Insulin Pump During Pregnancy: Settings and Care Plans

What does the evidence say about insulin pump during pregnancy?

1. A pump delivers insulin through a device worn on the body; a glucose sensor measures glucose trends. Some systems connect these functions, while others do not. Understanding which parts of your system deliver insulin and which provide information is essential for troubleshooting. 1
2. ADA 2026 guidance supports either multiple daily injections or pump technology in type 1 pregnancy and distinguishes automated systems with pregnancy-specific targets from other algorithms. The exact device and experienced clinical support matter more than the generic label closed loop. 2
3. Sensor systems differ in calibration needs, alerts, and data sharing. Ask when a meter check is needed and what to do when symptoms and readings disagree. An alarm is information requiring the agreed response, not proof that the system has already corrected a problem. 3
4. Insulin requirements may shift during pregnancy and fall rapidly after birth. The pump plan needs regular review across these changes. A setting that worked before conception or near delivery should not automatically remain unchanged postpartum. 4
5. Some people continue their pump during labor, with glucose monitoring and adjustments coordinated with the hospital team. Discuss the hospital's approach and an alternative delivery method before admission in case circumstances change. 5

How should the pump plan change through pregnancy?

• First trimester. Before or early in pregnancy, review the specific device, targets, training, and backup supplies.
• Second trimester. As needs change, share glucose data and follow the agreed setting-review plan.
• Third trimester. Before delivery, confirm the labor and postpartum plans for the pump and alternative insulin delivery.
