What Happens If Folic Acid Is Low During Pregnancy?

Written by - Editorial Team
Medically Reviewed by - Dr Malathi J

Pregnancy is a phase where even small nutritional gaps can have a big impact on both mother and baby. One of the most essential nutrients during this time is folic acid. It plays a critical role in early fetal development and supports a healthy pregnancy. When folic acid levels are low during pregnancy, it can lead to serious complications that are often preventable with timely care and awareness.

What Is Folic Acid?

Folic acid is the synthetic form of vitamin B9. It helps the body make new cells, produce DNA, and form red blood cells. During pregnancy, this vitamin becomes even more important because the baby’s brain, spine, and nervous system develop rapidly in the early weeks.

Folic acid during pregnancy supports proper cell division and growth. Many women may not realize they are pregnant during the first few weeks, which is why maintaining adequate folic acid levels before and during pregnancy is strongly advised.

Why Is Folic Acid Important in Pregnancy?

Folic acid in pregnancy is essential for preventing birth defects and supporting maternal health. Adequate intake helps ensure proper development of the neural tube, which later forms the baby’s brain and spinal cord.

Key folic acid benefits during pregnancy include
• Supporting early fetal brain and spine development
• Reducing the risk of neural tube defects
• Helping prevent anemia in the mother
• Supporting healthy placental growth
• Promoting a healthy pregnancy outcome

When folic acid levels are insufficient, these protective benefits are reduced.

What Happens If Folic Acid Is Low During Pregnancy?

Low folic acid levels during pregnancy can affect both the mother and the baby. The impact is most severe in the first trimester, when the baby’s organs are forming.

Second Opinion

Effects on the Baby

Folic acid deficiency increases the risk of neural tube defects. These are serious conditions that affect the brain and spinal cord.

Common risks include
• Spina bifida, where the spine does not develop properly
• Anencephaly, a severe condition affecting brain development
• Low birth weight
• Poor growth inside the womb
• Increased risk of premature birth

Vitamin B9 deficiency can also affect long term neurological development and overall health of the baby.

Effects on the Mother

Low folic acid during pregnancy can also affect maternal health.

Possible effects include
Anemia causing weakness and fatigue
• Increased risk of pregnancy complications
• Higher chances of placental problems
• Reduced immunity leading to frequent infections

Folic acid deficiency can make pregnancy physically more exhausting and increase health risks if left unaddressed.

What Causes Folic Acid Deficiency?

Several factors can contribute to low folic acid levels during pregnancy.

Need an Appointment?

Common causes include
• Poor dietary intake of folic acid rich foods
• Unplanned pregnancy without preconception supplementation
• Digestive disorders affecting nutrient absorption
• Certain medications that interfere with vitamin B9
• Increased nutritional demand during pregnancy

Women with previous pregnancy complications or nutritional deficiencies may be at higher risk and require closer monitoring.

Signs and Symptoms of Low Folic Acid

Folic acid deficiency may not always show clear symptoms, especially in the early stages. However, some warning signs can appear.

Possible symptoms include
• Constant tiredness or weakness
Pale skin
• Shortness of breath
• Difficulty concentrating
• Mouth sores or tongue swelling

If these symptoms appear during pregnancy, it is important to consult a doctor for evaluation and blood tests.

How Much Folic Acid Is Needed During Pregnancy?

Doctors usually recommend folic acid supplements along with a balanced diet. The requirement may vary depending on individual health needs, previous pregnancy history, and risk factors.

Folic acid during pregnancy is most critical before conception and in the first trimester. However, continued intake throughout pregnancy supports ongoing growth and maternal health.

Always follow medical advice rather than self adjusting supplements.

Best Food Sources of Folic Acid

Along with supplements, natural food sources play an important role in maintaining adequate levels.

Folic acid rich foods include
• Green leafy vegetables like spinach and broccoli
• Lentils and beans
• Citrus fruits
• Fortified cereals and grains
• Nuts and seeds

Including these foods regularly helps support a healthy pregnancy and reduces the risk of vitamin B9 deficiency.

How Is Folic Acid Deficiency Diagnosed?

Doctors diagnose folic acid deficiency through blood tests. During antenatal checkups, nutritional screening helps identify deficiencies early.

Early diagnosis allows timely treatment and reduces risks to both mother and baby. Regular prenatal visits are essential to monitor nutritional status and overall pregnancy health.

Can Low Folic Acid Be Prevented?

Yes. Folic acid deficiency is one of the most preventable pregnancy related nutritional issues.

Simple prevention steps include
• Taking prescribed folic acid supplements
• Eating a balanced, nutrient rich diet
• Planning pregnancy with preconception counseling
• Attending regular antenatal checkups
• Managing existing health conditions under medical guidance

Prevention plays a key role in ensuring a healthy pregnancy and safe fetal development.
