Getting pregnant when you are an ideal healthy weight is much better for you and your baby. If you are overweight and thinking of pregnancy it’s good to address your weight before you start trying to conceive.
The weight may have crept on over the years or you may still be carrying ‘baby weight’ from previous children. Whatever the reason, you’ll have more physical energy and be less at risk of medical problems in pregnancy if you are a healthy weight at the start.
Harder to Get Pregnant
There’s evidence that being overweight will hamper your efforts to fall pregnant. Being overweight can affect your hormones and ovulation patterns, too.
If you’re in a healthy weight range, with a BMI between 20 and 25, you may have a better chance of becoming pregnant, according to the NHS.
If your BMI is 25 or over, you are overweight. With a BMI of 30 or more, defined as being obese, your chance of a successful conception decreases.
A 2008 study in the Netherlands found that in women who were less fertile than normal, for every BMI value over 29, the chance of pregnancy fell by 4%. That’s around the same reduction in fertility as an additional year of age.
Research also shows that the average wait for pregnancy for healthy weight women was 3 months, but being overweight delayed it for up to 8 months.
