Final answer:
Serial growth scans are typically indicated for women diagnosed with Gestational Diabetes Mellitus (GDM) to monitor fetal growth, particularly after a glucose tolerance test confirms hyperglycemia indicative of GDM. These scans help detect any potential complications, like macrosomia, ensuring the health of both mother and fetus.
Step-by-step explanation:
When asking about when serial growths are indicated for GDM (Gestational Diabetes Mellitus), it is vital to understand that monitoring and management are crucial. In the context of pregnant women diagnosed with GDM, serial growth scans, also known as serial ultrasounds, are used to monitor the growth and health of the fetus. These scans are typically recommended because GDM can lead to conditions like macrosomia, where the baby grows too large, which can complicate delivery and might lead to a cesarean section.
Glucose tolerance tests are used to confirm the diagnosis of GDM. This test involves measuring the body's ability to metabolize glucose at various intervals after ingesting a glucose-rich drink. If hyperglycemia, which is an abnormally high blood glucose level, is observed during this test, it can confirm the presence of GDM.
Therefore, serial growth ultrasounds may be indicated in the management plan for GDM, especially if the glucose tolerance test shows significant hyperglycemia, to ensure the well-being of both the mother and the fetus by closely tracking fetal development and growth.
