An anatomical illustration of the human pancreas shows its location near the stomach and intestines, a detailed cross-section highlighting ducts and the islet of Langerhans, and an inset of pancreatic tissue histology with labeled alpha, beta, and delta cells. — diabetes mellitus The islets of Langerhans are responsible for the endocrine function of the pancreas. Each islet contains beta, alpha, delta, and pancreatic polypeptide (PP) cells that are responsible for the secretion of pancreatic hormones. Beta cells secrete insulin, a well-characterized hormone that plays an important role in regulating glucose metabolism.

Gestational diabetes mellitus is a temporary condition characterized by elevated blood glucose levels during pregnancy. It poses several health risks to both the pregnant person and the developing fetus.12

Risks to the Baby

Fetal Macrosomia: Babies may grow unusually large, which can lead to birth trauma and difficult deliveries.132
Metabolic and Respiratory Issues: Newborns may experience neonatal hypoglycemia (abnormally low blood sugar) and respiratory distress syndrome due to premature delivery.12
Mortality: There is a higher incidence of fetal-neonatal mortality and stillbirths associated with the condition.32

Risks to the Pregnant Person

Preeclampsia: Pregnant individuals face an increased risk of developing this serious blood pressure disorder.13
Labor Complications: Due to the increased size of the fetus, there is a higher likelihood of birth trauma and the potential need for a cesarean section.12
Long-term Health: Women who experience gestational diabetes have an increased risk of developing type II diabetes mellitus later in life.12

Adequate medical supervision and blood glucose control are essential to mitigate these risks and ensure a safe pregnancy.32
