Having too little folate (vitamin B9) in your blood causes folic acid deficiency anemia. Folate is necessary for your body to make new red blood cells. Your body needs red blood cells to carry oxygen to your organs. Not having enough red blood cells causes a condition called anemia, which can make you feel weak and tired.

Your baby may be at higher risk of developing serious birth defects like spina bifida if you have folic acid deficiency anemia during pregnancy. Spina bifida causes the baby’s spinal column to be malformed. Symptoms may include:

Pale skin
Decreased appetite
Being grouchy (irritable)
Lack of energy or tiring easily
Diarrhea
Smooth and tender tongue

The symptoms of folate-deficiency anemia may look like other blood conditions or health problems. Always see your healthcare provider for a diagnosis.
