Planning for Pregnancy


Click to return to Resources for People with Type 1 Diabetes Main Page

Women with Type 1 Diabetes can experience safe and successful pregnancies with proper care and preparation. 

Consult your healthcare team about your plans to conceive. Use reliable contraception until you are ready. 

Work with your healthcare team to achieve optimal blood glucose control before conception. Your doctor will also screen for any diabetes-related complications. 

Your team might recommend using a continuous glucose monitoring sensor or an insulin pump during pregnancy, possibly starting before conception.  

Expect significant changes in insulin needs and blood glucose levels throughout pregnancy. Regular follow-ups with your diabetes team and obstetrician are crucial. 

Targets during pregnancy are more stringent than those for non-pregnant individuals. 

An example of blood glucose targets during pregnancy: 

Before meals4.4 to 5.5 mmol/L
2h after a meal5.5 to 6.6 mmol/L

Achieving these targets requires regular blood glucose monitoring (up to seven times daily) or the use of a continuous glucose monitoring sensor. Familiarize yourself with flexible insulin dosing principles from our resource page to maintain tight glucose control during pregnancy. 

Insulin requirements may decrease substantially after delivery. Breastfeeding is encouraged, but insulin doses may need further reduction to prevent hypoglycaemia. Your healthcare team will work with you for insulin dose adjustments during this period. Discuss with your doctor the timing for your next pregnancy and appropriate contraception for family planning.
