In many cases, thecause of a miscarriage isn't known and you wouldn't have been able to prevent it.
However, there are ways to lower your risk of miscarriage, including:
Obesity increases your risk of miscarriage. A person is obese when they havea body mass index (BMI) of over 30. You can check your BMI using the healthy weight calculator . If you're pregnant, your midwife or doctor may be able to tell you your BMI.
The best way to protect your health and your baby's wellbeing is to lose weight before you become pregnant. By reaching a healthy weight, you cut your risk of all the problems associated with obesity in pregnancy. Contact your GP for advice about how to lose weight. They may be able to refer you to a specialist weight-loss clinic.
As yet, there's no evidence to suggest losing weight during pregnancy lowers your risk of miscarriage, but eating healthily and activities such as walking and swimming are good for all pregnant women.
If you weren't active before becoming pregnant, you should consult your midwife or doctor before starting a new exercise regimen while you're pregnant.
