Newborn Baby birth weight | ||||||
- During a normal pregnancy your baby will grow and develop at about the same rate as any other pregnancy. When you visit your Doctor, midwife or other health care provider for antenatal care they will check you over, your weight, heart rate.They may also measure your abdomen on the outside to check your baby's size and rate of growth. This measurement is taken from the upper edge of the pubic bone to the top of the uterus and is called the fundal height. If there is an unexplained discrepancy between size and dates, your care provider could arrange an ultrasound to determine the cause. But try not to be concerned. The most likely explanation is that everything is quite normal and that there is no need to worry. If the size is greater than dates, it may indicate twins, a large baby, or even mis-measuring. Doctors are more concerned when the fundal height is too small rather than too large, as this could indicate that the baby is not growing properly. This can be confirmed with a series of ultrasounds that monitor how quickly the fetus is growing. In some cases, fetal growth can be improved by treating any condition in the mother (such as high blood pressure) that may be a contributing factor.

Low Birth Weight (LBW) or (SGA) | ||
Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age. One third of babies born with a low birth weight are also small for gestational age.Other definitions include Very Low Birth Weight (VLBW) which is less than 3 lb 5 oz (1500 g), and Extremely Low Birth Weight (ELBW) which is less than 2 lb 3 oz (1000 g). About 10 percent of fetuses are low birth weight. A health care provider may suspect fetal growth restriction if the mother's uterus measurement (fundal height) is lower than expected. This can be confirmed with a series of ultrasounds that will monitor how quickly the fetus is growing. Measurements can be taken of the fetus' head and limbs and compared with a growth chart to estimate fetal weight. In some cases, fetal growth can be improved by treating any condition in the mother (such as high blood pressure) that may be a contributing factor. The health care provider will closely monitor the well being of a growth restricted fetus using ultrasound and fetal heart rate monitoring. If these tests show that the baby is having problems, the baby may need to be delivered early. The main causes for Low Birth Weight: The two main causes of LBW are early delivery, also known as preterm birth, and poor fetal growth. About 70% of all LBW babies are born preterm - before 37 completed weeks of pregnancy. The remaining 30% of low birth weight babies are born at full term, but did not grow properly in the womb. Preterm Birth ~ Some of the risk factors for preterm birth are:

Large for Gestational Age (LGA) | ||
The average newborn weight is about 7 pounds 8 ounces (3,400grams). The term macrosomia is used to describe a newborn with an excessive birth weight, which literally means "large body". The diagnosis of fetal macrosomia can be made only by measuring birth weight after delivery. Fetal macrosomia has been defined in several different ways, including birth weight of 8 lb 13 oz to 9 lb 15 oz (4000-4500 g) or, greater than 90% for gestational age. High birth weight (HBW), babies weighing over about 9 pounds (4,080g) fall into the 90th percentile for weight and are known as large for gestational age (LGA) babies. About 10 percent of all babies weigh more than 8 pounds, 13 ounces (4 kg). With about 1.5% of babies their birth weight was equal to, or was greater than 9 lb 15 oz (4500 g). Rarely do babies weigh over 10 pounds (4.6kg). Although most LGA babies are born at term (37-41 weeks of pregnancy), a few premature babies may be LGA. How do they tell if baby is Large for Gestational Age (LGA)![]() Based on that, you may be told, or see, on your antenatal records, that you are a little large for dates or (LGA) -- but this measurement can vary depending on your size and shape. Women expecting second or subsequent babies sometimes do tend to measure slightly large for dates in their first and second trimesters. This may be due to the fact that their muscles have been weakened by a previous pregnancy, although I haven't actually seen studies to support this idea. Try not to be concerned if the fundal height is greater than dates, it may indicate twins, a large baby, mis-measuring, or even be because of fetal position. The most likely explanation is that everything is quite normal and that there is no need to worry. Doctors are more concerned when the fundal height is too small rather than too large, as this could indicate that the baby is not growing properly. If there is an unexplained discrepancy between size and dates, your care provider could arrange an ultrasound to determine the cause of any discrepancy. An ultrasound can provide a more accurate idea of how big your baby really is, but this is not always accurate. There can be a difference of 10-15 per cent between the weight predicted by ultrasound and the actual weight of the baby at birth, especially if you are close to your due date. During the ultrasound, several measurements are taken of the fetal body parts, fetus' head and limbs and these are compared with a growth chart to estimate fetal weight. This will only be, an estimation. The two main reasons why a baby might be LGA:
Excessive maternal weight gain
The group at greatest risk were those who gained more than 40 pounds and had gestational diabetes. Nearly 30 percent of these women had heavy babies, compared with 13.5 percent of women with gestational diabetes who had normal weight gains during pregnancy. Research findings suggest all women should avoid excessive weight gain during pregnancy. And women who are being treated for gestational diabetes should also strive to keep weight gain below 40 pounds. Weight gain during pregnancy has been rising over the past two decades, and some researchers suspect this may be fueling an epidemic of childhood obesity. Gain weight gradually in pregnancy In general, you should aim to put on between 25 and 35 pounds if you began your pregnancy at a desirable weight. If you're underweight to begin with, you can gain a bit more (28-40 pounds); if you're overweight at the start, your goal should be to put on a little less (15-25 pounds). If you're short (under 5 feet 2 inches), an adolescent, or are carrying more than one child, check with your doctor about how much weight you should gain. When you put on weight may be as important as the total tally of pounds. You should gain the least weight during the first trimester (roughly 2 to 5 pounds total) and steadily increase, with the greatest number of pounds (roughly a pound a week) coming in the third trimester, when the baby is growing the most. Women who eat well and gain the appropriate amount of weight are more likely to have healthy babies. So if you're eating fresh, wholesome foods and adding pounds, relax: You're supposed to be getting bigger.
