Intrauterine Growth Restriction Awareness Day, observed worldwide every March 13, aims to highlight the medical condition known as intrauterine growth restriction (IUGR), which affects approximately 3% of pregnancies. IUGR is characterized by poor growth in unborn babies, leading to lower than normal weight for their gestational age and potential long-term health issues. The day encourages individuals to learn about IUGR, share information on social media using the hashtag #IUGRAwarenessDay, and support related charities. It is important to note that IUGR Awareness Day differs from World SIUGR Awareness Day, which focuses on selective intrauterine growth restriction affecting one twin in cases of multiple pregnancies. Observers may also consider sharing personal experiences to foster a sense of community among those affected by the condition.
