When a child shows signs of discomfort such as poor appetite, yellow face, yellow urine, vomiting, etc., many parents may associate their child with hepatitis. In fact, there are many liver diseases in childhood that do not have any special manifestations at the beginning of the disease, and the child’s appearance is not significantly different from that of a normal child, but liver function is found to be abnormal during physical examinations or routine checkups for other diseases, and even cirrhosis has already occurred in some children at the time of consultation. Therefore, occult liver disease in children should attract the attention of parents and society. The following are several common occult liver diseases in children: 1, viral hepatitis B China is a large country with hepatitis B. Vertical transmission from mother to child or long-term close contact with people infected with hepatitis B virus is an important way for children to be infected with hepatitis B virus. I found in the work of many children with hepatitis B clinically there are no obvious symptoms, no facial yellowing, eating and playing as usual, only to be found to have hepatitis B at the time of medical examination before entering nursery or school, a small number of children found to have hepatitis B when the liver has sclerosis. Reminder – if the mother is infected with hepatitis B virus or in close contact with a person infected with hepatitis B virus for a long time, in addition to the required vaccination against hepatitis B, it is best to have regular checkups under the guidance of a doctor in order to better prevent and treat hepatitis B and reduce the illnesses and pains caused by hepatitis B in children. 2, fatty liver With the improvement of living standards, the number of obese children in the global rapid increase, fatty liver disease has become its most important a chronic liver disease. China’s Ministry of Education, Ministry of Health and other five ministries and commissions jointly organized the national student obesity survey shows that the obesity rate of students aged 7-12 years old in the city reached 12%, while another 100 obese children aged 10-14 years old inspection statistics show that the fatty liver detection rate of 18%, therefore, it is estimated that the prevalence of fatty liver in children in China is 2% Therefore, the prevalence of fatty liver in children is estimated to be 2%-4%. Since most children with fatty liver are asymptomatic, parents are easily negligent and do not receive timely and effective treatment, and some children eventually develop cirrhosis of the liver. Reminder – fatty liver in children should attract the attention of parents, obese children should be under the guidance of doctors for liver function or liver B-type ultrasound examination. 3, hepatomegaly The disease is a congenital abnormal copper metabolism disease, the parents can carry the gene that causes the disease without the disease. Early detection and early treatment of the disease has a good prognosis and life is generally unaffected. I have found that many children with the disease have no obvious clinical symptoms in the early stage, and when diagnosed, they already have cirrhosis, decompensation, and neurological involvement, and the treatment is poor, and the time for treatment is missed. Reminder – parents find that the child’s liver function is not normal when the cause is not clear, it is best to go to a specialist hospital for further consultation and treatment. 4, glycogen accumulation disease This disease is a congenital disorder of glucose metabolism, some children can have growth retardation, hepatomegaly resulting in abdominal enlargement and other manifestations, serious children also appear convulsions; but there are many children clinically manifested only as “smaller, bigger stomach”, intelligence and movement compared to normal children no significant differences, not The child’s diagnosis and treatment are delayed due to the lack of attention from parents. Reminder – parents who find that their children have growth retardation, abdominal bulge, even if there are no other abnormalities, it is best to go to the hospital to find out whether the child has hepatomegaly, and if the hepatomegaly need to further exclude the possibility of the disease.
