What causes LGA babies?
By far, maternal diabetes is the most common cause of LGA babies. Diabetes during pregnancy causes the mother's increased blood glucose (sugar) to circulate to the baby. In response, the baby's body makes insulin. All the extra sugar and the extra insulin production can lead to excessive growth and deposits of fat, thus, a larger baby.

What Causes Babies to Be LGA?
There can be many reasons for the baby to be LGA. One of the main reasons for the babies to be LGA at birth is if the mother is detected with diabetes. If the mother has a high blood sugar level, then during pregnancy, she can pass on this sugar to the growing foetus. As a result, the baby makes insulin and the extra sugar and insulin lead to faster growth and fat deposit. This is the common cause for larger babies. It also poses a higher risk of having low blood sugar after birth. This is because, after birth, the mother’s blood supply stops, but the baby’s insulin levels are still high.
