If you want to protect the health of adults and children after pregnancy, scientific preparation for pregnancy is essential. When it comes to life when preparing for pregnancy, people are most concerned about eating, and they are a little too concerned, not only eating a lot, for fear of not having enough nutrition, but also eating carefully, not eating this and not touching that. In fact, the diet during pregnancy preparation is not special, as long as the calories are reasonable and the nutrition is balanced, there is no need to deliberately avoid eating. 2. Add some exercise. When preparing for pregnancy, you should do moderate exercise. In fact, the entire pregnancy period should be moderate exercise, not to mention the preparation for pregnancy. Many people usually do not have the habit of exercising, and when they hear that pregnant women should exercise after pregnancy, they suddenly increase the amount of exercise, but will have adverse reactions. During the preparation period, let your body gradually adapt to the state of moderate exercise, to pregnancy and postpartum to lay a good foundation. 3, obesity is a big taboo obesity not only affects the appearance, but also affects the whole process of pregnancy and childbirth.

Pregnant women over 35 years old are considered to be of advanced age. Many women do not get pregnant and have children when they are young for various reasons, so they have to take the risk of getting pregnant at an advanced age. This risk must be understood in advance. Generally speaking, no matter how meticulous and comprehensive the work of pregnancy preparation is for people over 35 years old, it is impossible to achieve the most ideal state, and the possibility of infertility, miscarriage, fetal malformation and complications during pregnancy and childbirth are significantly higher.
