What's are the risks with pre-eclampsia

asks Redhillmum:
A. Pre-eclampsia is a condition that develops during the second half of pregnancy and is caused by a defect in the placenta. This results in a restriction in the baby's blood supply, reducing the supply of nutrients and oxygen.

�

Q. Does it affect the mother
A. Yes, it affects her circulation, causing high blood pressure, protein in the urine and swollen hands, feet and face. Occasionally it can lead to more serious complications, such as eclampsia - or convulsions,� and liver, kidney and lung problems.

�

Q. How do you know you've got it
A. It's hard to detect in the early stages. That's the reason why all pregnant women are screened at each antenatal appointment - their blood pressure is checked and a urine sample is taken to check for protein. Pregnant women should see a doctor immediately if they develop any of the following: swelling of hands, feet and face, headaches, blurred vision or flashing lights in the eyes, a pain below the ribs or sudden vomiting.

�

Q. What happens when it's detected
A. It usually means hospital admission for close monitoring.

�

Q. What's the treatment
A. If the condition deteriorates, the only treatment is to deliver the baby, which usually means a Caesarean birth or induction to bring forward the birth. Most mothers and babies make a full recovery.

�

Q. What are the statistics
A. Pre-eclampsia affects one in ten pregnancies - severely in one in 50 cases. Between seven and ten women die from it in the UK each year.

�

Q. How can you tell if you're at risk
A. First-time mothers are more at risk (including a first baby with a new partner). There's also a higher risk if the mother is under 20 or over 35, if she has high blood pressure or a kidney disease, if she suffers from migraines, if it is a multiple birth. A woman who has had pre-eclampsia has a 1 in 20 chance of getting it again, and will get more frequent check-ups with a subsequent pregnancy.

�

Q. How can it be prevented
A. Research at St Thomas' Hospital, London, found that taking high doses of the vitamins C and E in early pregnancy can reduce the risk. However, pregnant women should always�consult a doctor before taking high doses of vitamins.
