Congenital heart disease is a structural problem that occurs in the baby’s heart at birth, and it often arises after a woman is pregnant or without ever realizing she is pregnant. About nine out of more than 1,000 newborns have congenital heart disease. It is also the most common type of pediatric cardiovascular disease in China, with an incidence of about 6 to 8 percent of births, or 1 in 11 infants encountered. How to help mothers-to-be protect themselves and reduce the risk of congenital heart disease in their newborns. First, talk to your doctor more often. Although it may sound cliché, it is very practical and effective. Mothers-to-be need to go to the hospital regularly to check if they have diabetes, measles or influenza, and to take early action under the guidance of their doctors. Second, women are required to take a variety of vitamins daily, including 400 mg of folic acid and folic acid supplements. Folic acid is effective in preventing congenital heart disease, and it is also known for its role in preventing neural tube abnormalities, and women are encouraged to take proper supplements in the first three months of pregnancy. According to the Cardiac Society, it is also very important to always consult your doctor about the use of medications, which largely prevents the possibility of fetal malformations due to indiscriminate use of drugs. This guideline is especially important for Chinese people who are used to buying their own medication for health care. Finally, stay away from people with influenza and other illnesses that can cause fever. In the first trimester, any illness associated with fever is likely to double the risk of heart disease in the fetus.
