Signs of folate deficiency anemia most of the time are subtle. [4] Anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate deficiency in adults. [1] Folate deficiency anemia may result in feeling tired, weakness, changes to the color of the skin or hair, open sores on the mouth, shortness of breath, palpitations, lightheadedness, cold hands and feet, headaches, easy bleeding ...
Methylenetetrahydrofolate reductase deficiency is the most common genetic cause of elevated serum levels of homocysteine (hyperhomocysteinemia). It is caused by genetic defects in MTHFR, which is an important enzyme in the methyl cycle. [1] Common variants of MTHFR deficiency are asymptomatic and have only minor effects on disease risk. [2]
Folate in the form of folic acid is used to treat anemia caused by folate deficiency. [3] Folic acid is also used as a supplement by women during pregnancy to reduce the risk of neural tube defects (NTDs) in the baby. [3] [10] NTDs include anencephaly and spina bifida, among other defects.
3. Folic Acid. Folic acid is a synthetic form of folate, a B vitamin found naturally in many foods. If you eat lots of dark leafy greens (like broccoli, spinach and asparagus), beans, nuts, seeds ...
Causes: Vitamin B12 deficiency, Folic acid deficiency, Malabsorption, Alcoholism: Risk factors: Bone marrow failure, hematologic malignancy: Diagnostic method: Symptoms, Complete blood count, Peripheral blood smear, Vitamin B12 level, Red cell folate level
Macrocytic anemias have several causes but with the implementation of folic acid fortification in North America, folate deficiency has become a rare cause of megaloblastic macrocytic anemia in that part of the world. [1] In this region, Vitamin B 12 deficiency is a far more common cause of megaloblastic macrocytic anemia. [1]
As a consequence of the biochemical reactions in which homocysteine is involved, deficiencies of vitamin B 6, folic acid (vitamin B 9), and vitamin B 12 can lead to high homocysteine levels. [2] Other possible causes of hyperhomocysteinemia include genetics, excessive methionine intake, and other diseases. [3]
One important note: Excess biotin can also "cause incorrect results in certain laboratory tests that look at thyroid levels and blood markers that can help diagnose heart attacks," says Dr. Castillo.
