Large For Gestational Age (lga)

What is LGA? Large for gestational age is a term used to describe babies who are born weighing more than the usual amount for the number of weeks of pregnancy. LGA babies have birthweights greater than the 90th percentile for their gestational age, meaning that they weigh more than 90 percent of all babies of the same gestational age. The average baby weighs about 7 pounds at birth. About 9 percent of all babies weigh more than 4,000 grams (8 pounds, 13 ounces). Rarely do babies weigh over 10 pounds. Although most LGA babies are born at term (37 to 41 weeks of pregnancy), a few premature babies may be LGA. What causes LGA? Some babies are large because their parents are large; genetics does play a part. Birthweight may also be related to the amount of weight a mother gains during pregnancy. Excessive weight gain can translate to increased fetal weight. 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.

    It was opposite for me. They kept telling me how little she was. Borderline IGUR. 11th percentile. I was induced 4 days early and she was a respectable 6 pounds 15 ounces. About 50th percentile for all her measurements!
    Of course, she was quite little for me. My first two kids were 9 and 8.3 and I didn't have GD with them.

    My daughter was born at 38 weeks and was 8 lbs 2 oz, she was a typical "football player shaped" GD baby. I was on glyburide and my numbers were not very well controlled.....no matter what I did :( My current pregnancy my numbers are controlled much better, but my baby measured 21 weeks at my 19 week scan. But they are not 100% accurate. But I am betting on having another large baby. Pleas this one is a boy, so I expect him to be at least 9 lbs....but I could be wrong.
