What are some causes of folic acid deficiency?

The causes of folic acid deficiency include diseases that affect the absorption of folic acid during digestion, excessive alcohol intake, hemolytic anemia and a diet that is low in fruits and vegetables, according to MedlinePlus. Crohn's disease and celiac disease are some of the diseases that hinder folic acid absorption.

Folic acid, or folate, deficiency is a condition in which a person has an insufficient amount of folic acid in the body, notes MedlinePlus. People with folic acid deficiency may experience symptoms such as fatigue, tongue inflammation and mouth ulcers. The condition may also cause complications such as low red blood cell count, low white blood cell count and low platelet count.
