High-Risk Pregnancy FAQ
High-Risk Pregnancy FAQ
The midwife says I’m “high risk” because of my blood pressure. What does this mean?
Blood pressure is monitored in pregnancy as raised blood pressure can be a sign of pre-eclampsia (see p39) At your first antenatal visit, your midwife will record your blood pressure and assess your risk of pre-eclampsia based on the blood pressure reading, your medical history and family medical history Certain factors increase your risk These include: * High blood pressure.
* Pre-eclampsia or raised blood pressure in previous pregnancies, or having a mother or sister who had pre-eclampsia.
* Being aged over 40 years and this being your first pregnancy.
• Being significantly over- or underweight
• Having a multiple pregnancy.
If your midwife thinks you are ”high risk”, she will refer you to a consultant obstetrician and discuss a plan of care for your pregnancy Many women who are assessed as high risk have pregnancies that progress without complications, but they are monitored a little more closely
I’ve been told that because of my diabetes I have to go to the hospital clinic - why is this?
Whether you develop diabetes in pregnancy (known as gestational diabetes), or have pre-existing diabetes, you will require special care with support from a diabetic health care team and a consultant obstetrician. This is because diabetes poses risks in pregnancy if there is poor control of blood glucose levels In the mother, these include hypertension (high blood pressure), thrombosis (blood clots), pre-eclampsia, diabetic kidney disease, and diabetic retinopathy a condition that affects the retina in the
eye. For the baby, there is an increased risk of congenital abnormalities and growth may be too fast or too slow. It is important that your care is tailored to you, taking into account any other complications you may already have from diabetes.
The key to a healthy pregnancy and baby when you have diabetes is good blood glucose control as your insulin requirements will change throughout pregnancy Controlling blood glucose levels reduces the risk of birth defects and stillbirth, or a larger than expected baby, which can present problems during birth. If you have gestational diabetes, you will need to adapt your diet to include carbohydrates and fibre and reduce fats and sugar: you may also need insulin injections to help control blood sugar levels
I have epilepsy - will I need special care in pregnancy?
Ideally, women with epilepsy should discuss their situation with their doctor prior to conception. Epilepsy and the medication used to control it do carry some risks in pregnancy but there are ways to minimize these. Some anti-epileptic drugs (AEDs) are thought to be more harmful to a developing baby than others, so your doctor may wish to change your medication before you become pregnant. Although
most women taking AEDs have healthy babies, taking any type of AED increases the risk of birth defects, so you will probably be offered extra scans. The aim is to control your seizures on the minimum dose AEDs also restrict your body’s absorption of folic acid, which reduces the risk of an unborn baby developing neural tube defects such as spina bifida, so your doctor will probably discuss taking a higher dose of folic acid. Once your baby is born, you will generally be advised to breastfeed if at all possible, as any risk to the baby from AEDs is outweighed by the many health benefits of breast milk
I’m 28 weeks and have been having contractions. Is my baby going to come early?
From early pregnancy, the uterus ‘practises` contracting in preparation for labour. A mother is usually unaware of these practice contractions, known as ”Braxton Hicks”, until later in pregnancy, when they can be felt as a hardening of the ”bump’ Each contraction lasts from a few seconds to a few minutes before the uterus relaxes and becomes soft
again. These contractions are painless (although
they can feel quite uncomfortable!), follow no regular pattern, and having them does not necessarily mean that your baby is going to be born early
However, if you experience painful contractions -described as being like strong ”period-type” pains -and they seem to increase in strength and frequency, you should contact your hospital as you could be
going into labour. You should also seek medical advice if you leak any fluid or blood from the vagina
My last baby was premature -is this likely to happen again?
Having one premature baby, born before 37 weeks of pregnancy, means that you have about a 15 per cent chance of having a second preterm birth, although this also depends on why you had a premature birth originally, Reasons why babies are born prematurely include
Infection in the mother
Early rupture of the membranes (’waters breaking”)
• Multiple pregnancy.
• Weak, shortened cervix (neck of the womb).
• Unusual shaped womb, for example, a bicornuate uterus (heart-shaped womb).
* A medical condition in the baby, for example if the baby is not growing as expected, which means that labour has to be induced early.
* A medical condition in the mother, such as pre-eclampsia (see opposite). which also means that labour has to be induced early.
Although most of the causes of premature
birth cannot be prevented, there are steps you can take to reduce the risk of premature labour. These include not smoking, avoiding being under- or overweight. and avoiding extreme stress In addition, it is essential that you attend all your antenatal appointments so that the wellbeing of both you and your baby is constantly assessed You should discuss whether there was an obvious reason for your last baby being premature. and if there are any specific preventative measures you can take to help avoid a reoccurrence this time round.
I’m expecting triplets. Will I be treated as “high risk”?
Yes, you will be classed as having a high-risk pregnancy as all the usual risks are increased for women with twins and multiple pregnancies This is partly because hormone levels are higher when there is more than one baby and partly because it is hard work for your body to carry and nourish three little lives! There will be an increased risk of miscarriage; severe pregnancy sickness (hyperemesis gravidarum); raised blood pressure/ pre-eclampsia: anaemia (iron deficiency), diabetes: and premature and/or low birth weight babies There is also an increased, although small, risk that one or more of the babies will die during the pregnancy With triplets, you will almost certainly need to give birth by Caesarean section Although considered a very safe operation, this is still major surgery and carries the associated risks.
You can expect to be referred to an obstetrician, who will plan your antenatal care with you and you will probably have more frequent checkups and scans. If you attend all your appointments and look after your health, it is likely that you will have three healthy babies at the end of your pregnancy. For more information about multiple pregnancy and details of local support groups, contact the Twins and Multiple Births Association (TAMBA) (see p.310).
I have lupus - how will this alter my care during pregnancy?
Lupus is an autoimmune disease that causes inflammation in the bone joints, blood, kidneys,
and skin and sufferers often find that symptoms flare up due to certain triggers. The condition is more common in women than men, especially women of childbearing age Some women find that pregnancy aggravates lupus, causing a flare-up, probably due to the hormonal changes that occur, while others find that pregnancy eases the symptoms. As lupus can affect an unborn baby, increasing the risk of stillbirth, miscarriage, premature labour, and slow growth, your pregnancy will be monitored very closely, especially when checking your blood pressure and
urine However the likelihood is that you will have a completely healthy pregnancy resulting in a healthy baby You can contact Lupus UK for support and information (see p.310)
I’ve had a few small bleeds during pregnancy - will my baby be OK?
Bleeding in early pregnancy is not uncommon Usually, the reason is unknown, but there is a theory that although the hormones of the menstrual cycle are suppressed, variations in the cycle continue. This could explain why some women have light “spotting” around the time a period would be due. If the bleeding is light, and not accompanied by abdominal cramping or pain, then it is unlikely that there is anything wrong
Bleeding after early pregnancy can be due to
a cervical ectropian, when the surface of the cervix becomes ‘raw’. This results from hormonal changes and is not harmful to the baby. Sexual intercourse can aggravate a cervical ectropian, stimulating bleeding.
Bleeding in late pregnancy may be more serious as it can be due to the placenta partially, or totally,
detaching from the wall of the uterus, known as placental abruption, or to a low-lying placenta, known as placenta praevia (see below and p.92).
If you have a mucus discharge tinged with blood in late pregnancy, this may be a ‘’show” when the plug of mucus sealing the cervix comes away. This is normal and can indicate that labour isn’t far away
It is important that you seek advice for any type of bleeding at any stage of pregnancy, as serious causes for bleeding must always be ruled out
We know our baby has Down’s syndrome. How can we best prepare ourselves?
On a practical level, you can prepare in much the same way as every parent, thinking about your preferences for labour, attending antenatal classes, and buying baby equipment Knowing in advance that your baby is going to be born with a condition such as Down’s gives you time to adjust and find out as much as possible about what to expect. You may wish to tell family and friends too, to give them time to prepare. Ask your health visitor for details of local support groups and contact the Down’s Syndrome Association for more information (see p.310).
I had an emergency Caesarean last time. Now the doctor says I’ll have a trial of labour, what is this?
This means labour after a Caesarean section. Another term is VBAC (Vaginal Birth After Caesarean section). Until relatively recently, most doctors
advised women who had had a Caesarean to have a planned Caesarean for the next baby to avoid uterine rupture, where the Caesarean scar tears in pregnancy or labour. Although serious this is rare, and it is now thought to be preferable for both the mother and baby to have a natural vaginal delivery if possible. Even so, if you want a vaginal delivery, it would be wise to opt for a unit that has fetal heart monitoring and that can carry out Caesareans if one turns out to be required.
Your chances of having a successful labour depend partly on why you had a Caesarean section. If it was because the baby was breech or you had a low-lying placenta, -your chances of a natural labour this time are higher If it was due to complications in labour, such as slow cervical dilatation, then the problem may recur Overall, about half of women have natural deliveries after a Caesarean You can contact the Caesarean organization for more information (see p.310).
My friend had placental abruption. Is this serious?
Placental abruption means that the placenta has started to come away from the wall of the uterus before the pregnancy has reached full term. This is a potentially serious condition that may mean the baby needs to be delivered as soon as possible by Caesarean section. If there is persistent pain in the abdomen during pregnancy which may be accompanied by fresh, bright red bleeding and/or a change in the baby’s movements, then medical help should be sought straight away
I have had three miscarriages -will my antenatal care be different because of this?
While one or even two miscarriages are relatively common, three is less so. If you have had recurrent miscarriages, you will be offered extra antenatal care. You may be advised to take low-dose aspirin if there is evidence that you have a blood-clotting condition called anti-phospholipid syndrome (aPL). A vaginal scan may also be offered to check if you have a ”weak cervix”, where the cervix is unable to support the growing baby. If a weak cervix is diagnosed, you may be given a stitch during pregnancy to hold the cervix shut. There is some evidence that taking the hormones progesterone or human chor 4 onic gonadotrophin in early pregnancy can reduce the risk of miscarriage.
My baby is very small for her dates - can anything be done about this?
From 25 weeks, your midwife will measure and palpate your tummy to estimate the fetal size If she thinks you are ‘’small for dates” she may refer you for a scan for a more accurate assessment of the baby’s size and of the efficiency of the placenta You may be offered a repeat scan in a week or so to measure growth over time. If babies do not grow as they should, this is called intra-uterine growth restriction (IUGR). This can be due to a problem with the baby or the placenta, affecting the amount of oxygen and nutrients reaching the baby, Pre-eclampsia can cause IUGR, as can smoking, drinking alcohol, and
recreational drugs. If your baby is very small and the rate of growth drops off considerably, it may be necessary to deliver the baby early
My friend had hyperemisis gravidarum in her pregnancy -can you tell me more about this?
Hyperemesis gravidarum (HG) is severe pregnancy sickness, a debilitating condition affecting around one per cent of women. The woman is unable to keep down food or fluids without vomiting and becomes clinically dehydrated. This can begin at around week 6 of pregnancy and may last until 16-20 weeks (although some women suffer
throughout pregnancy). Sufferers may need hospital treatment with intravenous fluids, and medications to control the vomiting may be given, but their success varies No-one is sure what causes the condition,
but it is thought that high levels of the hormone hCG, fluctuations in thyroid levels, and changes in liver function may all be involved Sometimes the condition runs in families. There is a support group that provides information and tips (see p.310).
Placenta praevia
Placenta praevia means a low-lying placenta, which occurs when the placenta is either partially covering (minor), or completely covering (major), the cervix. In major placenta praevia, the baby cannot be born vaginally Major placenta praevia poses a high risk of heavy bleeding, either in the later stages of pregnancy or during the actual labour, which is treated as an emergency If a low-lying placenta is detected at your 20-week scan, you may be offered
a scan in late pregnancy; this is because the placenta may ”move up” as the uterus grows, and by about 34 weeks may no longer be low. If you have placenta praevia, particularly major placenta praevia, most hospitals admit you for bedrest in the last weeks of pregnancy until the birth so that if you bleed heavily, you can be treated immediately
Cholestasis is a condition in which bile does not flow freely down the bile ducts in the liver, causing bile to leak into the bloodstream. This condition poses serious risks for both the mother and the baby, and so it is important that it is diagnosed with a blood test and managed as soon as possible. Medication will be given to relieve the itching and improve the liver function. The aim of the medication is to stabilize the condition until it is safe for the baby to be delivered. Usually labour is induced between 35 and 38 weeks of pregnancy.
Pre-eclampsia is a condition that affects around 10 per cent of women during their pregnancy (or, rarely, in the first 72 hours after the delivery) The cause is still unknown. although it is thought that it may be caused by a malfunction of the placenta.
What are the symptoms? There are varying degrees of pre-eclampsia, from your blood pressure rising a little bit towards the end of your pregnancy and a small amount of protein detected in your urine (which affects about 1 in 10 pregnant women), to a large rise in your blood pressure and a considerable amount of protein found in your urine (affecting about 1 in 50 pregnant women) Your blood pressure and urine will be checked (and the size of your baby measured) at your antenatal appointments to look for signs of pre-eclampsia and you will be referred to the hospital if necessary. Sudden swelling, headaches, pain =der your ribs, and visual disturbances also indicate pre-eclampsia and you should contact your midwife or doctor straight away if you experience any of these.
What can be done? If you have the milder form of pre-eclampsia, this will only require your blood pressure and urine being tested a little more frequently – perhaps weekly However, the more serious form will require you to go into hospital where you and your baby will be monitored and given medication to lower your blood pressure This is because if you are left untreated it could develop into eclampsia, which is a very serious condition in which you may suffer convulsions, and your and your baby’s lives could be in danger. However, with both types of pre-eclampsia, you will generally need
to be induced early (see p 190) as once your baby is born and the pregnancy is over, this will end the pre-eclampsia.
Who is at risk? Women are at a greater risk of pre-eclampsia if they have had the condition before; are over 40 years old have a body mass index (BMI) over 35; have a family history of pre-eclampsia (mother or sister); had high blood pressure, diabetes, or kidney disease before the pregnancy; or are carrying more than one baby.
Prescribed bedrest
Towards the end of pregnancy, there are some circumstances when you may need to be admitted into hospital for bedrest and monitoring.
* If you have contractions, but your waters haven’t broken; you may also be given a drug to slow contractions.
* If you develop pre-eclampsia in
pregnancy you may have to stay in hospital and measures will be taken to reduce your blood pressure.
* If you have placental abruption (see p 91), you will be monitored in hospital and early delivery may be needed
