What is considered extremely low birth weight?

• A. Less than 1500g
• B. Less than 2000g
• C. Less than 1000g
• D. Less than 2500g

Answer: (C)

Extremely low birth weight is defined as a birth weight of less than 1000 grams (about 2 pounds, 3 ounces). This classification is crucial in perinatal medicine because extremely low birth weight infants are at a significantly increased risk for a variety of complications, such as respiratory distress syndrome, intraventricular hemorrhage, and long-term developmental challenges. The categorization of birth weights allows healthcare professionals to identify infants who may require specialized care and interventions. While other thresholds for low birth weight classifications exist—such as low birth weight (less than 2500 grams) and very low birth weight (less than 1500 grams)—extremely low birth weight represents the most severe category in terms of weight and associated health risks.
