If you are thinking about having a baby, there are some things you need to do before you start trying for a baby. Contraception and general pregnancy advice Ask your GP, endocrinologist or obstetrician for help to choose the best contraception for you and your partner while you are planning and preparing for pregnancy. Referrals Ask your GP for referrals to see diabetes health professionals such as an endocrinologist, credentialled diabetes educator/diabetes nurse practitioner and accredited practising dietitian, and discuss your options for specialised maternity care. Blood glucose targets Aim for an HbA1c of 6.5% (48mmol/mol) or less before pregnancy (or as close to this target as possible depending on hypoglycaemia risk). Discuss individual blood glucose targets with your health professionals. Folic acid Start taking high-dose (2.5–5mg/day) folic acid ideally months before becoming pregnant and continue during the first three months of pregnancy. Medication review Ask your doctor to review all the medications you are taking (including diabetes tablets, blood pressure and lipid medication) to check if they are safe to take during pregnancy. Continuous or flash glucose monitoring Ask your diabetes health professionals for information about continuous glucose monitoring (CGM) or flash glucose monitoring (Flash GM) technology and access through the NDSS. Review insulin therapy Talk to your health professionals about whether the type of insulin you are taking and your insulin doses need any changes. Consider whether an insulin pump might be a good option for you. Diabetes-related complications and screening Have a full complications screening and any complications treated and stabilised before becoming pregnant. A thyroid function and coeliac disease screening should also be done. Your doctor may also do additional tests such as checking your vitamin D level. Blood pressure Have your blood pressure checked and stabilised before becoming pregnant. Weight management Aim for your weight to be as close as possible to the healthy range before pregnancy. Discuss pregnancy weight gain with your health professionals. Diet and supplements Take a supplement that contains at least 150 micrograms (150ug or mcg) of iodine and check with your doctor and/or dietitian whether you need to take a multivitamin or other supplements. Women with an overactive thyroid or Graves disease need to see their doctor for advice before taking an iodine supplement. Vaccinations Make sure your rubella and chickenpox vaccinations are up to date. If needed, immunisations should be done at least one month before conception. You will be advised to have influenza (flu) and whooping cough vaccinations during your pregnancy. Discuss immunisations for pregnancy with your doctor, including current recommendations regarding COVID-19 vaccination. Smoking and alcohol If you are a smoker, stop smoking. Ask your health professionals for help. Avoid alcohol and other drugs completely during pregnancy. Related resource Your health care team in pregnancy Planning for pregnancy
