The possibility of pregnancy in hepatitis patients is a very important issue, and a poor solution may cause lifelong regrets. When pregnancy occurs, the burden on the liver must be significantly increased, so attention should be paid to contraception when the liver function is abnormal. After the symptoms disappear after rest and treatment, the liver function returns to normal and remains stable for a certain period of time (at least six months), and then pregnancy is carried out when the mother is physically and mentally healthy, and a healthy and lively little baby will definitely be born. Pregnancy during acute hepatitis can increase the incidence of fetal malformations, and can also aggravate the pregnancy reaction with increased nausea and vomiting, which seriously affects eating. Sometimes the gastrointestinal symptoms of hepatitis are often mistaken for pregnancy reactions and delay the disease. The incidence of preterm delivery and perinatal mortality increases significantly when hepatitis is present in late pregnancy. Because the virus can infect the fetus via the placenta, miscarriage, premature birth, stillbirth and neonatal death are likely to occur. There is also an increased chance of gestational hypertension syndrome. Hypertension, proteinuria, edema, convulsions and cerebrovascular accidents may occur in severe cases. The liver is the site of synthesis of coagulation factors, and due to impaired synthesis of coagulation factors caused by viral hepatitis, postpartum hemorrhage is likely to occur during delivery, with an incidence of more than 10%. Therefore, it is important for women during pregnancy to take preventive care and try to avoid infection with all types of hepatitis to ensure the safety of mother and child. During pregnancy, the nutrient requirements of pregnant women increase to supply the growth and development of the fetus. The obvious increase in metabolism reduces the glycogen reserves in the liver, and the metabolism and detoxification of the fetus depends mainly on the mother’s liver, which increases the burden on the liver of pregnant women. Especially in late pregnancy, if combined with gestational hypertension syndrome, ischemic damage to the liver can occur due to systemic small artery spasm, which can easily develop into heavy hepatitis. The physical exertion, bleeding and injury during delivery can aggravate liver damage and can promote necrosis of existing liver tissue. Therefore, the proportion of patients with hepatitis who develop acute or subacute hepatic necrosis during late pregnancy increases. After delivery, liver function is not easily recovered. In conclusion, pregnancy in patients with hepatitis is undoubtedly a serious test for the liver of the mother, who has a poor reserve capacity of her own.
