Diabetes before pregnancy: Why Planning Care Matters

If you have type 1 or type 2 diabetes, ask for specialist preconception care before trying for a baby. Managing glucose and reviewing treatment before pregnancy can reduce important risks, although it cannot remove them completely. This advice concerns diabetes already present before pregnancy, which is different from diabetes first diagnosed during pregnancy.

Agree glucose goals with the team

The care team will review your glucose records and HbA1c, which reflects glucose levels over time. UK guidance generally aims for HbA1c below 48 mmol/mol, or 6.5%, before conception when this can be achieved without problematic low glucose. Your daily monitoring goals and treatment plan need individual agreement.

Do not make abrupt insulin changes or pursue low readings at any cost. Ask what a safe improvement plan looks like, when to repeat HbA1c, and how to handle hypoglycaemia. Discuss contraception while treatment and glucose control are being optimized.

Review more than diabetes medicines

Bring every prescription and supplement, including treatment for blood pressure or cholesterol. Some medicines need changing before pregnancy, but that should happen with the prescriber. Do not stop insulin or another essential treatment because you are worried about a possible pregnancy.

The medicine review guide explains how to prepare the list. Ask who to contact if you become pregnant before the planned review is complete.

Arrange folic acid and health checks

In the UK, people with diabetes planning pregnancy are advised to take prescribed folic acid at 5 mg daily through the first twelve weeks of pregnancy. Ask for the prescription rather than trying to build that dose from multiple pregnancy multivitamins. Your clinician can confirm the recommendation for your location and circumstances.

Eye and kidney assessments are part of preconception care. If you have eye disease, the team may need to coordinate its treatment before rapid glucose improvement. These checks complement glucose management rather than replacing it.

Plan for illness and a positive test

Ask for written instructions about high or low glucose, vomiting, and when to seek urgent help. People with type 1 diabetes need advice and equipment for blood ketone testing when glucose is high or they are unwell. Follow your own sick day plan and contact the team promptly if you cannot manage safely.

Contact your diabetes team as soon as you know you are pregnant. The specialist planning guide can help clarify who coordinates your diabetes and maternity appointments. You deserve practical support rather than blame for a result outside your target.
