What are the symptoms of folic acid allergy?

Folic acid is a very important supplement for many women who are preparing for pregnancy and women in the early stages of pregnancy. Women use folic acid to ensure that the fetus will not have deformities, but some women will experience allergies after taking folic acid. However, many women do not know what symptoms they will have after being allergic to folic acid. So, what are the symptoms of folic acid allergy?

First, what are the symptoms of folic acid allergy? There are fewer adverse reactions to taking folic acid tablets, and allergic reactions are rare. Long-term use of the medication may cause gastrointestinal symptoms such as anorexia, nausea, and abdominal distension. When taking large amounts of folic acid, the urine may turn yellow. It is particularly important to note that megaloblastic anemia caused by vitamin B12 deficiency cannot be treated with folic acid alone, and patients who are allergic to folic acid tablets are not suitable for taking it.

Second, although folic acid supplementation for pregnant women can help reduce the risk of congenital diseases in the fetus , it does not guarantee that the baby will not have neurological malformations, and long-term excessive intake can also have serious negative effects on the human body. Pregnant women should take folic acid under the guidance of a doctor. If they have given birth to a child with a neural tube defect, they should take it under the advice of a doctor. In fact, folic acid itself has no toxic side effects. The side effects of folic acid mentioned in daily life mainly refer to the problem of overdose. Allergic reactions to folic acid are rare, and even if they occur, they vary from person to person. As a vitamin that can be dissolved in water, it is fine if the amount of folic acid exceeds 20 times the minimum requirement of the human body. The excess folic acid will be excreted from the body in urine.

What are the symptoms of folic acid allergy? People with allergies may be allergic to folic acid. Pregnant women will not experience allergies if they have enough folic acid, because the folic acid in the mother's body will be consumed in the early stages of pregnancy and pregnancy. Timely and large amounts of folic acid supplementation can reduce the chance of fetal malformations and diseases caused by folic acid deficiency. In patients with normal renal function, toxic reactions rarely occur. Allergic reactions may occasionally occur. Some patients who take large amounts of folic acid over a long period of time may experience gastrointestinal symptoms such as anorexia, nausea, and abdominal distension. When taking large amounts of folic acid, yellow urine may appear. Oral folic acid can quickly improve megaloblastic anemia, but it cannot prevent the progression of neurological damage caused by vitamin B12 deficiency. If folic acid is still taken in large doses, the vitamin B12 content in the serum can be further reduced, which will cause the neurological damage to develop in an irreversible direction.
