This prospective pilot study is exploratory in nature and is designed to evaluate the validity of continuous glucose monitor (CGM) use for perioperative glucose surveillance during scheduled Cesarean delivery for nondiabetic patients. Primary objective is characterization of perioperative glucose trends during elective Cesarean delivery in patients without diabetes and exploratory analyses will describe perioperative glucose patterns captured by CGM. Secondary objective is to examine rates of and associations with post-operative complications, including surgical site infections.

Inclusion Criteria:

• singleton pregnancy
• no prior diagnosis of diabetes (gestational included)
• scheduled term cesarean delivery in Mount Sinai Health System
• aged 18-50 years

Exclusion Criteria:

• preexisting diabetes mellitus
• diagnosis of gestational diabetes mellitus (GDM) in the current pregnancy, based on standard prenatal screening
• known endocrine disorder affecting glucose metabolism (such as Cushing syndrome, poorly controlled thyroid disorder, etc.)
• use of antenatal steroids within the two weeks prior to delivery
