The symptoms of jaundice include the manifestations of jaundice itself, and the manifestations of jaundice related complications. For jaundice itself, the most obvious symptom is yellowing of the skin, which can depend on the extent of the yellowing of the skin. If the yellowing is only in the eyes or face, which is common in the first two weeks of life, however, if the whole body is yellow, especially to the palms of the hands and feet (including the palms of the hands and feet), it means that the child has very serious jaundice. Time is also a concern. For a full-term newborn baby, jaundice can be present within 2 weeks, but the yellow color will fade on its own in about 2 weeks. If the yellowing of the skin worsens or does not subside in time, it is also necessary to seek medical attention. Other symptoms about jaundice include for example lethargy, depression, convulsions, screaming, poor appetite, etc. It may be related to liver disease in some children, and some may be related to severe jaundice causing kernicterus. For baby jaundice, parents should promptly distinguish whether it is pathological or physiological and follow up with strict tests as prescribed by the doctor to avoid delaying the diagnosis and treatment of the primary cause of jaundice or neurological complications due to severe jaundice in early neonates. To summarize, the severity of jaundice within one week of age must be taken very seriously, and jaundice that does not subside for a long time also needs to be monitored.
