Gestational diabetes did cause a baby become fat, also called as ‘macrosomia’. It means "large body" and refers to a baby that is considerably larger than normal. It also one of the major problems a woman with gestational diabetes faces.
The baby receives all nutrients directly from the mother's blood, including extra glucose. It’s because, gestational diabetes’ mother usually does not produce enough insulin and the extra glucose goes to the baby through the blood. When the baby’s pancreas senses the extra glucose, it produces more insulin in an attempt to use the glucose. The extra glucose however gets stored as fat, make the baby gain weight and become larger than normal.
Occasionally, if the baby too large to be delivered through the vagina, a Cesarean delivery becomes necessary. Thus, the growth of the baby should be monitor and be determined by doing physical examination upon the mother’s belly. However, in many cases (such as my case), ultrasound is used to measure the size of the baby.
Baby become fat caused by gestational diabetes is manageable and preventable. The prevention is you must control your blood sugar levels very carefully as soon as the diagnosis of gestational diabetes is made. By maintaining normal blood sugar levels, it is less likely that your baby develops macrosomia.
