If pregnant women lack vitamin A, it may indeed lead to the baby's deformity, so everyone must pay attention to the intake of vitamin A during pregnancy before pregnancy, so as not to cause problems for the baby. But in the early stages of pregnancy, don't take too much. During lactation, women can add an extra 2,500 international units in the first six months, and we can add 2,000 international units in the last six months. Adults only need to eat 65,438+0/2 carrots or a bamboo shoot every day to meet their needs. If they lack vitamin A, they are likely to be deformed.

Many foods are rich in vitamin A, such as animal liver and egg yolk. People need to eat more pork liver, chicken and lean meat in daily life, because the level of progesterone is relatively low in the early pregnancy, coupled with pregnancy reaction and vomiting, so many people have a bad appetite and eat too little food, which will lead to the decline of serum vitamin A level. Early pregnancy is also the lowest stage of vitamin A during pregnancy, and vitamin A has a great influence on the heart development of embryos. If it is seriously deficient, the risk of fetal heart malformation will also increase.

If you supplement vitamin A, you should also be careful not to overdo it, because it may also lead to fetal malformation. For example, taking too much may lead to eye defects, cleft palate, spina bifida, limb defects and other deformities.

If pregnant women take too many vitamins, or lack vitamins, it may lead to fetal malformation. Therefore, everyone should do a good job in relevant examinations before pregnancy, and take some vitamin A with the help of a doctor. But don't take too much vitamin A, it may be deformed, and the health of pregnant women will be affected to some extent.
