What is pregnancy weight gain made up of?
There are several different things that contribute to the weight you put on when you are pregnant. These include:
- your baby
- the placenta
- the amniotic fluid (the water surrounding your baby)
- your growing breasts
- the increased blood you need
- extra fat stores
- natural fluid retention.
These changes in your body, such as extra fat and increased blood volume, are important for the health of your baby and the pregnancy. This is not the time for dieting. If you're worried about putting on weight, remember that you will lose a lot of it with the birth of your baby and the placenta. Breastfeeding can also help with weight loss.
If you eat a balanced amount of different foods and stay active, it’ll be easier to control your weight gain in pregnancy. It will also make it easier for you to lose any extra weight after you give birth.
Can I try to lose weight while I’m pregnant?
Don't try to lose weight while you're pregnant as this is not healthy for you or your baby. If you have a high BMI, the health professionals looking after you will be aware of this and will help you take steps to eat well and reduce the risks to you and your baby.
