Folic Acid Deficiency occurs when the body does not get enough folate, a type of B vitamin essential for producing red blood cells and DNA. This deficiency can lead to symptoms such as fatigue, weakness, and irritability. It is particularly important for pregnant women, as low levels can increase the risk of birth defects in the developing fetus. Common causes of folic acid deficiency include poor diet, certain medical conditions, and the use of specific medications that interfere with folate absorption. Foods rich in folate include leafy greens, legumes, and fortified cereals, making it important to maintain a balanced diet to prevent this deficiency.
