Women during pregnancy require an adequate amount of folic acid (Vitamin B9). Sufficient levels of folic acid are very helpful in eliminating the possible severe birth defects that would involve the brain of the baby and spine, thus protecting both the mother and the unborn baby.
Taking recommended folic acid before conception and in early pregnancies can help in decreasing the chances of severe birth defects of the baby in terms of brain and spinal cord.
Did you follow the diet, which included the following:
What Is Folic Acid (Vitamin B9)?
The synthetic form of folate is known as folic acid which is a water soluble B-vitamin that is naturally present in foods. It is an important part of the DNA synthesis, cell division, red blood cell formation, and development of the nervous system.
Folic acid is particularly crucial during pregnancy to form the neural tube which in the future grows to form the brain and the spinal cord of the baby.
Folic Acid: Why You Need It during pregnancy.
The rapid cell growth and placental development of pregnancy predisposes the body to an excessive demand of folic acid. Adequate intake helps:
- Support placental growth
- Promote growth of fetus brain and spine.
- Reduce the neural tube defects (NTDs).
- Prevent maternal anemia
The neural tube develops within the first 28 days of pregnancy and in most cases, the neural tube develops even before the woman is aware of the pregnancy. This is the reason why the intake of folic acid is very critical before conception.
Daily recommended dose of Folic Acid
Those in charge of health advise:
- 400 mcg/day female pregnancy planners.
- 400–600 mcg daily during pregnancy
- Increased dose only in case of high risk pregnancies.
Never take larger doses without the advice of the health care provider.
Risks of Folic Acid Deficiency During Pregnancy
Maternal Complications:
- Miscarriage: Exposes one to miscarriage and abortions.
- Risk of pre-eclampsia-Lack of adequate folic-acid levels may put the pregnancy at risk of pregnancy complications. Such as pre-eclampsia (a condition where pregnant ladies develop high blood pressure).
- Megaloblastic Anemia: Megaloblastic Anemia Signs and Symptoms.
Fetal Complications:
- Neural Tube Defects (NTDs): A deficiency of folic acid can cause grave health complications in the mother as well Fetal Complications. Reduced levels of folate in a person’s body lead to conditions such as spina bifida and anencephaly. Among the most severe complications related to a deficiency of folic acid, one is neural tube defects (NTDs) which include spina bifida and anencephaly.
- Inadequate folate may result in the fetus having limited growth and lead to having low weight after being born.
- Too little folic acid in your diet may result in having a baby who comes too early (preterm).
- Developmental Delays: A pregnant woman who does not receive adequate folic acid also exposes the child to cognitive and behavioral developmental delays.
Folic Acid Deficiency in Pregnant Women-Causes.
- Poor dietary intake
- Gastrointestinal disease like the celiac disease or inflammatory bowel disease.
- Nutritional needs during pregnancy.
- Prenatal supplement deficiency.
- There are some drugs (e.g., anti-seizure drugs) which affect absorption.
Prevention and Treatment of the Folic Acid Deficiency:
A. Dietary Modifications:
Cereals, whole grains are rich folate foods. Folates contain veggies like spinach, kale, citrus fruits and beans and lentils and even the bread fortified with folic acid. Enriched foods like bread, pasta, cereals and orange juice come in particularly handy like orange juice, pasta etc.
The diet includes Folate Rich Foods as follows:
| Food Source | Approx. Folate (mcg) |
| Spinach (cooked) | 260 |
| Lentils | 180 |
| Fortified cereals | 100–400 |
| Citrus fruits | 40–50 |
| Beans & chickpeas | 140 |
| Eggs | 25 |
Particularly useful are foods that contain folic acid, e.g. bread, pasta, and cereals.
B. Folic Acid Supplementation:
- Within the first 3 months of pregnancy, Health care providers may advise that women should consume 400 mcg/day and that more intense doses are only prescribed in high-risk women under the medical guidance before several weeks of pregnancy.
- Some drugs if used against seizures may hinder the folic acid absorption, if your previous pregnancy was related to the risk of neural tube defects.
C. Regular Prenatal Care:
Determine the level of folic acid, hope that mothers will be given the nutrition they need. Screening of other NTD as well as routine visits. Risk factors will enable health care providers to early testing to identify nutritional deficiencies.
D. Awareness and educating the community through IEC/BCC.
Public health campaigns based on Information, Education and Communication (IEC), Behavior Change Communication (BCC) assists in creating awareness about:
- Importance of folic acid
- Early supplementation
- Prevention of birth defects
- Nutrition education of the mother.
Key Message :
Deficiency of folic acid during pregnancy can be avoided. Proper pre-pregnancy and intra-pregnancy intake may help to substantially minimize maternal and fetal morbidity such as neural tube defects and low birth weight.
Creating awareness, enhancing nutrition, supporting the use of supplements and reinforcing of prenatal care services are important measures to healthier mothers and babies.
