What is physiological jaundice? Difference between physiological jaundice and pathological jaundice

Most of them appear on the third day of life, with the earliest on the second day and the fifth day as late. In mild cases, jaundice is pale yellow, confined to the neck, or affected to the trunk, and the sclera may also be yellow, which subsides after 2 3 days, and returns to normal on the 5th and 6th days**. More than 2 weeks is called prolonged jaundice, and other causes such as breast milk jaundice should be considered.

Physiological jaundice can heal on its own, and feeding more sugar water can speed up the resolution of jaundice, and it is not necessary. In severe cases, phototherapy should be given and further investigation should be performed to rule out pathological jaundice.

Not serious! Physiological jaundice, which means that it is the kind that babies will get, as long as you take good care, you can generally retreat in the confinement! Take the baby to bask in the sun more, give the baby more glucose water, let the baby defecate more, so that the jaundice will be good quickly!

Physiology is very easy to get good, and you don't need to ** it.

1. Physiological jaundice: full-term infants (newborns with a gestational age of 37 weeks but less than 42 weeks) appear jaundice 2 to 3 days after birth; Preterm infants (newborns with a gestational age of less than 37 weeks) develop jaundice 3 to 5 days after birth.

Pathologic jaundice: appears within 24 hours of birth.

2. Physiological jaundice: full-term infants reach a peak in 4 to 5 days, and subside in 5 or 7 days, no later than 2 weeks in the cave; Preterm infants reach a peak in 5 7 days and resolve in 7 9 days, which can be delayed up to 3 to 4 weeks.

Pathologic jaundice: jaundice lasts for a long time: >2 weeks in term infants and >4 weeks in preterm infants.

3. Physiological jaundice - the degree of jaundice is mild, jaundice is mainly distributed in the face and trunk, and there is often no obvious jaundice in the forearms, calves, palms and feet.

Pathological jaundice - ** is golden yellow, even the former jujube orange yellow, or jaundice all over the body, palms and soles of the feet also have obvious yellow staining.

4 Physiological jaundice: jaundice progresses slowly, and bilirubin rises <5mg dl per day.

Pathologic jaundice: deepens a lot in a day, with a rise in bilirubin greater than 5 mg dl per day.

Parents should pay attention to the child's jaundice after the baby is born, because jaundice has the difference between physiological jaundice and pathological jaundice, and physiological jaundice and pathological jaundice can be judged from the time when jaundice appears, the time when jaundice subsides, and the value of bilirubin rises. There is a difference between physiological jaundice and pathological jaundice in the baby, and pathological jaundice may cause some other effects on the child if it is not detected in time, so you should pay attention to the specific situation of jaundice.

Within 2-3 days after birth, the baby will have different physiological jaundice. The baby's skin is light yellow, the scleral patch antenna is pale yellow, and the urine is slightly yellow. The baby's mental essence is not prone to other discomforts, and jaundice is most significant in 4-6 days.

Pathologic jaundice usually occurs within 12 to 24 hours of birth. or recurrence after the jaundice has subsided. Pathologic jaundice has a longer delay than physiologic jaundice.

Jaundice occurs horizontallyPhysiological jaundice generally occurs on the face, head and neck, the skin is light yellow or apricot yellow, the sclera is yellowish, and the urine is yellow, but diapers are not easy to color. Pathological jaundice is generally severe, orange-yellow, the limbs, palms, soles of the feet are very yellow, and diapers will continue to have significant pale yellow.

Generally, pathological jaundice will occur in two or three days after the baby is born, and it will peak in five or six days, and then it will gradually subside, similar to two weeks or so, but it is also very likely that the relative will be slightly later. Physiological jaundice will occur within 24 hours after the baby is born, and the trend is very fast, but the time period for subsidence is generally longer, and it is likely that it will subside to a certain extent in a month, and some will re-emerge after subsidence, and even aggravate. Physiological jaundice baby's skin and sclera are pale yellow, and usually limited to the face and shoulders and other positions, the color of the stool is yellow, and the small solution does not yellow.

In pathological jaundice, the baby's ** color is very dark, and even shows orange-yellow and orange-yellow. There are many locations of jaundice, and even the palms of the hands and soles of the feet are all yellow, and the color of the stool is likely to show the color of clay, and the tone of Xiaojie will also be yellow, and the diapers are not easy to wash.

The main characteristic of children with physiological jaundice is that the general condition is relatively good, jaundice gradually occurs two to three days after the birth of full-term, reaches its peak in four to five days, and gradually subsides after six to seven days, and is not easy to exceed two weeks at the latest. Jaundice in premature infants occurs gradually over 4 to 5 days after eruption, peaks in 5 to 7 days, and gradually subsides in 7 to 9 days, up to 3 to 4 weeks. The daily serum protein teflavin elevation is less than 85 micromoles per liter.

Pathologic jaundice is characterized by jaundice that occurs within 24 hours of birth, with serum bilirubin exceeding 221 microbars per liter in full-term adolescents and 257 in preterm infants or more than 85 per day.

The time of appearance is different, pathological jaundice generally appears 1 2 days after the baby is born, physiological jaundice generally appears after the baby is born 3 4 days later, the time of subsidence is different, the pathological jaundice subsides relatively late, about 2 3 weeks, physiological jaundice generally begins to subside in about a week, the color is different, pathological jaundice, the child's ** color is generally golden yellow or orange, physiological jaundice, the child's ** is generally light yellow.

The symptoms of physiological jaundice and pathological bile are different, the appearance and regression time are different, pathological jaundice will appear within one or two days and develop very quickly and subside very late, physiological jaundice will only appear two days after about two weeks to subside, the color and degree are also different, pathological jaundice is darker in color, physiological jaundice is light yellow in color, the medical history is not the same, and the mental condition is not the same.

The two can be distinguished by causes, conditions, symptoms, specific manifestations, and methods. Pathologic jaundice often appears within 24 hours of birth. Physiological jaundice will not appear until about 2 to 3 days after the birth of the newborn, which is the biggest difference.

Physiological jaundice is caused by the child's hepatobiliary function is not fully developed, pathological jaundice is due to neonatal hepatitis, or biliary obstruction, hemolysis, these diseases are not the same between the two, and pathological jaundice is more serious.

The jaundice value can be measured, the child's symptoms can be observed, and the time of the child's onset can be observed. You can observe the child's **, and you can go to the hospital for professional identification.
