Neonatal Complications: What is Very Low Birth Weight?

Obie Editorial Team
Welcome to a team effort in understanding and addressing very low birth weight in newborns. When an infant is born weighing less than 2,500 grams, or 5.5 lbs, they fall into the category of low birth weight. Slightly more than 8% of infants are born low birth weight. Of these, some weigh less than 1,500 grams or 3.3 lbs at birth. This is what we refer to as very low birth weight. While both categories involve risks and challenges, they differ significantly in various aspects of health and healthcare. Let's delve into how you can navigate this journey with confidence and knowledge.
Approximately 1.5% of infants are born with very low birth weight, and understanding the causes is crucial. Recent years have seen an increase in multiple pregnancies, which is a contributing factor. Many of these infants are premature, arriving before the 30th week of gestation. Intrauterine growth restriction is another concern that can limit fetal growth and often leads to premature delivery. Acknowledging these causes allows us to better understand and prepare for the medical care that will be necessary.
Infants born weighing less than 3.3 lbs generally exhibit specific characteristics. They often appear extremely underdeveloped with a noticeably thin body and minimal body fat, as fat accumulation primarily occurs in the third trimester. Their heads might appear disproportionately large compared to their bodies. The skin may seem transparent due to visible blood vessels, and their organs, including the lungs, tend to be underdeveloped. These infants will need advanced and sustained hospital care, but their situation is one that we can manage actively and optimistically.
Being born at a very low birth weight poses certain challenges, but let's address these proactively. Premature birth increases the risk of complications such as infections, breathing difficulties, temperature regulation issues, and gastrointestinal problems. Time in the neonatal intensive care unit is often required to provide the specialized care needed for these infants to thrive. While long-term health concerns like deafness, blindness, cerebral palsy, and other developmental disorders are possibilities, knowing these risks helps us prepare and support the infant as best as possible.
It's important to focus on the advancements in medical science that have improved survival rates significantly for very low birth weight infants over the years. With dedicated medical attention, specialized nutrition, and continuous care, these infants can flourish. As part of the team supporting these infants, you'll get comprehensive education about potential long-term concerns while they receive hospital care. Overall prognosis is influenced by factors such as gestational age at birth, organ development, and any complications encountered after birth. While these infants are at an increased risk for premature death, being informed equips you and your healthcare team to provide the best possible care and outcome for your infant.
