Diabetes, Family Planning and Pregnancy
Planning a pregnancy when you have diabetes
If you have diabetes and are planning a pregnancy, it is important that you talk to your Diabetes Nurse or Hospital Doctor beforehand. Blood glucose control is very important at the time of conception, which will be before you know you are pregnant. Good glucose control will help reduce the risks of health problems to yourself and the baby. To achieve this, you may need some help to adjust your diet or diabetes treatment or in performing extra blood tests. Also, there may be a need to change other medications to ones that are safe in pregnancy.
Before becoming pregnant, there are a number of things for you to consider:
You will be asked to test your blood glucose at least 4 times daily (before each meal and before bedtime) but extra tests may be necessary. For good control the blood glucose should be kept between 4-6 mmols before meals.
For patients taking Insulin
To achieve this good control, you may need extra insulin injections and your overall insulin dose will increase. Often you will end up taking around 3-5 times your usual daily dose - this is normal. As soon as the baby is born, your dose will return to your pre-pregnancy level.
In early pregnancy it is not uncommon to experience hypos more frequently. You may also find that the warning symptoms of hypoglycaemia are different from usual. It is important to be careful about driving, sleeping through snacks or spending long periods of time alone. If you are having frequent hypos, then it may be wise to stop driving altogether until you are around 16 weeks (or more) pregnant; your Diabetes team can advise you if you are worried about this.
Hypos may be more severe in pregnancy and you may need help from a friend or relative to treat them if you are unable to swallow sugary drinks. Friends or family can be taught to treat hypos using Glucagon injections, which can be prescribed by your GP.
See Hypo Leaflet
You will be asked to attend the hospital frequently for assessment by both the Diabetes and the Obstetric teams. Initially you will be seen every 2-4 weeks but later in pregnancy you will be seen every week. At around 20-22 weeks you will have a detailed ultrasound scan to check your baby's size and development. From around 26 weeks, the baby will begin to put on weight; it is important to keep your blood glucose control as near normal as possible at this time to avoid the baby growing too large. From about 28 weeks you will have a scan every 2 weeks to check on your baby's growth.
When you reach 36 weeks, ask your Diabetes nurse and midwife about how your labour will be managed and start to write your labour and delivery plan with your birth partner. You could teach your birth partner how to do blood testing. They also should know how to recognise your "hypo" symptoms.
Labour and Delivery
The aim is to try for a normal labour and delivery where possible. If your baby has become overweight or your blood pressure goes up, the obstetrician may wish to induce labour early. Ask your obstetrician or midwife about how this will be done in your case.
During labour your insulin and calories will be given in a "drip" containing glucose and insulin. The amount of insulin will be adjusted every hour depending on your blood tests. The drip will continue until after the baby is born.
You will go back to taking the dose of insulin you were on before your pregnancy as soon as your baby is born. Babies born to mothers who are treated with insulin always go to the Special Care Baby Unit (SCBU) for a short time for observation. You will be given the opportunity to visit the SCBU during your pregnancy and ask the staff there any questions you might have.
Women with diabetes can breastfeed! You must remember to eat a sufficient amount of starchy foods at each meal. This is because breast milk is high in carbohydrate. If you are taking insulin, you may also require less insulin while breastfeeding as the baby is taking carbohydrate away from you. Test before and after a few feeds so that you know how much to adjust your insulin and food intake by.
You no longer need to be as strict about your glucose control as you were during pregnancy. Remember you will be dealing with a new baby and sleepless nights! Your Diabetes nurse will keep in contact with you and will arrange a date for you to be assessed by the Diabetes and Obstetric staff.
