Can rule out biliary atresia

Newborn babies will have jaundice three or four days after birth. Most babies have physiological jaundice, and only a few have pathological jaundice. Physiological jaundice will gradually subside, but if the bilirubin level is too high, it will have a certain impact on the baby's health. The doctor will prescribe some jaundice-reducing drugs for treatment.

1. Many newborns may have biliary atresia after birth. It usually takes at least one month to rule out this type of condition. Usually many newborns will have jaundice after birth, but it will gradually disappear over time.

2. When a newborn is just born, there may be some abdominal swelling, ascites, etc. However, biliary atresia is a completely different disease. It will become more and more serious over time. Neonatal jaundice will not improve, and many organs in the body may deteriorate.

3. Therefore, to confirm this disease, the child needs to be hospitalized for observation for at least one month. During this month, the child's growth changes should be closely monitored. If it is confirmed to be biliary atresia, surgery is required, otherwise the child has no hope of survival. This type of disease can usually be fully diagnosed after more than three months.

1. In the early days, it was believed that this disease was a congenital bile duct abnormality, which was related to the stagnation or disorder of the bile duct system development during the 4th to 10th week of embryonic period. However, no biliary atresia has been found in the dissection of the biliary system of a large number of aborted or premature infants. On the contrary, recent studies have provided more evidence to support that this disease is acquired.

2. Generally speaking, it is possible to know whether the baby has biliary atresia when the baby is 3 to 5 months old.

Causes of Biliary Atresia

1. Viral infection theory: The research hotspots of the pathogen are mainly concentrated on cytomegalovirus (CMV), rotavirus (RRV), reovirus type III and human papillomavirus (HPV).

2. Immune damage theory: Children with this disease may have some genetic defects, which activate the innate immune system and make this system work together with the acquired immune system to cause the occurrence and progression of the disease.

4. Genetic etiology theory: It is generally believed that BA is not a hereditary disease, but studies have found that it has a certain familial inheritance.

5. Hypoplasia theory: Abnormal changes in the biliary system in embryonic biliary atresia can be detected before birth.

In fact, biliary atresia cannot be detected before birth and cannot be prevented. The cause of biliary atresia is still unknown. Experts believe that it is related to congenital developmental abnormalities and infectious factors. There is currently no evidence that biliary atresia is a genetic disease. How many months does it take to rule out biliary atresia? I have shared this with you above. When biliary atresia occurs, you must take your baby to a regular hospital for treatment.
