There are a number of things that can increase your chances of developing Pre-Eclampsia, such as:
If it is your first pregnancy
If you developed the condition during a previous pregnancy
If you have a family history of the condition
If you have an existing medical problem - for example, diabetes, kidney disease or high blood pressure
If you are over 40 years old
If you are expecting multiple babies (twins or triplets)
If you are thought to be at a high risk of developing Pre-Eclampsia, you may be advised to take a daily dose of low-dose aspirin from the 12th week of pregnancy until your baby is delivered. Evidence suggests this can help lower your chances of developing the condition.
