During pregnancy and while breast-feedingthe body requires more folate or folic acid . A developing fetus needs folic acid to grow, especially the development of the brain and spinal cord.

It is recommended that if you are trying to get pregnant or if you are pregnant, you need to ensure that you are getting enough folate in your diet each and every day. Taking prenatal vitamins could help ensure you do not fall short of key nutrients, including folate.

Drinking Alcohol

Alcohol decreases absorption of folate by your body, so drinking alcohol to excess may lead to folate deficiency.

Certain medications

Medications including methotrexate, phenytoin, sulfasalazine and trimethoprim may lead to folate deficiency due to its impact on intestinal folate absorption, utilization and conversion into an active form of folate.

Certain health conditions

Certain health conditions may cause folate deficiency such as:
Most nutrients are absorbed by your small intestine, so certain intestinal diseases (colitis, Crohn’s disease, or coeliac disease) or surgery, could mean your intestines are unable to properly absorb folate from your food and this can result in a folate deficiency.

Surgeries such as gastrectomy, may lead to poor folate absorption. This is a more uncommon way that one may experience folate deficiency but it is still a possible cause of folate deficiency.

If you have or are currently experiencing any of the above conditions, you should consider taking a folate test, especially if you are experiencing the symptoms of folate deficiency.
