If you are overweight, you may suffer from fertility problems. This means that it can make it pregnant quite difficult. Both weight and fat distribution affect fertility.
When your BMI is too high, your cycle may be disrupted. Overweight women often have fewer ovulations, which occur in less menstruation or irregular menstrual periods. Even in a regular cycle, overweight women are less fertile compared to women with healthy weight. Also, the chance of succeeding in fertility treatment decreases when you are overweight.
Once pregnant, being overweight gives a higher chance of complications during pregnancy and childbirth. This includes preeclampsia or diabetes. The risk of miscarriage is also greater. Similarly, when receiving an epidural during childbirth. Operating tables and beds are not designed for excessive weight.
Not only for the mother are there risks, but also for the (unborn) child. Children of mothers who are overweight during pregnancy are born prematurely at a higher rate. They also have more chances of diseases, including of the heart. Often it is also that heavier women get heavier children. The risk of obesity is therefore also greater in your child. Your own weight can therefore also affect your baby's health. In short: there are a number of increased risks in being overweight.
It is recommended that you get your own health sorted before you get pregnant. Losing weight slowly. Do not try crash diets to lose weight if you want to become pregnant, but go to your GP or dietician. They can help you to lose weight healthily without risking your own health.
