through a hole in the navel area due to improper development of the abdominal wall during pregnancy. It is typically detected during a 20-week ultrasound. Families of children with omphalocele are encouraged to seek support and resources, and individuals can participate by donating to relevant organizations and using the hashtag #OmphaloceleAwarenessDay on social media. The day aims to provide crucial information and foster community support for those affected by this condition.
