Large for gestational age (LGA) refers to a birth weight or length that significantly exceeds the average for babies of the same gestational age. The term is typically used when the estimated weight is above the 90th percentile for gestational age.
Definition[edit]
The definition of LGA varies depending on the specific growth chart used. However, it is generally defined as a weight, length, or head circumference that lies above the 90th percentile for that gestational age. This means that the baby is larger than 90% of all other babies of the same gestational age.
Causes[edit]
Several factors can contribute to a baby being LGA. These include gestational diabetes, genetic factors, and certain medical conditions. In some cases, the cause is unknown.
Gestational diabetes[edit]
Gestational diabetes is a condition in which a woman without diabetes develops high blood sugar levels during pregnancy. This can result in the baby growing larger than usual.
Genetic factors[edit]
Certain genetic factors can also contribute to a baby being LGA. For example, if the parents are tall, the baby is more likely to be large for gestational age.
Medical conditions[edit]
Certain medical conditions, such as Beckwith-Wiedemann syndrome, can also result in a baby being LGA.
Complications[edit]
Babies who are LGA are at increased risk of certain complications, including birth injuries, hypoglycemia, and jaundice. They may also be at increased risk of obesity and type 2 diabetes later in life.
Management[edit]
Management of LGA may involve careful monitoring of the baby's growth and development, as well as management of any underlying conditions, such as gestational diabetes.
