what's the number of times the letter "u" appears in:
it can have no symptoms if it develops gradually rather than coming on suddenly.
a blood pressure reading above 140/90 millimeters of mercury (mm hg) on two occasions is usually the first sign.
sudden weight gain, and swelling in the face and hands, are also symptoms, however, these can occur during normal pregnancies.
pre-eclampsia is thought to begin in the placenta when its blood vessels narrow and do not react to hormones properly.
this reduces the amount of blood that flows through them.
its underlying cause may be genetic, due to a problem with a woman’s immune system or existing blood vessel damage.
a woman is more at risk if she, or a member of her family, suffered from pre-eclampsia before.
the risk is also highest during the first pregnancy, and if a woman is over 40; obese; black; having a multiple birth, like twins; or conceived via ivf.
existing medical conditions like high blood pressure, diabetes, migraines and kidney disease also raise the risk.
if untreated, pre-eclampsia can restrict a baby’s growth or cause it to be delivered early.
the placenta can also separate from the uterus wall, which can lead to severe bleeding.
a woman may also suffer seizures, organ damage and even heart disease as a result of untreated pre-eclampsia.
although treatment is usually inducing labour, if it is too early to deliver the baby, medications may be prescribed to lower a woman’s blood pressure.
there is no clear advice on how to prevent pre-eclampsia, however, research suggests taking a low-dose of aspirin and calcium supplements may help.
pregnant women should talk to their doctor before taking any drugs or supplements.
