Avoid obesity during pregnancy. Don't think that being pregnant is a big baby. Just for the children in the belly, three meals a day is not enough, and some snacks and supper are needed. This is very unfriendly to your weight and harmful to the child in your belly. You can properly supplement nutrition during pregnancy, but you must never eat or sleep. You always eat so much every day. It is also true that we are overweight. Many places or countries have requirements for the weight of pregnant women, so it is better to control the child within 5 kg as much as possible. For pregnant women, the recovery after giving birth is faster and better for the children, so really don't feed yourself so much in order to have a big fat boy, which will increase the risk of hypertension during pregnancy. If you get high blood pressure during pregnancy, it may threaten your life, and you will have two lives if you are not careful. Stretch marks are because the children in our stomachs grow too fast, so the meat in our stomachs can't keep up with the speed of the children, so our skin is torn and a series of purple scars are formed. This is our stretch mark, which can be prevented. When you are pregnant, you can apply something like olive oil to your stomach to keep it moist. Too dry can also lead to too many stretch marks. If you have already given birth, you can do some aerobic training to make your stomach shrink back to its original shape first, and then you can apply something, such as some scar-removing drugs and creams, which can make people you know lighter. If you are really fat during pregnancy, resulting in many people, you may have to go to the hospital for surgical resection. For example, if we use lasers to lighten their colors, they look as if we can't see them. If we want to get rid of them completely, it depends on our physique.
