Many expectant mothers know that she needs to supplement folic acid, but what exactly is folic acid?Why do everyone say to add?How to replenish folic acid scientifically and reasonably?In this regard, the chief physician of the obstetrics of the obstetrics and gynecology hospital of Hangzhou Municipal Obstetrics and Gynecology Hospital answered.
What exactly is folic acid?
Folic acid was the earliest growth factors found from spinach. It is named after the rich content of green leaves. In fact, it is a water -soluble B vitamin.
Why add folic acid?
Folic acid deficiency may have these terrible consequences:
1. Causes various pregnancy diseases, the most serious is to cause fetal nerve tube malformations, including brain -free, brain swelling, and spine bales.
Children without brain and brain swelling generally die for a period of time after birth. Although children with spine cracks can survive, they bring heavy mental stress and economic burdens to society and families.
2. It will cause diseases such as limited growth of fetal growth, hypertension during pregnancy, and giant red blood cell anemia.
Due to the changes in the physiology of the maternal body during pregnancy, the demand for fetal growth and development of fetal growth and development has increased significantly.The human body itself cannot synthesize folic acid, and can only be supplemented by food and folic acid nutrients.
However, the stability of folic acid is very poor. The loss rate in the process of food storage, processing and cooking is extremely high. It is difficult to rely on food to supplement sufficient amount of folic acid.At this time, we need to consume extra folic acid nutrition agents.
How to add folic acid?
Women without high -risk factors are recommended to supplement 0.4 mg/day or 0.8mg/day from possible to at least 3 months before pregnancy or before pregnancy, until 3 months of pregnancy.
Some special groups, such as babies who have been pregnant with neurotranscene, or they are taking certain antiepileptic drugs, etc., you need to supplement more high -dose folic acid or extend the time to supplement folic acid.
In short, in the early stages of pregnancy and pregnancy, special groups are recommended to consult doctors in advance for personalized supplements.
In addition, men also need to supplement folic acid.Many men think that pregnancy is mainly a wife’s affairs. All he has to do is stay away from tobacco and alcohol and coax his wife to be happy, but it is not.
Folic acid is an important substance to improve sperm quality.If the content of folic acid in men’s body is low, the number of sperm and ability to move will be reduced, which will reduce the chance of women’s conception.
Therefore, it is recommended that "preparing for pregnancy" should also start taking folic acid 3 months in advance, take 0.4 mg daily, and be discontinued after the wife is pregnant with the baby.
Why start at least 3 months in advance to supplement folic acid?
Related research at home and abroad found that taking 0.4mg folic acid daily, although the average folic acid concentration in the body has increased a lot after 4 weeks, it has not yet reached the standard; it can reach the level of effective prevention of neural tube defects when it is taken until 3 months.Therefore, it is recommended to start supplementing folic acid at least 3 months before pregnancy.
What are the precautions for taking folic acid?
1. Folic acid is recommended to take it on an empty stomach in the early morning. It can be eaten half an hour before breakfast to one hour. The absorption effect is the best.
2. Folic acid should not be taken at the same time as vitamin C to avoid affecting folic acid absorption.In addition, alcohol, tea, spicy stimulus and greasy foods will also interfere with the absorption of folic acid. Preparing for pregnancy and pregnancy should be avoided as much as possible.
3. If other drugs must be taken, it is recommended to be more than half an hour interval.
It should be noted that although ingesting folic acid is important, it cannot be taken in too much. Long -term large doses (> 1mg/day) supplement folic acid may generate health risks, such as affecting the absorption of zinc, reducing immunity, even increasing the colorectal intestineRisk of cancer disease, etc.
If yellow urine, or gastrointestinal symptoms such as anorexia, nausea, and abdominal distension, you should be alert to whether it is caused by excessive amount of folic acid, and you should go to the hospital for examination in time.
