If you have type 1 or 2 diabetes visit your GP or your antenatal diabetes team as soon as you suspect you may be pregnant.
All women planning to become pregnant are recommended to take folic acid to help prevent birth defects, such as spina bifida. If you have diabetes you are at higher risk of having babies with these disorders, so you should take a higher dose of folic acid (5mg per day). This higher dose can only be prescribed by your doctor because it isn't available over the counter.
Once pregnant you should continue taking folic acid until you are 12 weeks into your pregnancy.
You can expect to be referred to the joint diabetes and antenatal clinic immediately, or by ten weeks at latest. Your first scan should take place at 7-9 weeks.
If you had not been seeing the preconception team, the team should give you the full range of information and advice and take a clinical history to check your risk of diabetes-related complications. You will also have your HbA1c tested. This may be checked later in your pregnancy too, to assess your level of risk.
The team will check your medication to see if you need to switch to a different type now you are pregnant.
If you have not had your eyes and kidneys checked in the past year, you will need to be assessed at this stage. This is because you are at higher risk of eye and kidney problems during pregnancy.
'I’d been told that it would be a bad idea to get pregnant because I’d had early-stage retinopathy, but then I fell pregnant by accident. I had some laser treatment, but it came back towards the end of my second pregnancy.' Sara, mum of two
From this point onwards, you will have appointments every 1-2 weeks. You will have regular ultrasound scans to check how your baby is growing, and will also have regular Hb1Ac tests, blood pressure and urine samples.
Throughout your pregnancy you are at increased risk of hypos if you are treated with insulin, but you may be less sensitive to hypos than usual (hypo unawareness), so you need to make sure you are always prepared with handy hypo treatments such as glucose-containing drinks. You may be prescribed dextrose tablets to help you manage any hypos.
If you have type 1 diabetes you may also be given a glucagon kit which can be used by someone else if you’re unconscious during a hypo.
'My diabetes nurse gave me a little paper diary so I could write down my blood glucose test results, so I'd go along with that every two weeks and she'd look at it, and between us we'd decide what adjustments to make to my insulin.' Prisha, mum of two
Morning sickness and diabetes
If you get morning sickness and actually throw up, be aware that this can affect your blood glucose levels, so you will need advice about how to time your insulin injections. So if you are getting sick, talk to your team. For many women, morning sickness passes after the first few weeks of pregnancy.
Many women with type 1 or 2 diabetes go on to have a healthy birth. But you are at higher risk of complications so your healthcare team will have recommendations for the birth of your baby.
You may be able to use diet and exercise alone to keep your blood glucose levels within safe limits during pregnancy.
You may need support with your emotional well-being as you go through a pregnancy with type 1 or 2 diabetes
Whatever treatment you were using to control your diabetes before you became pregnant may change. If you were using tablets, you may have to start using insulin.
If you have type 1 or 2 diabetes, managing your blood glucose levels can now be much harder in pregnancy. Testing is an important part of self-care.
If you are treated with insulin in pregnancy, by the third trimester your insulin requirements are likely to be much higher than they were before.
By the second trimester, as your baby grows and starts to kick, you may need more insulin. Your medication and insulin needs will be regularly reviewed with you.
