Gestational diabetes is characterized by?

• A. High blood glucose in pregnancy.
• B. Low blood glucose in pregnancy.
• C. High blood glucose in childhood.
• D. Low blood glucose in childhood.

Answer: (A)

Gestational diabetes is a condition in which high blood glucose develops during pregnancy due to insulin resistance caused by pregnancy hormones. As pregnancy progresses, hormones like human placental lactogen make the body less responsive to insulin. If the pancreas can’t produce enough insulin to overcome that resistance, glucose stays elevated in the blood. This is why the hallmark is high blood glucose during pregnancy, not low glucose and not related to childhood. It’s typically diagnosed during pregnancy and often resolves after delivery, though it increases the risk of future type 2 diabetes.
