Final answer:
Fetal hyperglycemia is a condition characterized by high blood glucose levels in a developing fetus. It can be caused by maternal diabetes, defective pancreas, or glycogen storage diseases. Glucose tolerance tests and hormonal stimuli can help detect fetal hyperglycemia.
Step-by-step explanation:
Fetal hyperglycemia refers to a condition where there is abnormally high blood glucose levels in a developing fetus. It can occur due to various factors such as maternal diabetes, defective pancreas, or glycogen storage diseases. For example, during pregnancy, the demand for glucose is doubled, leading to overproduction of ketone bodies and hyperglycemia. Fetal hyperglycemia can be detected through glucose tolerance tests or by observing the effects of certain hormonal stimuli.
